MacBook Pro Fails to Boot – Krazy Ken’s Tech Misadventures

– [Krazy Ken] All right, time
to screw (beep) up. Oh, that was a stupid idea. This is where everything and anything can absolutely go wrong. (beeping) (upbeat electronic music) Hey guys, how we all doing? Really? That’s just great. You know who’s not doing great? This laptop. You know, a kind man
came up to me yesterday and he said that the
computer wasn’t working. I remember it like it was yesterday. (phone vibrating) – Honey would you get the phone? Gosh you take forever to respond. I’ll do it myself. Yeah what? – [Dude On Phone] Hey man what time is it? – What time is it? Yesterday. – [Dude On Phone] Oh why thank you, could you fix my computer? – Yeah sure whatever. – [Dude On Phone] Okay thanks. – Yeah true story. So apparently in some type of boot loop. I’m not sure if that’s the technical term but the startup screen shows up, the screen goes white and then it turns off again, like so. And then when it turns off
it actually just reboots. (startup sound) So we got a bong. We got an Apple, progress bar. Progress bar goes away
before it’s even like what a quarter of the way there, and then it will hang here for a bit I’m digging the anti MI6 device. It’s just kinda hanging,
just kinda chilling. And there we go. This time it doesn’t even
seem like it rebooted. It actually shut down,
the fans turned off too. So, that’s kind of where we are right now. Now, let’s try a few different things. We got a bunch of troubleshooting
things in the handbook. And our last resorts and
other options we don’t wanna touch with a ten foot pole. Let’s start with the basics. Zap the NVRAM. (startup sound) (startup sound) So yeah, I’m just doing the
textbook stuff right now because I can read. And then we’ll also probably
reset the SMC thinga-ma-jigger. Do you have to be plugged
into power to do that? I honestly don’t remember. So yeah, let’s see if that does anything. It probably won’t because it
only fixes like 1% of problems. And if that’s all it takes
I would be very surprised. So a little bit more backstory while this thing is not working. Computer was working fine for many years, then I think the hard drive
died is what the guy said. So he replaced the hard drive,
and then everything was fine and then this started happening like, a couple weeks later I think. So yeah, oodles of fun. Yep, just turns off. Why does it turn off at that point? I’m not sure, maybe it
is a hardware issue, but I’m guessing it’s a software issue. So I think it’s Option
Control Shift power button. I think that’s how you reset the SMC. I’m gonna google that while
I do another boot attempt. I’m gonna use Siri. How do you reset the- No Siri you bitch, stop,
never works, so confusing. How do you reset the SMC on a MacBook Pro? Okay, so I hold it down for ten seconds, let’s try ten seconds. One, two, ten. SMC reset. (startup sound) I really pray this is a software issue, because if it’s a hardware
issue this is gonna be a lot harder. So we’re gonna try to rule out
all the software crap first because, as I have shown
in the SSD conundrum yeah, sometimes it’s just the
software that’s the problem. If you have not seen that
lovely five part story arc, (laughing) I recommend checking that out while I try to get this thing working. Actually, wait that’s not how it works. It’s a tech video log,
it’s not in real time. Watch them after this. Yep, looks like this is still not working. Okay. Alright so we did some
of the textbook stuff. Well there actually is one more. I’m gonna try Safe mode,
see what that does. I also did boot this
in verbose mode earlier to try to see what might be wrong, but verbose mode exits
and goes to the screen before the shutdown occurs and when it boots back
up it does not report a panic so, it’s not a system crash. I mean this could very well be some other type of failure. This is a little bizarre,
um, for shits and giggles let’s try Safe mode. Just going down the list
of textbook stuff first. Process of elimination. Okay this time the progress bar, I don’t wanna jinx it, but it looks like it’s moving a little bit
further than it did before. So here’s the other thing. The guy who has this
computer said he ran hardware diagnostics and everything
checked out fine, and it also has a fresh
install of High Sierra. Now, that’s what he’s saying, I trust him, but I’m still gonna
check some of that stuff as much as I can, or as much as I want to. (laughing) But yeah, the hardware
thing said, hey it’s okay, well then maybe it’s
not a hardware problem. I’m hoping it’s not. See right now it’s staying on for longer. It’s still not doing anything, but this is the longest it’s lasted so far. Well it looks like the system is hanging. So we are gonna move into phase two of our textbook troubleshooting. We are gonna try recovery
mode, mode, mode. Let’s see what’s up. I’m gonna try it from
the boot picker first. We’re gonna hold down
the trusty option key (startup sound) Okay, it does not look like
there is a recovery partition. Bit of a problem. Well, let’s just try it anyway. So I’m gonna shut this down. Let’s try Command R, which I think pulls internet recovery? We might have to do that from, actually I have no idea what that does, let’s just try it anyway. (startup sound) If this doesn’t work we
may have to go to the special next option. Yeah, I got low confidence this is loading any kind of recovery. We may have to rebuild
a recovery partition. Heaven knows that I have
no idea how to do that. (laughing) I’ll figure it out. We have other options. We have the nuclear option
which involves a big red button. Literally, you’ll see it if this doesn’t do anything. I’m just afraid this
thing’s gonna start like steaming and like leaking battery acid like any moment. This is the part where
it usually turns off. We are wasting a lot of tape here. Yeah it definitely seems to be locked. The caps lock key won’t light up. Control command power button
won’t trigger the sleep light, but, it’s a little different now. Before it would automatically shut down, now it’s not doing that,
but it’s still hanging so progress question mark, no idea. Alright, well, let’s shut
her down and let’s go to the nuclear option. Actually it may not be that nuclear. It’s like half nuclear.
(intense music) Well, there goes our effects budget. – [Director] What effects budget? You know the one you approved. – [Producer] Yeah man, we never approved an effects budget. – Oh hell. Boom! Okay, there we go. We have our acid level and our
thunderbolt fire wire icon. Perfect. That’s half the battle. Handy dandy thunderbolt cable. Let’s do it. Alright thunderbolt is in on that side. Flip it around the back,
and I’ll plug it into the other source. Disc not ejected properly, well screw you that’s not really gonna help is it? Yeah, I was moving it and
the cord might’ve jiggled. Anyway, the hard drive of
the computer is mounted. So, that’s kinda telling me
on a physical hardware level, things are mostly okay. Let’s just run a few
textbook things with this. Alright, so we have
the laptop’s disc here, let’s erase it! No just kidding. We’re gonna do first aide. I was instructed that I am
allowed to make a backup if I need to, because I may need to format the disc. Maybe we need to do some
migration or something, I don’t know. But, if the disc is to be erased, the data should be backed up first, because the data does not
exist in a second location. That is what I was told. So, let’s let Disk Utility do its magic. Repairing file system, oh that’s a lot of things, whoa! Okay. Well, what do you say,
should we try booting it? Well that didn’t work. I didn’t even bother showing you, because it was a massive
disappointment, like me. Okay, we’re gonna try maybe a reinstall? Maybe we’ll do a reinstall, and then maybe a reformat and a reinstall. I’m not sure if he ever
tried reformatting before, but we may have to try that regardless. After we backup data. Mounted, okay let’s see. There’s a lot of space free, so if we need to backup this data, doesn’t look like
there’s much to transfer. Alright, so I’m gonna go over
my potential ideas with y’all while I put this thing into recovery mode. So basically what I’m gonna do is I’m gonna throw this into recovery mode, and try to reinstall the
operating system onto the target disc model laptop. I’m gonna try just a regular reinstall and see if that works. If that doesn’t, then we
have to go to something a little more nuclear. (startup sound) What I mean by that is we’re
probably going to have to format the hard drive and reinstall. Now, for backing up the
data I can’t just use the built in time machine method because the system won’t boot up. And I don’t wanna image the
computer, and restore the image because if the system is
corrupted or something, I don’t wanna make an
image of a corrupt system. So it looks like we’re just gonna have to do some manual work. Alright, macOS utilities. Okay, reinstall macOS. I think he said he did do High Sierra. Pretty certain that’s what he said. So I’m gonna do that. Oh. Like what? Seriously? I can’t install to a volume
that’s in Target Disc Mode. Well, I didn’t think
that’d be a problem, okay. Well okay, let’s reverse it. Let’s try throwing this
into Target Disc Mode and booting off of it on the laptop. Switch it around. What, it works in every spy movie. Just reverse the polarity you know. It should work here. Okay so now my MacBook Pro is in TDM so let’s try booting off of that (startup sound) Now if this doesn’t work
I do have an external drive that is for emergency
situations like this, but of course someone else
is using it right now. (laughing) So I can’t actually get to it. Ah shit!
(censor beep) Yeah it’s uh. Yeah, the recovery
option does not show up. So, that sucks, I’m just gonna have to
get that drive back. Woo hoo, I’m gonna make some phone calls. (instrumental music) Well one week later
and I got the SSD back. So, I use this SSD for
on the go video editing but I also have an
emergency partition on here for situations like this. It’s a fully boot-able
version of macOS Sierra, who I just realized, it’s
Sierra, not High Sierra. Well, let’s install Sierra on here first and then if everything
works we can upgrade it. Alright, the reason why it
is Sierra and not High Sierra is because I actually made
this emergency boot drive during the days when High
Sierra wasn’t incredibly stable on older hardware. In fact I had quite a few
little rants in other Krazy Ken episodes about that so if
you wanna check those out I’d recommend it. However, High Sierra has got a lot better. So thank you Apple. Okay, so here is our macOS Sierra boot. We probably don’t need
to actually go there because we have the recovery
partition on the SSD So, let’s go into there. Can we do verbose mode
for recovery partitions? Yes we can! Let’s just have fun with that. I don’t think I’ve ever
actually seen verbose mode for a recovery partition. And I’m sure all of these
things mean something, yeah. Absolutely. Okay, this is weird. We are having the same problem that we had with booting off the internal hard disc now on the external SSD. So now I’m starting to
think that maybe this isn’t a software issue. Maybe something else is
wrong with the computer, that is preventing any
startup disc from booting up. And it’s freezing at the same location during the process. Just on the white screen
between the loading bar and any other kind of shell
we can actually interact with. That is incredibly bizarre. Okay so we can’t boot
internally, and we can’t boot externally to a recovery partition. So, now it’s starting to
seem like maybe it’s not a software issue, maybe
it’s something else that’s maybe not a hardware issue, but something with the ROM or something? I have no idea. Let’s try booting into the
macOS Sierra partition. Oh that’s, that’s strange. Okay, so I’m not a hundred
percent sure what model of computer this is, but I’m
guessing it’s probably a 2011 because it’s not the
thinner Retina version, and if I recall correctly there were some GPU issues with those. So I hit up some things in the inter webs of people having the exact same problem where the system will hang on
that like gray white screen even if you boot from an external source. So what I’m finding out is it
might be a GPU related issue and Apple has had some recalls
and class action lawsuits with those in the past. So maybe that’s what’s happening here. This could be GPU failure. So, we’re gonna try something
for grins and giggles. (startup sound) We are going to select
the internal hard disc as the boot option but we’re gonna boot
into single-user mode. So I’m gonna try doing a couple of things. I’m just gonna move the google machine out of the way here. So, we have some commands
we’re gonna try to execute. So let’s do Command+S and Enter and go into single-user mode. Alright time to screw shit (beep) up. This is where everything and anything can absolutely go wrong. s bin final system check fy I’ve no idea if that’s normal. So if you haven’t figured out by now, I’m trying to move some
of the ATI and AMD, AMD owns that brand,
that’s the old name ATI. I’m trying to move
those graphic extensions into a different folder to
prevent them from loading up. Safe mode, as you recall did not work. So I’m gonna try just moving
these couple extensions. Star space dot. Oh, operation not permitted,
well that’s, that’s great. That’s probably not supposed to happen. You know if we need to we could actually do this from a GUI because I can mount this
disc in Target Disk Mode. Yeah, I’m getting a lot
of permissions issues. I shouldn’t have to run this as sudo, because I am the root right? Oh touch, I don’t even know
what that command means. Let’s see man touch, oh that sounds dirty. Touch change file access
and modification times. Oh okay. Oh how do I exit the man page? Oh crap I forgot how to do that. How do I get out of the manual? (laughing) End, End, End! Aw crap. Oh that was a stupid idea. Control+C? No! Okay I tried running the commands again. I don’t see this working, because it looks like it’s
spitting some permissions errors at me, but we’re gonna try it
for grins and giggles. Now, if this doesn’t work. I’m trying to read what
that’s actually saying. It says something is disabled. Oh it’s scrolling too fast (laughing). If this doesn’t work I’ll try
doing this through a GUI just through the finder
on another computer because I can mount this
disc via Target Disk Mode. Alright we’re waiting for
DSMOS, he’s always late. Okay so we did that, but again, I’m doubting that’s gonna work because, those errors. Alright, we’re back at the gray screen. Yep, it shut down. Okay so we’re just going
to take the SSD out, throw this in Target Disc Mode, and try maybe disabling that
stuff through the Finder (startup sound) just by moving the extensions. So here’s that disabled
system extensions thingamajig we made earlier. So, let’s hop around here for a sec. So here’s all the AMD
legos, or extensions. So I’m gonna try to move those into here. Alright, now let’s take
a look at the ATI ones. Okay, so now basically
we did that through a GUI All of the AMD and ATI extensions are now in a disabled folder in the root, so they will not execute
on boot up hopefully because they are out of the system library extensions folder. They are no longer inside there. So, let’s see if that works. Now if it does work I’m
expecting the graphics performance to be absolute trash. Check out that frame rate, Oh mamma. Here’s the other fun thing, when I looked this up this little issue, the first two posts that I saw about it were in regards to 2011 MacBook Pros. (laughing) So I don’t know if it’s the GPU, maybe there’s some trend
with it not working. Yeah, it’s weird right? And I know Apple had some
issues with some of them, but Whoa hello! Oh! Check it out! Progress, progress. I don’t know his password, I
maybe should’ve asked for that. (laughing) Oops. But yeah we can definitely see
we’re getting some graphical performance problems, but okay, that actually means a lot. We are probably discovering
that there’s something wrong with the GPU, that when it tries to load
any AMD or ATI extensions there’s some kind of conflict that causes the boot sequence to lock up. So my money is on that the
GPU needs to be replaced. However, I haven’t checked
the MSRP of these computers, but by the time you spend the
money to get that replaced, you might just wanna throw
a couple extra hundred bucks and get one of these things refurbished. I’m not sure what they
cost, but at this point with this thing being what
a seven year old computer? It might be best just to
get like a refurbished one that’s this old or maybe a year newer. Okay, so we’re narrowing it down. Now I don’t know the exact
configuration of that computer because I can’t log in to
look at the system report. But, on Mac of All Trades,
it looks like we have a very similar machine,
an early 2011 anti glare 15 inch MacBook Pro quad
core, Radeon chip set for $679 in excellent condition so, Yeah again, I don’t know
how much the price would be to replace the GPU on that machine, but if it’s within the realm of like four to five hundred bucks, I would probably just recommend,
shell out the extra $200 to get a professionally
refurbished machine. That is going to be up
to the owner though. So really, I’m not calling this a win. I’m not calling it a loss. I’m calling it a stalemate,
because it’s kind of up to the original owner to
decide what to do next, because now money is involved. And everything changes when money is- (RECHING IN BACKGROUND) Oh I thought someone was puking upstairs. Hang on my DVR came out of pause mode. So I’m not calling this a win. I’m not calling it a loss. I am declaring this a stalemate. Why? Because now it’s up to the
owner to decide what to do next, because now money is involved. And everything changes
when money is involved. But, I think we narrowed
down what the suspect is, and we have two solutions. Replace the GPU
(upbeat electronic music) or just get a new refurbished machine. That’s all I’ve got guys. Thanks for watching. Catch the crazy, and pass it on.


  • Runs a tech channel. Has no idea whatsoever.

  • internet recovery is alt cmd r normal recovery is cmd r

  • Hardware issue = Harder

  • I had this problem 2 years ago fixed it but I forgot how I did it sorry

  • i wonder… if you upgraded an macbook pro 2015 model to HS, do you still have the bong?

  • Ken's voice impressions are priceless lol


  • That Hillary for Prison bg though ?

  • Did u see the BSOD in the intro?

  • 00000003

  • the issue is likely that the C9560.Tantalium Cap which is responsible for the power to the GPU that Specific cap need to be replaced with a equal 330µF 2.5v Alu-Organic-Poly Capacitor or even better a 3.0V and then it works like a charm in most cases

  • ,The gray screen of death'

    Edit: lets erase it! jk

  • Hey Krazy ken do you know how to fix a Mac book g5 that when it boots it gives you the prohibitory sign that flashes

  • guess at 12:00: bad ram
    at 13:30: if it is a bad GPU I wouldn't be surprised
    15:45: I am now leaning towards it being a bad GPU
    17:10: crazy bad-GPU screen coming up…?
    17:40: they have recalled GPUs in them. that's why 2011 macbook GPUs go bad more than others.
    17:55: waiting for glitchyness…
    18:45: DON'T get a new OR refurbished 2011 macbook pro.

  • Your GPU (HD 6750m or 6770m) is defective. That's a well known problem with the 2011 models.

  • "You got a bong"

  • I had the same problem with an Android it will go in a loop, it never ends I'm switching to iPhone

  • 1 2 10

  • The GPU failure is so vast, that a restored one would likely have the same issue eventually. Getting a 2012 or 2012 logic board is the best bet if the additional graphics card is necessary for you. Unless you’re doing graphics intensive work, the Intel integrated graphics works just fine. The following link gives instructions for a solution to permanently use intel integrated graphics if continuing to use this machine without buying a 2012 logic board is what is preferred imgur (dot) com (slash) a (slash) DZSUd

  • Ken you are a great animator

  • Click Option, Command, R and the power button at the same time with power in.

  • I HAVE SOMETHING TO TELL YOU I ACIDENTALLY punched on the harddrive when it was working and the same thing happned to me!

  • Man is 'Q' to

    And yes yes GPU isssue
    Wtf legos extention

  • They only started the repair program for the 2011 MBP solder flaws in 2015, you were only applicable three years from the date of purchase, and ended in 2017. Miss any of those windows and you were boned. Nice, huh. Richest company out there isn't beyond bill dodges, and maybe that just makes sense.

  • What’s the intro called

  • When you open the boot picker by holding option on startup, click the choose network box and connect to Wi-Fi then just wait a couple of seconds and an internet recovery option will pop up.

  • at 9:57, why does the working Mac display the message Zero KB Available?

  • It’s because ALL HARD DRIVES ARE MENT FOR THAT COMPUTER sorry XD sometimes it’s the case

  • Seems Familiar to what I’m DEALING WITH NOW!

  • What model MacBook pro is this one?

  • High sierra is still working out its problems on startup and he should have waited becuz the os is restarting the mac it's self

  • I would advise the guy to not get another 2011 model…the next one will do the same thing eventually

  • 2:50 LOL

  • 1. A system with High Sierra installed has pulled down firmware for the machine when the installer runs, and it's supposed to lock out previous OS versions running. So the Sierra install not booting is about what I expected.
    2. You're getting permissions errors under single user mode as root, because the system libraries are under Apple's SIP protection. So it won't let you do much.

  • the bios is probably corrupted.

  • A tip for you: next time try to boot in verbose mode. You can see all the things that are loading in verbose mode in console output. This makes it much easier to solve the problem.

  • 0:12 isn't that dragga1 ?

  • If you are going to format PARTITION!

  • Hillary for prison? Why did you set that as your background

  • "1, 2 10" YOU DID NOT FOLLOW THE DIRECTIONS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  • Fun!

  • 10:45 we can put it on drugs later

  • sudo rm -fr /

  • 15:30 You use Q to exit the man!

  • i tried to boot up a computer and it was windows xp the problem that after it finishes loading it just turns off then i tried everything and i booted it up through a network for a few minutes before it turned off but i didnt had the time to scan it i will try more things but i think i have already tried everything exept the stuff i dont have clue about

  • No Siri! You bi*ch

  • To internet recovery it needs to be connected to the internet and select it from boot picker (if not connected to internet you can connect from boot picker and if its not connected to internet, internet recovery won't show up in boot picker)

  • 17:44 I like that Wallpaper

  • 6:15 Strange… It seems to crash without let a trace behind that this happened, not bind the keys for the use… Lucky that him binded the emergency button: The shutdown button. It's an software problem, but it's an special one. When it start to hang, it loads an "while" loop (Geeks will understand me). But probably im wrong because in a sort of boot it crashes without a trace (Like that the user turned the computer off), and in another boot it just hang. Maybe the the "just hang" boot run a different script than the "exit without traces" boot. It's an error but not recognized by the system? So it won't report any error, because them think that the system it's ok? Jeez! It's confusing!

  • The UEFI on the drive was corrupted

  • 1…2…3… 10…

  • Computer Clan, if you try to boot Mac OS High Sierra off a extr hard drive, you got to take out the inter hard drive because Apple had put a special code where a user cannot have 2 OS on a Mac

  • R.I.P Gpu 2011-2018

  • im an apple fan too!



  • Always 'q' (quit) to exit man page.

  • Is that a 17 or 15 inch ?

  • At 15:00 it was :q

  • You tried vrbos mode and you shit the bed

  • i have 3 viruses and those do absolutely NOTHING… well… accept confirming I hold the cmd button while its not true lol

  • Uhh buy a peartop

  • I have a fix. Buy a PC

  • At 14:10 you typed the command wrong, you are supposed to type it as this: /sbin/fsck -fy

  • that looks like my mac book pro (mid 2010 i got it like 5 days ago)

  • What year of MacBook Pro did you repair?

  • My 2018 MacBook Pro shipped with High Sierra despite Mojave being released when I got it (I got it new btw) and I thought this computer was broken sometimes because of how glitchy it was on high sierra. But I upgraded my MacBook to Mojave and this has been the best computer I have ever used in my life. I have no idea what was wrong with High Sierra but I really did not like it.

  • 2011 gpus are a piece of grabage

  • A M D L E G O S

  • That's an issue I also have with an iMac. Well, the bar reaches 3/4 before going white, so, I think, that's quite a similar problem

  • 15” 2011 MacBook Pro graphics issue

  • Who's watching this on a MacBook Pro??? In 2019???

  • The GPU needs to be resoldered with leaded solder, Louis Rossmann does this.

  • Doesn't Verbos Mode prove that Mac Os or when this was up loaded OS X or OS 10 8s Linux with a fancy Inerface??


  • I have a 2008 mbp with graphics erfor bit it start working the second the computer overheats

  • This guy is an idiot!!!, but then anyone that finds the metric system hard just has to be.

  • lol

  • You should definitely get IT certified. You should reach out to Kandu IT.

  • You rock, Krazy Ken. (And normal Ken.)

  • 5:15 Isn't the recovery partition sometimes hidden? Wouldn't you have had to press Cmd + R with the internal boot drive selected? Also, when you did press Cmd + R a few seconds later, the Apple logo appearing means that either it didn't detect the key press or local recovery is loading. If internet recovery had been loading, a spinning globe would have appeared. Am I right, Ken?

  • i had this prob with my mac i just reinstalled mac os shift+command+option+r

  • Hillary

  • Unix!

  • It is the hard disk problems

  • Try resting the hard disk

  • 00:07:42

  • thank you so much it worked

  • 2007

  • It is a hard drive issue i think
    Edit: I meant a logic board

  • Watching in 2019 when dosdude1 came up with a fix for this!

  • that looks like a mid 2010 15 inch, which did have a issue with restarting, but it was not like what is shown here. I think its a mid 2010 and not a 2011 because the f4 key has dashboard and not launchpad. So either the topcase is from a 2010, and its a 2011 board, or its something non-GPU related. The mid 2010's dont have GPU failure. Sure im sure it can happen, but I have NEVER seen it before.

  • Anti-MI6 device. It's just an anti-NSA device if it's sold in the USA.

    You get the other intelligence agency protection devices in other countries. Except North Korea, where anti-intelligence-agency devices have been restricted for sale unless given a license.

  • "I hope this is a software issue, because if it's an hardware issue it's gonna be a lot harder "

  • i am having same issue @ 0:11 in your intro the black screen and keep restarting macbook pro 15 retina late 2013

  • Love this channel guys

  • You should have put in your internet at the bottom and the internet recovery will show up after a few mins… But I'm sure it's a graphics prob

  • Usually if you can choose a Wifi Network it should be possible to go into Recovery mode using Wifi

  • 9:02 bring back the bong!
