  • Why is my MacBook Pro **crashing** changing to a blue screen with lines or distorted screen when I open logic or Ableton Live

    Why is my MacBook Pro **crashing** changing to a blue screen with lines or distorted screen when I open logic or Ableton Live. Then I have to restart by long pressing the power button. Can somebody plz help me

    What you describe sounds like a hardware issue. Unfortunately, you'll need to get that checked out by Apple. If you have an Apple Store near you, make an appointment with the Genius Bar and take the machine in for evaluation.

    MacBook Pro 2years old vertical lights come on beeps then I have to restart  anyone help please

    Try resetting your PRAM. If that doesn't work, you may need to get it looked at. It could be a power supply or hard drive issue.

  • My Macbook Pro (15" early 2011) got blue screen every i normally booted it. It only can enter the OS when it's in safe boot. Solution please.

    My Macbook Pro (15" early 2011, Mountain Lion, but after reinstall i change it to snow leo) got blue screen every i normally booted it. It enter the OS only when it's in safe boot.
    I've tried any solution that i got from the internet, such as:
    -Reinstalling the OS X (normal install & clean install)
    -Reset PRAM and SMC
    -Repair Disk Permissions and Repair Disk from Disk Utility (the result is OK. There's no problem)
    -Repair Disk Permissions manually (with Command + S at the beginning of booting)
    -Checking Hardware from Application Installer DVD (result is OK)
    -Checking from Mac Resource Inspector/MRI (result OK)
    -Booting from Recovery Disk is same problem, blue screen
    All of that solution is not working. My Macbook still got light blue screen and sometimes blue screen with lines after apple logo and spinning wheel is shown.
    HDD is in good condition because when it's checked on the other macbook it can be booted. But if you must know, other HDD can't be booted when its plugged to my macbook (blue screen again). If i do safe booting, it works but can't play video and music also photobooth. I got confused with this case.
    Any solution or comment? Thank you very much by the way

    Hi. I'm not trying to rush things, you may have a different problem, but your issue looks quite familiar to me. I recently had a problem with the discrete graphics card (the Radeon GPU) due to overheating, all because a faulty application of the thermal compound in the factory.
    In my case, the problem started slowly and intermittently, a few days after a gaming session (Quake 3) of about three hours (at the moment, I didn't realized that could be linked to the problem).
    This issue is being actively discussed in another threads in this forum, but so far there's enough evidence that it's been causing similar problems for 2011 MBPs owners: screen corruption, black/blue screens, and in some cases, a total inability to boot. Some of the threads I'm talking about:
    https://discussions.apple.com/message/13150366#13150366
    https://discussions.apple.com/message/21110132#21110132
    So far, and since the problem seems to affect only the discrete GPU (that's why you can boot in safe mode) a possible solution is to disable it by removing some extensions which prevent OS X from loading the Radeon drivers. This post describing the process (there are different files involved depending of your GPU version, so make sure you are moving the right ones):
    https://discussions.apple.com/message/22521574#22521574
    In the case your discrete GPU survived and is not permanently damaged, I personally had success by changing the thermal compound myself, which completely fixed the problem (at least for now). I've posted about it here:
    https://discussions.apple.com/message/22630561#22630561
    I hope you can find a solution, believe me I know the feeling when you see your expensive machine turning into a brick and it *****.
    Good luck!

  • I hear my 2010 17" Macbook Pro starting but no picture on screen. HELP!

    I have a 2010 17" macbook pro with no upgrades besides software updates, instillation and small normal things like those. I left it on one night when i fell asleep listening to pandora (internet radio). The next morning i connected the charger to it and tried turning it on. I heard the top left part of the key board (opposite to the cd drive) come to life but couldn't hear the cd drive boot up. Neither the keyboard or screen light up either. I tried changing the RAMs but that was't the case. Any help?

    Is the small "sleep" light at the front blinking or pulsing slowly, or off? 
    It would have gone into sleep mode automatically when the battery falls below a certain point.  Sometimes they need to have a little charge in addition to the power adapter before you can wake them up (by pressing Return, not by pressing the Power switch).  Replacing the RAM in the middle of this state complicates things. 
    You might try a Force Power Off by holding the power down for 10 seconds, wait a bit, then power up again. 

  • HELP! MacBook Pro 17" Won't Boot-Grey Screen-Errors During Verbose Safe Mode Boot

    Booting regularly it hangs on the grey screen, if it does go into desktop, it freezes and won't do anything.
    I did disk check and repair even though it found no errors, and did verify and fix permissions since it showed a LOT of permission errors. Still won't boot into desktop though.
    Ran safe mode verbose and got the following disk0s2 I/O Errors-What does this mean??? Hard drive problem?
    I have reload OS X 3 times in the past few weeks because of freezing issues in Mavericks and stuck with Mountain Lion and it was running fine until I went to boot up this morning after a clean shut down and won't boot up ever since.

  • Why would my MacBook Pro be stuck on a Gray Screen?

    Today when I went to start up my MacBook Pro the screen was completely black (it appeared to be lit but still a  lit black), then I called Apple support and they walked me through a few steps, which just made the screen white. Along with the white screen it displays the Apple logo, then a circle with a line through it (like a do not enter sign), then a gray file with a question mark in it. These 3 images just kind of scroll through on repeat.
    I am not really looking for ways to fix it, I do have an appointment with the Genius Bar, however I was hoping to just understand a little behind why this would be happening... And if you had any ideas on what the cost I'm looking at for the fix. I have a mid 2012 MacBook Pro that has been updated with the latest software. It was working perfectly fine yesterday, and I have never had any problems with it until this right now.
    Please help and thank you so much!

  • MacBook Pro is stuck at start-up screen.

    I've only had my MacBook Pro for a week, and the problem started last night. Whenever I start my computer to OS X, it stops at the screen with the Apple logo and the spinning load icon. I've tried to hold down "C" during startup to activate the Install Disc, but it didn't work.
    The funny thing is that, with Bootcamp, I can hold down the option key and start the MBP up in Windows no problem.
    Can anybody please help me with a solution?

    Run fsck.
    1. Reboot/Startup holding your Command-S key down.
    2. At the command line type the following and hit 'Return.'
    /sbin/fsck -fy
    3. After it has check/repaired your disk, type 'reboot' and hit 'Return' again.

  • My Macbook Pro is stuck on the loading screen

    Hello. My Macbook Pro from late 2012 won't start up normally. It stays stuck on the loading screen with the spinning grey wheel. I reset the PRAM and it did nothing. I did Control-R and trI'd to repair/verify the disk and it said there was nothing wrong. Can anyone help?

    Hi daviscouch,

  • Macbook pro is stuck on my home screen and will not respond to commands

    Hi,
    I just upgraded to Lion this week and came home and opened my Macbook pro. It immediately came on, but took a minute or so for the cursor for the mouse to appear. At the top of the screen "Finder" is highlighted. Problem is, no matter what program I click on, the computer will not acknowledge anything. Help!

    First try a Reset  ( No Data will be Lost )
    Press and hold the Sleep/Wake button and the Home button at the same time for at least Ten seconds... (But can take Longer)... until the Apple logo appears. Release the Buttons
    If no joy... Try a Restore...
    1: Connect the device to Your computer and open iTunes.
    2: If the device appears in iTunes, select and click Restore on the Summary pane.

  • Mid 2010 MacBook Pro won't boot past blue screen

    I've been having problems booting up my MacBook. I can't get past the blue screen. It went from booting slow at the grey apple logo screen to not booting up at all. Is it a problem with my hard drive? I also have boot camp running as well, but I can still see the boot camp drive for windows and my OS X drive, as well as my installation disk when I have it inserted when I hold the option key at start up.
    I'm still able to run windows on it without any problems when I pick the windows drive. I tried different methods from different forums but I'm just not getting through. I tried holding 'c' to boot up from cd and I let it run over night but it never got past the grey apple screen with the gradient wheel (still spinning). I had already used time machine to back everything up before this happened since I was able to boot up properly (but slowly). Can anyone help? It's driving me nuts, and I can't remember what os/firmware version I'm running.

    n your signature you said you are running 10.6.3.  So let’s assume you are running Snow Leopard.
    It sounds like your diagnosis of disk problems is correct.  The OS X partition may be corrupt.
    Try booting in Safe Mode.
    http://support.apple.com/kb/HT1564
    Try again to boot in normal mode.
    If it will boot in Safe Mode but not in normal mode then you could have some 3rd-party software preventing the boot or you could have a corrupt disk or OS.
    Boot as from the startup manager (Boot - option) and then select the installation disk.
    Hopefully that will work better than starting with the Boot-C option.
    Then try to repair the system disk.
    Start the Disk Utility.
    Perform the steps in http://support.apple.com/kb/PH5836.
    If it repairs OK but still won’t boot reinstall OS X.
