My Macbook Pro (15 w/Retina, 2012) keeps blacking out on me. The computer doesn't fully shutdown, but the screen goes black. What does this mean?

About a month ago my fan started making a weird clicking/whirring noise. It eventually stopped and I thought nothing of it (this might be unrelated, but I just want you all to have as much info as possible).
Then, yesterday, my Mac was acting funny. I was trying to watch netflix and whenever I clicked on a video, BAM the whole screen went black and the sound stopped. But the keyboard stayed lit. The only way to rouse the computer out of this state was to hard shut it off (ten seconds on the power button), and then turn it back on. Except, sometimes when I turned it back on, the screen would go white and play the mac startup musc and then immediately go black again. It was really weird and took me 2-3 times to be successful with even booting up the computer.
I ran a hardware check and it said nothing was wrong. I tried to reinstall the OS but when I entered recovery mode, the internet just wouldn't work. Like... the wi fi found no networks, even though I'm sitting in the exact same spot I was in yesterdat with the entire wi-fi wave filled and it's totally fine.
I don't know what this means. I'm planning on taking my mac in tomorrow, but I was wondering if you guys could help save me some time.
Here's what my most recent error report looked like:

Also really quickly: I don't know where to put this, but the first time my computer reset, the desktop wallpaper turned back to the wallpaper I had before the one I currently have selected. That was really weird/random. Thoughts?

It looks as if there's a problem with your GPU. With a Retina machine, that would mean replacement of just about everything, except, perhaps, the flash storage drive.
Print you kernel panic when you go to your Apple Store appointment. I'm betting that it's a faulty GPU but they will be able to diagnose exactly where the problem lies.
Good luck,
Clinton

  • Why won't my MacBook Pro backup to Time Machine (on my 1TB Time Capsule) when I'm running Lion OSX 10.7.5.? What does it mean when this error pops up: MacBook Pro.sparse bundle could not be assessed (error - 1).???? Please help me fix this!

    Apparently I am not the only person having this problem as I have seen many threads about it. If ANYONE OUT THERE CAN HELP ME, I WOULD SINCERELY APPRECIATE IT.
    I try and run my backup as I always have, but it HAS NEVER COMPLETED SINCE I UPGRADED TO LION. As many mentions, I updated from 10.7.4 to 10.7.5 hoping that would fix my issue and it didn't help at all. I also unistalled WD SmartWare to no avail. It's really starting to annoy me since I have as much money invested in my MacBook Pro and Time Capsule as I do in my car....
    I have more than enough space on the Time Capsule, but Time Machine is still failing and coming up with an error message: MacBook Pro.sparsebundle could not be assessed (error - 1).

    Yes, the website works fine on my PC computer.
    It was working fine on my iPad too until the message showed up. The website took a long time to load and when it finally did.. That message showed up twice. The site works now but at times will stop loading.
    I do feel like my Internet connection on my iPad is spotty today. One minute it is loading super fast, the next, the page won't load at all. Could be my connection though.
    I do not have the debug console set to on. Should I set it to on?

  • When I'm trying to sync my iPad with iTunes on my MacBook Pro, i keep getting a message that certain recent purchases (TV shows) won't sync because the computer is not authorized.  But, it IS authorized!  What's going on here??

    I've recently upgraded my iPad to OS 5 and I am running iTunes 10 on my MacBook Pro.  For some unexplainable reason, I'm now getting a message that items (mainly TV shows I've purchased through iTunes) are not able to be downloaded because the computer is "not authorized."  But the computer IS authorized.  I follow the instructions to "authorize" it and, of course, I'm then told that the computer is already authorized!  Still, the downloads won't sync.
    Can anyone help me out with this?

    I have the same problem. It is only with tv shows and only with programs I have downloaded after the software update.
    Apple support sent me the above link too....but it doesn't solve the problem...my computer is authorized and the content is in my library and will play on my Mac air, but it will not sync the tv shows, it keeps saying my computer isn't authorized for it.
    No answers here, but you are definitely not alone with this issue.

    My macbook pro displays a folder with a question mark and won't open. What does this mean and how can I fix it?

    it means your HD and the software can't find each other, the following article tells how to troubleshoot this issue:
    https://support.apple.com/kb/TS1440
    hopefully you have backup of your data since sometimes this means the HD is crashing.
    if the article doesn't resolve the issue i would take the mac to apple store or service provider and have it looked at, the following link tells how to find one close to you:

  • The battery icon on my (old) MacBook Pro turned red. Then black. What does this mean?

    The battery icon on my (old) MacBook Pro turned red for a few moments, then black. What does this mean?

    penny41,
    Thanks, glad it helped you to check your battery status.
    Something else to look at would be the cycle count, as you mention that your computer is "ancient". If you have a high number of cycles, it may also be a sign that the battery is tired and possibly nearing it's life span, and may possibly need to be replaced soon. If you see that again you may try a SMC reset to see if that helps, but if it continues you may need a new battery at some point. The battery icon will usually say needs service, or something to that effect.  For the later MBP's Apple claims a life span of up to 1000 cycles, of this also will be dependent on who the battery is used, on the older ones I'm not quite sure what the claims were, and I don't know how old "ancient" in your case actually means.
    I provide this for your info, so that you understand what may possibly be occurring.
    I wish you the best.
    SMC reset:
    Follow directions for what applies to your machine, a battery you can remove, or a battery you should not remove yourself.

    This means that the backups were made with a later version than the version currently on the phone. You will have to update the phone to 6.1.3 to be able to restore the backup. You can restore a backup made with an earlier version, but not with a later version.

    I've deleted all large files and apps that were taking up room. My computer is down to the bare minimum now.
    Any help would be appreciated.

    Have you already verified/repaired the hard disk with Disk Utility? If not, do so.

  • Burning playlists from my iTunes to CD doesn't work anymore. Keep getting a "medium write error" message.  What does this mean?

    I'm trying to burn playlists onto a cd from itunes.  I keep getting a "medium write error" message.  What does this mean?  I heard that this may mean that I should try burning at a slower speed.  I tried this and that didn't help.  I also heard that I may need to use a different brand of CD-R disc.  I have not tried this yet.  I also heard that it could be a software issue or disc drive issue.  I recently updated my macbook pro software from tiger to snow leapord.  Do you think this could have affected my itunes playlist burning capabilities?  Thanks for the help.

    A system upgrade should not have affected anything. When did you notice the loss in functionality?

    Realize that a MBP that came with Tiger is an old computer and optical drives do not last forever.
    You could try a drive cleaning disc to remove dust.  Don't be overly optimistic. I suspect it is an old drive issue.

  • When i try to log into my app store and iTunes and the message keeps coming up saying review your account what does this mean and what should i do

    i just got my mac book pro and i am trying to log into my app store and iTunes and i try to log in and it keeps saying you need to review your account what does this mean and what should i do

    Please provide the full text of the message and describe at which point in the login progress it is displayed.
    In the meantime, make sure you're logging in with the same Apple ID and that the new computer is authorized with that iTunes account.

    My MacBook has a grey screen with a folder and a question mark in the middle what does this mean?

    It means a valid system cannot be found. You need to reinstall OS X.
    If you have Snow Leopard:
    Reinstall OS X without erasing the drive
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    If you have Lion or later:
    Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
    Reinstall Mountain Lion or Mavericks
    OS X Mavericks- Reinstall OS X
    OS X Mountain Lion- Reinstall OS X
    OS X Lion- Reinstall Mac OS X
         Note: You will need an active Internet connection. I suggest using Ethernet
                     if possible because it is three times faster than wireless.

    The last date of my back up was 10/4- keeps saying The backup disk image "/backup disk image "/Volumes/time Capsule/ cheryl lynott's MacBook.sparsebundle" is already in use?

    Often, this error can be corrected by pulling the power on the Time Capsule, waiting a few minutes, and powering the Time Capsule back up.
