Apple macbook pro 2011 not booting up all the way
That is why the issue is hard to pin down because it masquerades as something else. So when the GPU freaks out, it freaks out the main logic board. The faulty GPU is integrated with the motherboard. The cause was a faulty GPU, the subject of a recall which unfortunately was over in December. I went through the same agony over the past few months. Im a little hopeless at this point, just wanted to see what the Internet turns up. IF I'm missing anything, let me know and I'll tell you my results. I'm taking it in anyway to see if they'll repair it. MY problems don't exactly match the symptoms listed for the known video processing problem for my computer. I plug in that hard drive with the os installer, and run it. All subsequent first aids return no problems. First run of first aid reports a problem discovered with the partition map. I launch disk utility as soon as my applications will load. Goes black again, goes back to blurred background and then. Color on the screen, a blurred out version of my usual desktop background. After a few seconds, screen goes blank, then a spinning color wheel of death appears in the upper-left corner. Apple logo and progress bar, at the same spot, reappear, w/o the distorted bar. Then, a single distorted-looking horizontal bar across the upper 3rd of my screen for a few seconds. Just now, trying to boot up normally: boot-up chime, apple logo, progress bar got about half way. Hasnt done anything for me yet this time around.Īpple hardware test, normal and extensive, turns up no problems. That was how I was able to reinstall OS X the first time this happened like 3 weeks ago. ZApping the PRAM or V?RAM sometimes yields different results. Selecting the bootable drive either yields the same result as booting normally or in safe mode. Verbose mode: it gets stuck at different points.īooting from a bootable external usb hard drive with El Capitan installer: starting holding option brings up the boot disk selection, the Macintosh HD is always available, and about the half the time the external drive appears. Single-User Mode: fsck command tells me everything's normal. A little number that starts at 0:1 appears, gets up to about 0:5 as the bar fills, and when it does. After about s minute, I enter my wifi network and password, and a progress bar begins. Internet recovery mode: I get a spinning globe, and a message that says it may take a while. When I boot into recovery mode: Exact same as normal mode. Then the logo and bar disappear, leaving a blank screen forever. When I boot into safe mode: Boot-up chime, progress bar, but this time it inches pat the 2/3 mark, and ever so slowly fills to the end. It doesn't shut down or restart, and no strange lines appear on the screen. The bar gets to about 2/3 of the way across, and stops. When I boot normally: I get a boot-up chime, the apple logo appears with a progress bar underneath. I don't remember if I actually updated to 10.11.6, but I definitely had at least 10.11.5.

It has baseline-for-its-time specs: 2.0 ghz i7 w/ 6 mb shared 元 cache, 4 gb ddr3l 1333 mhz ram, 500 gb hhd, AMD Radeon HD 6490M graphics processor with 256MB of GDDR5 memory, Intel HD Graphics 3000 with 384MB of DDR3 SDRAM shared with main memory (graphics switching), shipped with Mac OS X 10.6 Snow Leopard. I'll include every detail I can think to include, and describe what happens every time I try a solution that's been suggested to someone else. This is not a new problem, but I have scoured the depths of the Apple support community and others, and haven't found a solution that has worked for me, nor confirmation that my problem is what I hope it is.
