(1st answer) - carefully executed a number of commands, calculated a sizelimit for my parition layout, and finally ran sudo mount -t hfsplus -o force,rw,sizelimit=YOURNUMBER /dev/sdb2 /mnt to mount this HFS+ partition to /mnt directory in read-write mode.

In my case it was even more difficult because the OS X partition became a 'read-only' partition (because of too many emergency shutdowns I did while desperately trying to boot OS X with a failed GPU) so I had to remove a hard drive from MacBook Pro and (using a USB to SATA 2.5' adapter taken from my portable HDD) attached it to a computer with Linux, then followed these instructions: The degree of your inconvenience while doing these steps - strongly depends on how heavily a screen's image is distorted in your case.

But I don't like investing money to the old computers, so I have thought - what if there is some hack to force MBP to use integrated graphics ALL THE TIME, even while booting ? And then started to explore the possible solutions.įirst of all, it is possible to successfully boot a MBP to OS X while still using the failed GPU, after you remove the AMD drivers by booting in command line mode ( CMD+S) and entering these commands:Ģ) mount -uw / (mount a root filesystem with read/write permissions)ģ) sudo mkdir /AMD_Kexts/ (make a directory to store the AMD drivers in case you'll need them in future)Ĥ) sudo mv /System/Library/Extensions/AMD*.* /AMD_Kexts/ (move the AMD drivers)ĥ) sudo rm -rf /System/Library/Caches// (remove the AMD drivers cache)Ħ) sudo mkdir /System/Library/Caches// (just in case OS X will be dumb and will not recreate this directory, I am creating it for OS X)ħ) sudo touch /System/Library/Extensions/ (to update the timestamps so that new driver caches - without AMD drivers - will be definitely rebuilt)Ĩ) sudo umount / (umount a partition to guarantee that your changes are flushed to it)

But it finally broke down last week: laptop's screen image became distorted, it refused to boot OS X (always freezing half-way), and - Apple free repair program has already ended! I know there are affordable solutions like $50 BGA resoldering at unofficial local repair shop and that its possible to get a new replacement HD 6750M chip from AliExpress for $35 or cheaper ( ) to guarantee a successful repair, so the total price of repair would be either $50 or $50+$35=$85 - less than $100 in any case.

It has been working perfectly for 6 years under quite a high load, even tried mining at background! So I was confident that my MBP is not affected by bad solder / bad soldering quality and didn't want to bring it to Apple for a free repair program - partially because couldn't find the time to pause my important software projects, partially because I was afraid that Apple might give me a less reliable logic board or refuse a free repair because of the several unrelated repairs that I did manually by myself earlier to save money: changed thermal paste a few times, replaced the internal battery 2 times, replaced a keyboard with broken buttons, etc. If you don't have time to read my story (which also describes some interesting technical approaches) just scroll down this thread until a '100% WORKING SOLUTION' textĭiscrete AMD GPU of my 2011 MacBook Pro 8,2 has finally failed because of the reasons mentioned here ( ) and there ( ).
