I had one of the early 2011 MacBook Pros that recently had the main GPU finally die, of course after Apple is no longer fixing them for free. Well, I found a thread that had instructions to disable the AMD GPU and force the Intel GPU. I had already bought the wife an All In One so she could still complete her school work and Pinterest. The Mac has an i7 in it and although notebooks heat up quick you can generally run 3 or 4 cores without issue. So I could attempt to get a couple hundred for it or... I could run BOINC!!!
Basically it would only boot for a few seconds in OS X or not at all in Windows/Bootcamp. After having to work some magic from a USB Linux boot and then installing Lion, removing drivers through terminal, installing Captain, removing drivers in terminal, then installing high Sierra and for the last time removing drivers in Terminal the machine will be online shortly. Let me also point out that during that process each time Terminal was needed took 3 - 5 reboots and attempts at loading into Recovery successfully.
While I did not really care if the machine ran again, I also took out the logic board and reapplied some thermal paste to the CPU.
I had never completed that on a Mac before, interesting stuff.
In the end, I have another machine to hammer some more CPU driven tasks.
