![]() 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 ( or, because don't know if this is true - ) 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 ( ). I wold dare to ask you a question or maybe twoĭo you recommend me to turn on Filevault on this Macbook Pro Late 2011?ĭo you recommend to upgrade to MacOS High Sierra(that just purely because i want to use this system options, like iCloud.)? Like i said earlier, i followed your steps and everything look fine for me now, I'm on El Capitan with FileVault not active, just purely because i didn't set this option on Lion(the OS i get from cmd+opt+R(i think, I'm not 100%sure)). I get this macbook pro late 2011 like a gift, I've been happy with for a long time, but after i upgraded to MacOS Sierra, everything get worst, starting with slowdowns, ending with grey screen on booting. I will go with you in a long story short way into my situation: I just installed your app, and am at home, unable to test it fully.In the first instance i would like to thank you for your post, i read everything and after few time trying i succeed to have my macbook pro late 2011 back to life. As far as I can tell, the app does permit power-source-based switching without the login display resolution problem! I have to test the effects on an external projector display next week when I'm in a classroom, however it may limit the resolution available to me when running on battery power and connecting a projector. This application allows me to choose the card to use when I want to save battery power and have no external display connected.īut it resets automatic switching if it was turned off before the app was run. This seems to be an Apple bug triggered by some update in the past couple of months, at least on my MBP. You can't get back the highest resolution and have black bars at the top and bottom of the screen (the higher resolution setting is not available on the integrated card, and for some reason the system won't permit the change). On some Macs with dual cards, such as my 2011 MBP, use of the Energy Saver automatic graphics switching will trigger a display problem when logging out and logging back in: the display will be stuck on a lower-resolution option until restart.
