I have quite a "few" macs that are plagued with the Nivida and ATI graphics that are well known to fail as you will read
So I have a 2011 iMac 2011 27in with the I7 2600 and 1Gb HD 6970 ticking time bomb. I got this from work since the drive has 90 failed sectors but I been using it daily and its works fine (thats a whole other issue I'm going to have to deal with later on). I have had many MacBook Pros with the 8600m GT quit on me ( 2 CTO 15in and 1 CTO 17in died on me both with less then a year of usage on them, only 2 others I have survived this plague). I have 2 early 2011 MacBook Pros one base 2.0Ghz i7 15in, and one CTO 17in. I recently got the 2011 CTO 17in back to life when, originally it was thrown out due to water damage 3 years ago (works great now!!!!). The 2011 15in had graphics issues within the first year we had it (in 2011) when apple denied our warranty claim we left it to rot with our other macs until I decided to boot it and its magically working as if nothing happened. Haven't used it to much since it needs a new battery the original exploded while in storage and cracked the trackpad.
What this post is about is I just wanted to ask other owner of these years Mac products and have them post about issues with their 2011s since I'm quite worried about my iMac quitting on me soon since its getting older now. I use it for the web and Netflix and thats about it
. I play some Steam games on it (rarely) but when I do I max all the fans to try and keep everything cool.
If you have (or had) a 2011 MacBook or iMac with ATI dedicated graphics problems was there really any warning signs to the GPU failing other then the screen going purple or random bars showing up and the images on screen distorting?
Have you done anything to try and extend the life of your 2011 Mac with ATI graphics?
