    Weird GPU temperature behaviour on iMac (late 2014) with macOS 10.15

    Lately (maybe over the last year or so) the machine has started spontaneously entering sleep mode now and then during use. This is during non-gaming use, even while just web surfing, but more easily reproduced when doing things like viewing Google Maps in 3D. (Plus whatever macOS might be doing...

    With NVIDIA releasing their 3000 line of cards just a few days ago and AMD supposedly releasing their Big Navi RDNA2 chips later this year, I was wondering if Apple will refresh the GPU option on the iMac 2020 one last time. Apple has done such a move before in the past with the iMac Pro. On...
