13" MBP 2012 freeze, HD4000 graphics to blame?
I bought my 13" MBP (2012) two days ago and have tried running a few programs that push the graphics capabilities. I know the 13" has no discrete GPU, but did not think that running graphics-intensive tasks would freeze the entire system, requiring a forced shutdown (holding power button for 5 seconds).
The two most recent freezes were running X-Plane. After the first freeze, I set up a program called Temperature Monitor and saw that after X-Plane loaded and started playing, the GPU diode had gone past 103°C. I quit X-Plane and it started cooling off, but the system froze the second time after it reached 92°C.
Other freeze include Chrome using its built-in Flash to run the "Scale of the universe 2" interactive animation (GPU temperature doesn't seem to go above 70°C when doing this), and in Safari when checking out Google Maps' new WebGL features.
Unfortunately there are no crash or kernel panic logs for any of these.
On my old white MacBook (late 2006), when the CPU temperature rises above 80C, e.g. when trying to play some (but not all) HD videos, there will be audio and visual stutters, at which point I stop doing what I was doing.
Is there not some kind of failsafe in OSX or the video driver that chokes the GPU when it exceeds a certain temperature? If not, how are we to supposed to know when something will spike the GPU? There is no warning to *not* run games or graphics program just because it has no discrete GPU.
