Random freezes on Mac

Update: I tried a clean install. Still the same freezes at random moments.

I can confirm that the fan starts working at full speed about 5-10 seconds before a freeze. This leads me to think it may be GPU-related?

disable scaling, I'm seeing the same "Shader failed" on scaling as the nvidia win 10 error o.o

It updated to TB-247630 this morning, and the problem is gone. I've been able to play both new and saved games through several cycles without the freeze.

Which is not to say it's running perfectly- the sound still lags/cuts out/stutters, and very occasionally it will freeze when I right-click-drag the screen. But it's playable now.

it has returned- although not as frequently as before TB-247630.

I have attached the log and a list of processes ONI was running at the time of the freeze.
