ditto to Robert Brown’s comment. I have a 2.53 ghz macbook pro i5 that I used the CUDA “hack” (see link below) on to get the video card usable by CUDA. Much faster, but had this issue – then turned it off, and bam!
Also did all the permissions / disk utility / uninstall&reinstall / disk change / pref dump deal without it helping.
Hey, at least it is a quick fix eh? Hoping this works better in AE.
