Following all the issues we've been going through on the the http://forums.macrumors.com/threads/mac-pro-late-2013-gpu-driver-issues.1860297/ thread. Is anyone running a 2013 Mac Pro on Yosemite 10.10.3 with no issues at all? My issues are: GPU Panic / GPU reset when using Photos / Final Cut Pro X / iTunes Regular boot problems (despite doing full erase and install) - possibly linked to private/var/db/displaypolicyd issue reported elsewhere For me 10.10.3 has been the most buggy useless piece of Apple software I've used since troubleshooting extension conflicts on Classic v9!! Is this just a bad unit (this is my second this year!!) or are we all struggling with 10.10.3 ?
