Before you update from 10.10.2 to 10.10.4, check out the problems on iMovie crashing first, both version 9.0.9 and 10.0.9 don’t work. would wait until the problem is fixed – especially for HD4400 graphic card from Intel. I restored the 10.10.2 and everything works perfectly, if it works, don’t fix it.
It’s the OPENCL that doesn’t work.
Tested with HD4000 IvyBridge is working perfectly.
