iMovie, Final Cut Pro X Trial crash

iMovie, Final Cut Pro X Trial always crash, random QuickTime crash

I am running into iMovie, Final Cut Pro X crashes on Yosemite 10.10.1. iMove and Final Cut Pro X can be open but once I am trying to load any media file, the app will crash. I also got random QuickTime Player crash as well.

Crash report attached.

Thanks,

I just solved the problem myself. After switching smbios product definition (using Multibeast) from iMac14.2 to MacPro6.1, I don't see crashes any more.
So, if you ever run into problem like this, especially see the following in crash report, try to play with system definition.
