I'm using Mac OS X 10.9.5. Parallel desk version 10.1.4. Windows7 stuck on update for a long time, I tried to quit but when I start it again, it's still updating. I tried searching prl_vm_app in Activity Monitor, but I can't find it. And this is the latest Mac console log about prl_vm_app. (Sorry it's very long but I don't know which part is crucial to the problem.
