I am having all kinds of issues with this setup. Parallels locks up all the time. I can't close it down and I am forced to reboot. I am also seeing spontaneous exits from my OSX login, where it logs me off. This one I am not sure if it is Yosemite or P10. Right now I wish I didn't upgrade. Maverick with P9 was working really well. Any others experiencing this? Any help remediating this would be much appreciated.
