I recently turned on FileVault and encrypted my boot drive. I'm on 10.11.5 with a retina iMac. Since then, I've been having several problems that I wasn't having before, including: Crashes when the computer goes to sleep, or wakes from sleep; I have to hold the power button down on the back of the iMac to restart Crashes on restart. When I do maintenance and the computer is supposed to restart, it shuts down instead Problems with drag and drop and other mouse/tablet input issues Has anyone else experienced this? I'd like to have FileVault on, but this is seriously interfering with my work.
