After an alert asked if I wanted to apply a minor update to Parallels Desktop for Mac, it would no longer boot my virtual Mountain Lion, although Windows 10 boots just fine. Even a fresh, new virtual machine I create with Mountain Lion seems to install, but then won't boot. I get the errors in the attached image, then it continually retries to start. I'm running El Capitan on a 2012 27" iMac. Has this happened to anyone else? I had a remote session with Parallels last night and the technician sent it up to a higher level to figure out. I'm waiting for the next round of tests.
