Hi, I currently have some issues with my Mac and Parallels. The issue is when I want to open Parallels there's just a spinning pinwheel that just keeps spinning. Sometimes I get through and can start Windows 8.1. I've tried a lot of times and the times when Parallels / Windows actually starts it just hangs or my Mac gets so slow that I have to do a hard-restart from the On/Off-switch. I got Parallels to work 2 times and at those times I've tried to "Free memory" from Parallels Toolbox but without any further progress. I need Windows to work since I work with e identification that only works with Windows.
