Noticed Parallels has become much slower, in fact downright sluggish in starting up the virtual machine on my Macbook Pro (16GB split 8GB OS 14, 8GB Windows 10). Used to be pretty quick (30 seconds or less) but now it can take 2-3 minutes. Running Ver. 16 Parallels. It eventually fires up, but something has gone wrong. If this persists, I'm an ex-user of the software.
