I have the newest version of Parallels 14 I have had many times where the system would just lock up. I have gone through and checked the disk, etc. I read the forums and they say that Parallels is better but Fusion seems to be more stable. For example, today I couldn't even start Parallels, yes I rebooted, and did the activity monitor thing. I just couldn't get win 10 to run so I wanted to see if something else might be causing it. I turned on Isolation and it booted without a problem. It also had no problems. Running stable, no processor issues, or lockups so far. Is it possible there is an incompatibility with One drive for Mac, Google Drive, Team Drive, Dropbox? Does anyone else use these without a problem? Thinking about going back to Fusion just for the stability.
