I discovered a problem: When a Windows 10 (with latest updates) runs in Parallels, and I start a Office 365 application (Word, OneNote, etc....), then the screen freezes for some seconds and the Mac crashes, which means the Mac makes a reboot. I am very sure, this crash only happens because of Office 365. My configuration: Mac mini 2018 with 32GB, with eGPU ASUS XG Station Pro with Radeon Rx 580. I made a clean install with Catalina, using Parallels 15 with latest updates, using in Parallels Windows 10 with latest updates. Does anybody have the same problem? Does anybody know how to solve it? Beside that: Parallels on Mac runs very stable with Windows 10!
