three VMs that run fine on newer machines all crash on Catalina on my MacBook Pro 2015 15" machine.
i7 chip, 16gb RAM, mid 2015.
They run for a few minutes, then the screen starts flashing, goes blank, changes to blue and black, then just flashes until I power the Mac down.
This is true for all three of my VMs -- a Catalina, a Windows 10 and an Ubuntu, all of which run fine on a MacBook pro 2017 13" and a MacBook pro 2019 16".
