Opened up my Kali image this evening and ran an apt update && apt upgrade, and after reboot the screen is black. I have the latest version of Parallels 15 and the most recent toolbox; I also have the grub fix installed for the video drivers issue for Kali. I have disabled 3D acceleration and have also toggled the grub fix on and off (neither made a difference). I am running Kali Release 2019.4 (5.2.0-kali3-amd64). What other type of information is needed to troubleshoot, is there something else I should be looking at and should I open a support ticket? Figured I'd start here, in case someone else has the same issue.
