I am running a kali guest with Parallels Desktop Pro 13 on a MacBook Pro with High Sierra 10.13.4. Everything has been working very well for more than a year. However, when I attempted to update Kali a couple of days ago, the VM will no longer load. I get to the kali boot screen then nothing. I can revert to a snapshot I made on March 29 and everything works fine again but updating breaks it. Any suggestions?
