Please refer an authorized staff member here. I bought and installed Parallels for Mac 11 on a MacBook Pro (Retina, 13 in, Early 2015) Running 10.5.5. Everything went fine for about a day, but now every time I try to end a session of Parallels (not a specific Win application), my MabBook freeze and show a kernel panic screen. Please help. Elad
Please repair Disk permissions in the Finder -> Applications -> Utilities -> Disk utilities. Also if this kernel panic reoccurs please generate the problem report right after that and provide us with the report number.
