My refurbed Mac Pro (mid-2010 5.1) is amazing ..... except for a huge problem I am experiencing where when I drag files from one folder to another, I get a freeze requiring a restart. I can drag a folder no problem...and I can drag audio files into Pro Tools no problem...but something is freaking out the computer when I try to drag multiple files at once. I have looked online for any tips, tried what I saw, but no luck. I'm running the latest version of Mojave. Anyone experienced this issue and find a solution? Thanks!
