Is reset PRAM still a thing ???. I used to have a Mac Pro (cheesegrater) but switched back about 2 years ago due to having a kid in college and Dell and Windows 10 were not too shabby. Probably on my 4th Windows 10 release from the original that Dell shipped with and it has been rather stable system.
