Exactly. Sierra was bad enough requiring a bunch of expensive software upgrades (vmware). There hasn't been any difference in os x in years. My MacBook Pro never slept properly and needs to be hard booted in all of the four past os x releases so there's no need to upgrade even to get the bugs. I wonder if I'll ever own a laptop that sleeps properly, but at this point I doubt that just like I doubt anyone can write a proper file system sync between host and guest vms. I guess some things are just impossible to solve yet, but I'm sure ai will solve all of this in two weeks once it takes over, except Apple's quality problems which seem intractable. /s
