I don't ask for much out of my Mac Mini and MacBook except to be able to stream my iTunes content from my mini to my Mac Book at night. Since iTunes got updated and I was dumb enough to put High Sierra on both of these devices this use case has completely become flaky. Every night I have to restart iTunes. Sometimes no matter what it just doesn't work. It isn't just my MaBook having issues streaming iTunes content. The Apple TV 4 doesn't work at all with iTunes streaming any more. This is the type of thing that is like nails on a chalk board for me. The lack of testing and breaking of the integration between devices is enough for me to look at other devices for content on the TV. It's enough for me to say I'm not buying another Mac ever. Which is fine because their computers are over priced for the hardware anyways and Tim seems to like soldering everything on. Good job Tim. You took a long time fan of Apple and in 7 short years you have converted me to anything but Apple. So much for High Sierra being about making it as stable as the days of Snow Leopard. Steve must be rolling in his grave.
