Are there concerns amongst these companies about the lack of hardware updates to products like this by Apple? What hardware are these companies using at the moment? iMac Pros? And before that they were using 2013 Mac Pros? I think there was a 4 year gap between those products I think? I'm surprised that more companies in industries that use this type of hardware haven't left the apple ecosystem. I have a home recording studio, so I have some desire for good hardware but I can get away with a regular iMac. It's hard for me to have perspective on this stuff.
