Since the beginning my Mac Pro have had problems with my external gear. I have a lot of external stuff connected both to USB and Thunderbolt ports (3 midi controllers, audio interface, a couple of discs, three displays). I have always had some problems with the external stuff, but since I got a new midi controller with own software on it, its worse than ever. Almost every thing I have connected to my mac pro has their own power supply, (except for one SSD disc and a Midi keyboard that runs on 6v 1A power) so I guess its not a power supply issue. any one else with these problems? discs that suddenly says its not connected (and the mess "didn't eject properly..." comes up), my midi controllers that sometimes blinks and resetting the software without saving it etc... one in three times one of my three screens won't start when starting OS, and I need to restart the computer. I have done two major OS updates and these issues is still there (I have everything updated to the latest firmware). I should say that I have a lot of issues with logic pro as well... Plugins that does not work as they should (several of them), and YES I bought every plugin I use... thought it would make things work better. Some arrange I can't even open anymore in logic. These are problems I haven't heard ANYONE of my friends have (they don't have a Mac Pro, but Macbook pro and Imac. Am I just "unlucky" and got a bad ex of mac pro?
