Yes, Eric ....it is my husband's machine that is giving us grief. We uninstalled CleanMyMac ....did not solve the auto-play problem. So I downloaded the Amazon Music app on his computer ...works great. Now he can listen to his music while he works.
Booting up still takes a minute and a half ....but I think the problem probably lies in the two users on that machine. The story of how that happened it WAY too long, and not worth the effort. Both users are Admin, and it looks like they are playing nicely and sharing his important programs. However, I believe it just takes a while for the computer to sort that out as it boots up.
Any further thoughts on that ....or should we just turn it on and get coffee?
