I've seen threads on this but there were mixed opinions. I have the Apogee Duet and a MacBook Pro. I've seen all of the problems that people are having with this combo as well... Thank God I don't have those problems so far. I think that is because I have the Texas Instruments FW chipset and I'm still running Tiger. The people that were having the problems seemed to be those with some new chipset(the manufacturer escapes me right now) and they were running Leopard. My question remains. I have not had a problem either way but I've seen one post in particular where the guy was adamant about NOT hot-plugging it. Even though I have not had a problem, I don't want to do something that will reduce the life of either my MBP or the Duet. Does anybody know and have data to back it up? Thankss.
