Anyhow Thanks for your reply!

A few things:

- my iMac has a Fusiondrive 3TB (I'll add this to my signature, you're right about that) this drive is divided in two partitions HD-system and a Data partition. (on a Fusiondrive, you're allowed to make one extra partition)
- I've made for safety reasons a bootable copy of my internal HD-system-drive to an external drive, with CCC (carbon copy cloner).
- the first time the problem occurred was after cloning. The problem was solved by booting once from the external drive.
- Everything was fine for a few weeks, so I thought the problem was caused by CCC. But than without changing anything or any other obvious cause the problem reoccurred. The problem was also fixed again by booting once from the external drive and than reboot from my internal drive.
- what is remarkable, that it only affects PT11. All other applications including PT10 don't have this problem.

So maybe it is a specific problem from PT11 in combination with the Fusiondrive of an iMac. That would be interesting. And maybe helpfull for Avid and other users.

Like I said you may be having a problem with your internal drive. Do the repair permissions and then verify the drive and see if that puts up any errors. Remember with a Fusion drive you as the end user only have access (without messing around in Terminal) to the spinning part of the drive as OSX takes care of what goes where. Just because you did another partition to the Fusion drive doesn't mean you can use it to record to in PT - you still need a separate dedicated non-green drive.

That being said it could well be a problem with the combo of PT11 and the Fusion drive.
