iMac + Midi problem

Merry Xmas everyone!

Was looking forward spending my xmas alone in my studio recording some new tunes but cant get my sound to work on my new iMac, so now I have to spend some time with the family

Would be really helpful if someone could help out.

Got the new (mid 2011) iMac 27inch 3,1Ghz. Apogee duet 2.

Ive always used M-Audio Keyrig 49 on my previous mac with no problems.

I get the audio output to work fine via the Apogee duet but the midi which is USB bound works for up to 10 seconds and then freeze on a note, I have to restart and then it works again.

Ive tried the following:

- on different softwares (Reason and Logic)
- change cables
- use a midi monitor software (it identifies Keyrig)
- changing USB ports
- If I reset all midi devices in Logic the keyrig works again but after 10 seconds of playing freeze on a note

Im going sligtly insane.

Help please

 

Thanks! Will do!

Thanks!
