Hi I have been having problems with iCal for a while and have also been unable to launch Logic (it seems to freeze when it is initializing Core Audio). I added a test user on my MBP and logged out of my account and Logic opens up fine. So far I have had no iCal problems. I have tried repairing permissions... Can anyone help me out? Or how to I easily create a new user that looks exactly the same as what I have now (minus the iCal and Logic problems). Thanks!
