So i run disk utility and i found out that i have lots of different permissions. So i clicked repair permissions. It doesn't matter how many times i do it. They keep appearing. One of them has to do with iTunes. For example when a song is playing,i have set it up to show the whole time of the track. But everytime i launch the app it shows how much time is left counting backwards. This is getting really annoying. I've tried repairing them with Onyx but it doesn't work either. I have the latest OsX(10.5.6) and 55.71 free space from185GB (i don't know if this matters. My MBP freezes a lot and generally it runs very very slow). Any suggestions please??
