Deleting Preference Files List On Leopard 10.5?


Distinguished Member
Hi All!

I have a June 2009 17" 2.8 UMBP which has been driving me mad with near constant beach balls! I run no intensive programmes at all - just emails & surfing the net!

I originally used migration assistant from a Tiger MBP to this one & read that I may have corrupted Tiger P-Lists transferred over to my Leopard One. I would like to ask, how can I get rid of/delete my current preferences list to see if that fixes the problem - it did with another person who also transferred from Tiger to Leopard with Migration Assistant!

I am a novice so please treat me like a 4 year old who needs very step by step instructions!

Many Thanks All,

The easiest way to test to see if it is your user preferences is just to make a new user. This way you won't delete anything important. If you still get the constant beach balls with the new user then it may be a system wide problem.

To create a new user open system preferences and go to Accounts and then click the + button.

After creating the new user log out of your current user and then log in with the new one that you just created.

Then just test all of your programs that you're having trouble with.

See how that goes and if you don't have issues with your new user you could either just use your that user or go back to your old user and then try deleting preferences etc. (Post again if that's what you end up wanting to do)
