The operation can’t be completed because you don’t have the necessary permission.
I am trying to create a new folder on my desktop, but this message pops up: The operation can't be completed because you don't have the necessary permission.
I am the sole owner and user of this Mac, and bought it at the end of last year. Up until about 4 weeks ago, I hadn't encountered this problem before. Any possible solutions to my problem?
iMac, Mac OS X (10.6.7)
