Every time I try to update to 10.5.2 update on my C2D MacBook the status window hangs on the "Configuring Installation". I've tried multiple times with no avail. I also tried verifying/repairing persmissions, but that didn't work either. Any ideas? I'm not entirely against doing a reformat, I've been thinking about doing one to get rid of the junk I don't need. However, if it can be avoided, thats great. Thank you in advance.
