Running Disk Utility from the OSX install CD to try to repair my startup hard drive, I got this message: "The operation couldn't be completed. (OSProductManagerDomain) error 100."
The problem that led me to repiar the hard drive was Time Machine was stuck forever in "Calculating Changes" and could no long make backups.
Any idea what to do next?
Thank you! Actually, I did finally get disk utility to start off the DVD and successfully repaired my internal start up hard drive (or so the disk utility report said), as per suggestions I've read in other discussions on this Time Machine problem.
But the problem remains: stuck on "calculating changes" permenantly. Haven't had a back up since Sept 5th. I'll call Apple tech today, but I'd love to be able to fix it myself and any suggestions are much appreciated.
