Hi Ronni The end of the saga is in sight, I hope. The 2009 iMac now starts up and is workable. Disk Warrior was used to create a new directory, but there are some files in the Rescued Items folder. There are a number of other things to be checked and apps re-installed. Before Disk Warrior was applied, you suggested booting from the Recovery Disk and to Repair Disk and Permissions via Disk Utility. You then said to Reinstall Mavericks (via the Recovery Disk Utilities).
When should Mavericks be re-installed? Now, before I attempt to fix the remaining issues left by Disk Warrior and a possible corrupt OS X?
