My 2007 iMac is giving me fits. It will not come up after reboot. I have used Tech Tool 6 to boot up and after running tools, get a Validation Error in an Allocation File (bitmap).
I am running Mountain Lion but did not have a boot disk for that OS, so I used my Lion OS USB disk to access the disk utility. All efforts to repair failed.
I have a complete Time Machine backup on an external drive, but the restore option does not see it.
Any input would be appreciated
Terry
