Yesterday I installed 10.3.6 on a 17" AlBook via Software Update. While the download/install appeared to go ok, on restart the machine shows the circling icon from disk checking. But the disk check never stops. I let it run for a while, then rebooted; let it run for a couple hours, turned it off, let it sit for a while and then tried letting it run overnight. Same result: endless circling.
This morning I mounted it to a 15" in target disk mode. I did Repair and it said successfully repaired; no repairs were noted however. I did notice one anomaly: on my 15" it indicates "Permissions enabled: Yes" ; on the 17" it says "Permissions enabled: No". The option to repair permissions was greyed out.
What should I do next?
Thanks in advance for your help.
