Hi there,
had also an issue with Spotlight not indexing on my MBP after the OS X 10.7.5 update. At first I noticed that new files did not make it into the index - initiated re-indexing for a cure but Spotlight got stuck and showed up to 4 years remaining (screenshot).
My other Mac (2008 MacPro) did not have the issue following the 10.7.5 update.
I tried the following:
- verified and repaired drive
- repaired permissions
- removed index again and again ...
All the above did not solve the issue.
Solution on my MBP (it seems):
This morning I decided to reinstall OS X through Lion Recovery (Command-R during reboot) - obviously with a backup in place. Good news after completion of the installation: User accounts, applications and data all survived the reinstall.
The Spotlight issues seems fixed now - I got past the Spotlight 'estimation' process very quickly - a reasonable 40 minutes of indexing time remaining. Do hope it will complete successfully ....
Damage following 10.7.5 was not limited to Spotlight ...
Still left with Aperture broken on both of my Macs! Not sure if it was due to the new Aperture 3.4 release, the OS X update or the combination of both of them - grrrr. Will have a look tomorrow.
