Ok, so if like me you thought Lion 10.7 was a good idea and decided to upgrade only to find everything horrendously slow and unusable? Photoshop is a complete dog! I have a few tricks that may give the power back to your system.

1) ZAP PRAM http://support.apple.com/kb/ht1379
2) RESET SMC http://support.apple.com/kb/ht3964
3) Turn off Safari extensions
4) Repair permissions in the Disk Utility App
5) Reboot, hold down “Alt” select “Recovery Disk”, then “Disk Utility” and repair the HD volume by clicking “Repair Disk”. Then do a “Repair Permissions” again while in this recovery mode. Quit and reboot by selecting your drive as normal. Wait for Spotlight to finish a new index before opening any Apps.

Maybe do this, I didn’t need to:
6) Delete glyph fonts you don’t need. Google “Lion problem fonts”
7) Update Microsoft Office 2008, or delete it.

And hopefully you’ll be whizzing around in no time.
