Ok I was reading the February edition of Macworld and it had a whole prevent mac disasters section. There was a few things I had not grasped so well, and was hoping some of my fellow mac rumors asociates would be glad to help. They had listend 7 steps. ? means I would like some help. 1. Verify Prefrences? - plutil in terminal or Jonathan Nathan's Free program Preferential Treatment which I have used and didnt really notice any difference.(Not so sure how the app works) 2. Repair Permissions 3. Delete Cache?- Says its in System:Library:Caches Folder. Do I just go in there and erase the whole folder? 4. Delete Log Files? - Says OSX has maintenance scripts to take care of this, not sure where though. (/Library/Logs)? 5. PreBind - Any 10.3 + OS's automatically optimize or PreBind for you. (Terminal command - sudo update_prebinding -root /) This should be correct as is. 6. Automate Your Maintenance - Unix scripts that rid and clean up cloging files. Run times= daily 3:15am, weekly 4:30am Saturdays and the Monthly at 5:30am on the first day of the month. 7. Smart Stat Indicators - Disk Utility click the top HD in the left hand column. Then on the bottom right you should see Smart status and it should say verified. IF no smart status your computer does not have the technology. If you have smart status but no verification then you should backup and reinstall the os.
