Dos and Doníts
1. Don't let your system go to sleep or put your drives to sleep. System Preferences -> Energy Saver. You can however let your display sleep.
2. Don't defrag your drive.
3. Do make sure you have at least 1GB of free space on your startup partition
4. Don't have Classic (OS9 emulation) running when you use Logic.
5. Don't use Norton Utilities. If you have Norton Utilities installed, Uninstall it.
[Search for symOSXKernelUtilities.kext and delete it] then uninstall anything else related to Norton Utilities.
(note: symOSXKernelUtilities.kext is owned by root. you will need to use the terminal or cocktail to delete this file.)
6. Do Not let resource-hogging startup/login items that you don't know about run in the background.
(scanner, printer, and other utilities that load on startup and continuously run in the background eating up system resources)
7. Do create a fresh Autoload when you update Logic
8. Do Repair Permissions after installation of any new software.
Its also a good practice to repair permissions on a regular basis.
