Trim your Extensions & Controls Panels to help performance and prevent possible extension conflicts; if you are a Newbie to OS 9, when in doubt, don't turn off an extension unless you are sure you don't need it, the amount of RAM saved is not worth the headache you are going to have if you inadvertently turned off something you need and don't realize it…if you want to experiment, you can use this guide first as a baseline and then pick “Duplicate Set” and try variations of your initial modified setup, that way, you can easily switch back if you make a mistake

From the Apple Menu, choose the “Control Panels” pop-up, and click EXTENSIONS MANAGER.. Click “Duplicate Set” at the bottom right corner of the Extensions Manager window. Name the duplicate set when prompted… something like “Recording Studio Mac” or your name as an Artist or Production Company

Sort First… it will make the below list much easier !

Click on the word “Package” at the top of the Package column to immediate sort the Control Panels and Extensions, this will immediately give you a bird's eye view of which packages belong together

After an Initial Mac OS 9 Install navigate to the Extensions folder in the System Folder, select all the files (hold down Command/Apple and press 'A'), and label them with a color. This way, any third-party extensions added subsequently are easy to spot since they will appear with a different color to the original set and these colours will be visible in Extensions Manager!. Remember to load your mac up to 1 GB of RAM and allocate to the Host DAW Application as much as possible (Get info, Command-I on the Application, switch to “Memory” and set both memory values to 400,000 or more for your main Application if it hosts many plugins).
