How to slim down that old, small hard drive so your Mac runs faster
ANOTHER WAY TO make your old Mac run faster is to declutter its hard drive —getting rid of old, unwanted apps, backing up and archiving media and files you’re not likely to need any time soon, and moving currently used media to external drives. Moving large media files such as your music, movie and photos libraries does much to free up valuable hard drive space.
Back up, back up, back up
You can never have too many backups. Before migrating your media libraries from your old Mac’s hard drive to an external drive, it’s a good idea to back them up. There are numerous ways to do this. As discussed before, you can clone your hard drive in its entirety. You can simply drag your media onto another external drive or even aDVD burner to protect against loss while migrating. And don’t forget Time Machine. As long as your older Mac runs OS X 10.5 Leopard or later, that’s an option.
