There are many ways to improve your Mac’s performance including getting updates for software or hardware device drivers, disabling system-intensive screen savers and themes, choosing the appropriate display for your Mac, and obtaining and using a third-party performance enhancer.
These can make a noticeable difference. However, if you have an old Mac and have run out of options, check out these performance tweaks:
· Disable menu fadeouts by downloading and installing FruitMenu. Menus will snap in instead of fade in, saving a millisecond or two.
· Disable file sharing if you don’t need it (System Preferences>Sharing).
· Deactivate Remember Recently Used Items (System Preferences>Appearance).
· Disable Font Smoothing (System Preferences>Appearance).
· View pictures in iPhoto by roll.
· Turn off extensions in Classic that you don’t need.
· Disable fonts you don’t use.
· Change the spring-loaded folders and windows delay to Short (Finder>Preferences>General).
· Disable Calculate All Sizes in the Finder windows (View>As List, then View>Show View Options).
· Avoid using iTunes to play music while also trying to perform a system-intensive task such as editing a large photograph or editing a movie. There just might not be enough power to do both effectively.
· Install more RAM.
· Continue degunking.
There are lots of tweaks that, although seemingly insignificant when performed separately, really add up when combined with others.
