FairerPlatform’s Ron Carlson notes that whether you have an older model thats getting slow or a brand new Christmas Mac, if you don’t use the Dashboard, there’s no reason to let it live. “Kill it, now,” Carlson advises, since disabling Dashboard will reduce RAM, battery and system resource usage, and it’s surprisingly easy to do. (Works for OS X 10.8 Lion too)
Carlson also suggests a Dashboard disable method for users running OS X Snow Leopard.
I haven’t tried this yet, but it’s on my shortlist. I never use the Dashboard, so why keep it up and running using up system resources? How about you?
