My Macbook pro is running slow. Should I do a clean install before installing Mountain Lion?
My Macbook Pro has been taking forever to start up, and open windows, plus I get a lot of the spinning wheel of slow death when I'm working in my design programs. I HATE messing with my systems, because something always seems to go wrong.
Also, I have an iMac too. Can I install it on both machines if it is downloaded instead of a disk? Is that allowed?
MacBook Pro, Mac OS X (10.6.8)
