I have a macbook and an iMac both running the newest OSX update. Both machines are running a 2.0ghz core 2 duo processor and 1gb of memory. I am constantly getting the beachball when working with applications. People have told me that I need to up my memory to 2gb but I really think that OSX should run fine with 1gb of memory. I have run Onyx to delete all the clutter from both machines but I am still getting the beachball. Any suggestions?
