I have an 2008 mac pro 4.1 266 quad core. I finally decided to upgrade from 10.6 to 10.9 and put in an ssd. I installed the OS on the ssd and moved the applications over to the new drive. At first it seemed to work, but now the pin wheel interrupts even the most minor operations such as selecting folders on a different drive. This occurs even when I eject the previous system drive. Will reinstalling the applications be the answer? thanks in advance.
