How upgrade from OS X 10.7.5 to newest version?
I have a MacBook (2008) unable to upgrade from os x 10.7.5 to at least 10.10 so I can update my Quicken for Mac. When I tried to upgrade, it said it could not be upgraded and when I clicked on "Learn more" tab, it didn't go anywhere. My memory usage has 16.59 remaining space. How do I do the update? What can be wrong w/ my computer.
