Cant update Lion to Sierra
I have a Macbook Pro OS X Lion 10.7.5. In the app store I cant download Sierra. Ive backed up my computer and Ive also restarted in recovery mode and done a disk repair. The disk is perfect. Still cant download. Do I need to go to an older version first? If my computer runs fine now, do I really need to install any other operating system?
Anything you guys suggest would be much appreciated.
MacBook Pro, Mac OS X (10.7.5)
