Question: How do I update my IOS from 10.9 to 10.12 or higher?
I am trying to update the IOS on my MacPro from 10.9 to 10.12 (or higher) so that I can download Pages. I searched the Apple support site but did not see anything applicable to this. I apparently cannot update to High Sierra.
I appreciate any help.
MacBook Pro, OS X Mavericks (10.9.5)
