Macbook pro won’t update past OS X Yosemite 10.10.5
I am trying to update my laptop to OS X 10.11.4 (or later) so I can use iTunes to update my iPhone 8 with the most recent update. My Macbook Pro is from 2009.
What is the best way to update? I don't see anything in my App Store.
Thanks!
MacBook Pro 13″, OS X 10.10
