Update Mac OS X 10.7.5
How do I go about updating my current operating system on a 2011 macbook pro? Currently I have Mac OS X 10.7.5
When searching for latest updates my computer would not allow the latest upgrade to download as Im assuming it was to outdated. I have backed up my computer already and am hoping to find a free upgrade to a more current operating system.
Any help would be greatly appreciated.
MacBook Pro 13", macOS 10.14
