Cannot update 10.7.5 to High Sierra
I'm trying to update my MacBook Air (2011) OS X 10.7.5 to High Sierra. When I try it says: This update requires macOS version 10.8 or later. I attempted to update software and there are not any updates. Now what? Thanks.
MacBook Air (13-inch Mid 2011), Mac OS X (10.7.5)
