I didn't install my software update for years, and now my Mac cannot find any update whatsoever.
Hi,
I use MacBook AIR (13-INCH, 2017) with macOS High Sierra, Version 10.13.6.
I want to update it to the newest possible macOS, but unfortunately, my computer doesn't find any updates.
I have received notifications to update my computer for years but have not installed them, and now this option disappeared.
