APP can’t be installed on “Macintosh HD” because OS X version 10.11 or later is required.

How do I update to 10.11 or later. It doesn't even come up as a software update needed? Currently have OS X 10.9.5

Open the App Store and click on Updates. It should show any available updates, including OS versions.

Mac OS X 10.9 was released in 2013, and 10.11 was released in 2015. Have you not run any OS updates since then?
