Switch to from Compatibility to CORE in the head tap setting (second from the left).
Then you see which OpenGL features above 2.1 are available. Also the Summary info changes from 2.x to 4.x Driver - if your card can handle it.
So all OK!
my gpu alkso would NOT show 2.1++ features if i use Compatibility vs CORE - thats normal and doesnt matter OS X version (10.x+) .
