I did not know that one can STILL get Snow Leopard.....
I recent check with Apple to IF I can STILL get Mountain Lion (ML) for a late 2010 MacBook Air. WOW, to my surprise 😮, the link that was sent to me to purchase ML, also had an option for Snow Leopard. I thought it was extinct. Who knew! Ask and you shall recieve.
MacBook Air, Mac OS X (10.6.8)
