Mac OS X 10.7 Lion DOES Ship With X11
And I’ve got the eyes to prove it. There seems to be some concern online that Lion ‘ships’ (can we even say that any more?) without X11. Well, one of the first things I’ve checked out on my retail copy of Lion is X11, which is present as ever.
Open a Terminal window, type ‘xeyes’ at the prompt and you’ll see X11 staring right back at you.
This installed by default on my MacBook Pro, but if you find it missing from your installation you can install it from the ‘Packages’ folder on the Lion install USB key/DMG.
