On a brand new Retina MBP, if Safari is in full screen mode when I close it, it always reopens in a window. How do I get it to open in full screen mode (or whatever mode I left it in when I last quit)?
I rarely quit it, myself. Easier just to do a 4-finger swipe to the right.
But when I do go to the trouble of quitting, starting it up again will show the last page in whatever mode it was in before the quit. Unless I had private browsing selected, in which case it starts up small-screen.
I'm not in private browsing mode, just tried it again and it still won't open full screen.
I've just found the answer.
In System Preferences, go to 'General' and make sure where it says 'Close windows when quitting an application' is unchecked.
