I am using a 1st gen intel IMac running Lion 10.7.5. I am on a jailbroken 4S running IOS5.1.1. I understand that I wont be able to do Airplay mirroring because 1st gen intels dont run it correct? Do I have to update my IOS (losing my JB) to 6 to do the airplay from my phone? Do I also have to update to Mountain Lion in order to access IPhoto/photostream or am I unable to do that because of the first gen thing anyway? I know a lot of questions but I am just trying to make a well informed decision. Thanks folks!
