I've seen number of websites with possible specs. But when does apple officially announce specs usually? Most sites say fall. So when does apple post which machines will run this and how much ram, etc I need? It's already very close to fall. Only few months away. And I have a Mid 2011 mini. 2.3 GHz Intel Core i5 8 GB 1333 MHz DDR3 Intel HD Graphics 3000 512 MB Mac OS X Lion 10.7.5 (11G63) It came 2gb of ram And I tossed that out and added 8gb. So is this good enough for maps, all the eye-candy, heavy apps etc? Or do I need better and this is too slow? I assume it has to be good as no new mac mini cam out in 2012 or 2013 so far. But it could still lag with integrated graphics and such for all the new features coming out. So just curious. And what kind of machines is everybody else running the previews on? Just curious.
