I'm sure this has been asked but I've looked through many of the pages on the news stories, and I've also looked on the OSX forums from today and didn't find anything, so . . . I have three macs. An iMac for home, a personal MBP I use at work, and a mac mini connected to the TV. If I download an app from the Mac App store, will that work on all three of my computers? It appears to be setup similarly to the iTunes store, that each purchase is connected to your itunes account. If this is that case, then wouldn't one purchase work on all machines? When I buy a movie from itunes I can play it on any computer (up to 5), along with any ipod, iphone, ipad. Thank you! Never mind, I found my answer on Macworld. http://www.macworld.com/article/156962/2011/01/mac_app_store_faq.html?lsrc=top_1 The answer is yes, multiple computers are fine, as long as they all are signed in with the same itunes password. Hmm, Aperture is looking awfully tempting . . .
