Went iMac two years ago, love it, never going back to Windows. I'm getting ready to purchase a new 27" iMac after the refresh, and will be giving my 21.5" iMac to my wife. My questions: - When I set-up my new Mac with my AppleID, will I be able to install all purchases I've made on the appstore onto the new computer? - Will I then have to uninstall the apps from my old computer, or is the appstore a "buy once/install many" type thing. Probably a newbie question, but I've never been in this situation before. Thanks.
