Hi guys, I'm new to Mac. Been using iPhones for years though. Quick question (though I might have many more)!..... If I have a few users on my iMac.....and I downloaded Spotify, for example (from the web, not the App Store), on one of them.....can I use this program on another user's account on the computer without having to download it again? If we keep downloading some of the same program, it is just simply using more memory to access the same thing. Thanks in advance!
