Finder menu "Go To…" > "Library" or press shift+cmd+L.
Thanks, after following your directions, I learned that i had indeed already found that library folder, but am not finding the files that macdude mentioned (which made me question if I was using the correct technique).
Games are not bought through GeforceNow, but there are only specific games that are fully supported. I.E. I can sign into steam and run any game (well try to run) but it will have to reinstall on the cloud computer every session (and if they don't have steam cloud your games aren't saved) . Supported games are instantly available from any session with save support.
Hey, thanks for he swift reply, man! There are some specific games that I'm really interested in: Destiny 2, Overwatch, Doom, Wolfenstein (the new ones), DEMD, the Metro Redux games, Rise of the Tomb Raider, Dying Light, Borderlands 2 and Borderlands TPS.
