I thought it would be as easy as plugging the Switch Lite or SD card into the Mac and moving the NSP files over into a folder. I have no idea what I’m doing obviously.
Edit: I attempted to transfer files over from my Mac using Android File Transfer and DB Installer. It looked very promising but AFT closes and reopens over and over again.
Thank you. Do you have to do something on the Switch once in Tinfoil?
You should have the games viewable on tinfoil on the computer, then on the switch use the the file browser on tinfoil to see them and select the ones you want to transfer and install. I think the desktop tinfoil app is called NUT or something?
