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.
This was the only thing I used to accomplish what I set out to do. Thank you for your help. No other way worked but this way.
