I haven't been able to open the Tiny TV Converter app to load content onto my new Tiny TV 2.
I first tried on my work Mac and got the error that you warned of - opened it again via Finder, clicked "Open" in the warning box, and then nothing happened. Further tries in opening the app don't do anything (either it's opening and immediately closing, or it's never opening.)
I was wondering if it was because I was using a work computer without the admin password, so I tried again on my MacBook Pro at home. The exact same experience.
My only other computer is a Chromebook so I can't use that.
Any advice? Thanks.
