Pretty cool but there are bugs

I mean it’s cool and it works all the features are good but the recording part gets buggy every time I try to rename a song I’ve recorded it just deletes and I can’t write anything

Why is this not Macbook Compatible

Everything is really cool but as a laptop user it’s easier to watch lessons, connect to my DAW Logic Pro and use my Allegro 4 all in one device. I don’t want to use my iPhone it defeats the purpose lol
