Okay, I can confirm…it works without Rosetta! I use Logic Pro as my DAW on a brand new MacBook Air M1, and when you first launch LP, a window will pop up with two buttons; one will ask you to ignore and continue, the other will say there is a problem…click on that button. You get a window that shows all of the plugins running in LP on the left side (Focusrite, Line6, etc…), basically the manufacturer of the plugins. Click on Line6 and on the right you will see the line entry for Helix Native. Scroll a bit to the right and that line item will have a “use” checkbox. Click it to put a check in the box, and hit “Done”. That’s it, it will work. When you create a track, say for guitar, open the mixer and click on “amp” for that track. Line6 appears as an option, that’s Helix Native. I also plugged in my Helix floor unit, opened Helix Edit, and drug all of my IRs and presets into Helix Native so I have those as options as well. Works like a champ!!
