Apparently this applies to the Helicon Remote via Android. Not just MacOS.

I got it to pair exactly once, no more. No error messages like with the desktop version, or at least nothing bubbling up to me.

So I've gotten EOS Utility 3 to work with the Camera, and Helicon Remote via USB - But I cannot seem to get the utility to finish connecting.

I even see the Camera show up under network settings, but we can never finish a handshake, the camera eventually errors out with a Error 11.

I'd open a bug ...
