EOS M Install - ML directory not found!

[fotomxr]

I'm not new to ML, running on 5D Mark II, but just got my first EOS M and cannot get it to install. I upgraded firmware to 2.0.2, unzipped a couple of versions and copied files to brand new ExtremePro 128 formatted in camera, twice, second time low-level format, always get error:

Magic Lantern Install.           Firmware 0
ML directory not found!         Bootdisk 0
Please copy all ML files.         RAM EXE -1
                                           Update -1
Please restart your camera.

I found one very disheartening message in the forum suggesting there is a but in Big Sur that prevents the camera from seeing the ML directory.  I'm running Big Sur 11.5.2 on a 2015 MacBook Pro.
I hope someone here can help!!!
