MacOS Big Sur "No devices found"

Hey, I just got the Drop CTRL and tried loading the firmware on a MacOS Big Sur, but I get this message:

❯ ./mdloader_mac -l
Massdrop Loader 1.05

Seems like an issue with the keyboard itself (changed the chip?), as it also happens on Ubuntu (Focal)

For anyone experiencing this, Karabiner for Mac is a pretty solid alternative.

keyboard has to be in programming mode to read it

try

sleep 5; ./mdloader_mac -l

hit ENTER and then press + hold Fn + b for 3s and then release. All LEDs will go off, and after 5s your kbd should be printed to the terminal.

$ sleep 5; ./mdloader_mac -l

WORKED FOR ME. THANKS, @luckman212.
Just write step by step here:

1. sleep 5; ./mdloader_mac -l
2. Hold Fn + b for three seconds.
3. The Drop Keyboard led will be turned off
4. Now, You cannot use the Drop keyboard, please use the internal keyboard instead
5. Use the internal keyboard to type ./mdloader_mac -l
6. The keyboard list will be shown here.
7. Use the internal keyboard to load a new configuration if you want.
