Same question? Any update?
From the Arduino IDE I see the board, but not the programmer, though micronucleus is there.
Installed libusb-1.0.19 and when trying to upload I get in the IDE
Running Digispark Uploader...
Plug in device now... (will timeout in 60 seconds)
dyld: Library not loaded: /usr/local/lib/libusb-0.1.4.dylib
Referenced from: /Users/knud/Documents/Arduino/hardware/digistump/avr/tools/micronucleus
Reason: image not found
If I link the libusb-1.0.0.dylib to libusb-0.1.4.dylib, I get
Running Digispark Uploader...
Plug in device now... (will timeout in 60 seconds)
dyld: Library not loaded: /usr/local/lib/libusb-0.1.4.dylib
Referenced from: /Users/knud/Documents/Arduino/hardware/digistump/avr/tools/micronucleus
Reason: Incompatible library version: micronucleus requires version 9.0.0 or later, but libusb-0.1.4.dylib provides version 2.0.0
which really seems confusing.
I suppose I'll move to linux and see if that can work, but I'd much prefer to keep all my arduino dev where it is, on my Mac.
