Digispark Attiny85 will not compile

Hi all,
I received some digispark attiny85 microcontrollers today, but am not able to compile code for them. I have installed the boards in the boards manager. When I try to compile, I get this error:

fork/exec /Users/xxxxxxx/Library/Arduino15/packages/arduino/tools/avr-gcc/4.8.1-arduino5/bin/avr-g++: bad CPU type in executable
Error compiling for board Digispark (Default - 16.5mhz).

I am running this on a Macbook pro with MacOS Catalina 10.15.4. Arduino IDE is version 1.8.13
Any help with this would be appreciated. Thank you!

Update: I can now compile however the code will not upload to the board. I have plugged it in when is says but it does not seem to recognise the board. (It does supply it with power)

I suppose you are no longer following this question, but just in case someone else lands here.

  • Do you have the board that plugs directly into the USB port of your Mac?
  • If you are using one with the mini-USB port connected with a cable, make sure to have a cable that uses all the pins. Most cheap cables only provide power.
  • Do you see your device in the Tools | Port menu of the Arduino IDE? It should show as /dev/cu., for example: /dev/cu.SLAB_USBtoUART. It could be an issue with the device driver and macOS version

HTH
