How to program the ATTiny85 on MacOS Sierra

Check MacOS version

$ sw_vers 
ProductName:	Mac OS X
ProductVersion:	10.11.6
BuildVersion:	15G1611

Check usb connected

No driver should be necessary. Beware that it does not show up as a serial port

system_profiler SPUSBDataType | grep USBtinySPI
# USBtinySPI:
#   Product ID: 0x0c9f
#    Vendor ID: 0x1781
#    Version: 1.04
#    Serial Number: 512
#    Speed: Up to 1.5 Mb/sec
#    Location ID: 0x14243000 / 17
#    Current Available (mA): 1000
#    Current Required (mA): 200
#    Extra Operating Current (mA): 0

Test with different cables and USB hubs. The ports on the computer might not work bco USB3.

Setup and compile using Arduino

• In Arduino go 'Preferences'->'Additional Boards Manager URLs' and add https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-manager/package_damellis_attiny_index.json.
• Go 'Tools'->'Boards' and choose 'ATtiny 25/45/85'
• Go 'Tools'->'Programmer' choose 'USBtinyISP'
• Go 'Sketch'->'Export compiled binary'

Upload

Download and compile micronucleus using make CONFIG=t85_default.

Finally we upload to device:

micronucleus --run Blink.hex/Blink.hex.ino.tiny8.hex

http://littlewire.github.io/

I get the same:

system_profiler SPUSBDataType | grep USBtinySPI

2020-04-04 00:05:16.544 system_profiler[11062:5013857]  SPUSBDevice: IOCreatePlugInInterfaceForService failed 0xe00002be

ProductName: Mac OS X
ProductVersion: 10.14.6
BuildVersion: 18G3020

as a beginner with the ATtinies I have absolute no clue what program I would have to use to compile „micronucleus“ :-(
Will Terminal do that for me?

Sorry, my notes are not meant as a beginners tutorial. Yes, you would download the source code and follow the process laid out by micronucleus in order to get that compiled. Probably using the Terminal.

Thank you for this fast response.

I documented my adventure and eventual success with some step by step instructions. Here it is in case it is helpful: https://www.jasonacox.com/wordpress/archives/518

Hi Jason, very well written and documented, thank you for this link. Too bad, I cannot find this specific programmer on Amazon or eBay. Any suggestions for a working substitute and what version of the Arduino IDE works best? Kind regards, Michael

I used this SparkFun AVR Programmer (Amazon Link) which works well with the Arduino IDE.

Just use a USB extension cable on a MacBook! I tried all but it will only work if it's not directly inserted in the USB-ports, strange but true.
