Getting ATMEL ICE to work on OS X (Catalina)

⚠️ This solution doesn't work on latest versions of macOS (Big Sur, Ventura). Check comments for more up-to-date solutions. ⚠️

The following sequence of commands will download the included Info.plist file and install it into the system kext directory as a dummy kext.

sudo mkdir -p /System/Library/Extensions/AtmelICE.kext/Contents
curl https://gist.githubusercontent.com/carlossless/31dc73963d589f18a20b582e787b6206/raw/Info.plist > /System/Library/Extensions/AtmelICE.kext/Contents/Info.plist
sudo chown -R root:wheel /System/Library/Extensions/AtmelICE.kext`
sudo chmod -R 755 /System/Library/Extensions/AtmelICE.kext
sudo kextcache -system-caches

Product IDs

Take note of the product ids of your actual device. I've seen different ones being used. An easy way to check that is to use lsusb. Then convert the product id from hex (base 16) to dec (base 10) and change the idProduct value in the plist.

AVRDUDE ISP speed

ISP flashing might be very slow when using AVRDUDE, to make it faster use the -B 1 flag.

Note: this requires a higher clock speed of the device too.

I came up with a solution: http://hinterm-ziel.de/index.php/2021/07/13/avrdebug-and-atmel-ice-under-macos/

I basically set up a brew formula that you can use to install avrdude from the most recent codebase.

Under Big Sur:
"sudo mkdir -p /System/Library/Extensions/AtmelICE.kext/Contents
Password:
mkdir: /System/Library/Extensions/AtmelICE.kext/Contents: Read-only file system"

Hi jdar,

Under Big Sur:
"sudo mkdir -p /System/Library/Extensions/AtmelICE.kext/Contents
Password:
mkdir: /System/Library/Extensions/AtmelICE.kext/Contents: Read-only file system"

have a look at my solution: http://hinterm-ziel.de/index.php/2021/07/13/avrdebug-and-atmel-ice-under-macos/
