The AtmelICE, unfortunately, presents itself to the host as a HID device. That means that unless steps are taken, it’s not possible to use avrdude on MacOS X to talk to it through libusb because the HID stack claims the device.
The workaround up to now has been a dummy kext, but High Sierra has closed off all of the avenues to use unsigned kexts - even those that don’t actually have any code. So I ponied up for a year of the Apple dev program and asked Apple for the ability to sign kexts, which they graciously have allowed. And thus, voila, I’ve made a signed dummy kext for the AtmelICE.
