Re: [avr-chat] AVRDude OSX High Sierra

[Bittrace14]

Managed to get it working. I used kext Wizard to install it 
(http://wizards.osxlatitude.com/kext/kw.zip). Kext Wizard installed it into 
/System/Library/Extensions and there it works fine. If I move the installed 
kext back into /Library/Extensions it no longer works, move it back to 
/System/Library/Extensions, it’s fine.
