A witch says,
The developer dropped LimeLM/TurboActivate DRM and went to their own system. They initialy used iLok and this is the second change for them. It is now true keygend with full ProTools AAX compatibility.
Their protection uses values from BIOS to generate challenge code (JUCE). As long as you are using same hardware, generated licnese should work on macOS too.
Now they finally lost reasons to protect by spending money and time - the true keygen works for the updates too ;)
