Found an issue.

Scroll Lock doesn't work on macOS server side to lock cursor to device.

From Windows to macOS this works out fine.

#Synergy #Synergy3

Got the #Synergy3-upgrade notification (well, subscription/SaaS now), but received five years of upgrades for having a Synergy 1 and "2 Pro"-license.

It works, and doesn't suck (for now).
