well, seems easy - iLok is good on Mac and erratic on Windows, syncrosoft good on Windows and erratic on Mac. for me as well - zero problems with iLok ( but also with Yellowtools Wibu or Logic Key) - lots and never ending headaches with syncrosoft.
i mean, one buys samples for thousands of euros ( high priced product -and high quality product) and then needs to get a piece of plastic that is poorly manufactured, feels cheap and fragile ( the drivers on mac are exactly that as well) to copy protect it. if you run into problems they tell you to connect the dongle to a USB-port on the computer and not to a hub - how realistic is that as a solution? maybe they should buy Apple and other manufactures first so they can command that computers have at least 16 USB-ports for all the dongles, USB interfaces, keyboards, mices, etc.
Alone this support answer it outrages - to me it is an expression that they are not that interested in problems their users have with this dongle.
