Can I move my license from windows to mac?
If so how do I go about it
The NI licenses are not tied to the operating system, simply install Native Access on the MAC and log in, then the licenses are taken from the Portal and it can be installed.
You may install some of the NI SW on two computers and some on three. Under the condition you use just one computer at a time.
