Where were the links to buy a license should I want to buy this last version of NX 12 on mac, or continuing versions on windows? I am interested in the solid modeling/CAE modules.
If your NX maintenance is up-to-date you can currently download NX 10, NX 11 or NX 12 for Windows or MacOS.
Note that there are no maintenance release updates for the Mac version of NX 12 and that support for NX 12.0.0 (base release) ended May 17, 2018.
