cannot find it on NI
What version of macOS is your new Mac running? Is it a model with one of Apples own M chips?
In that case: Traktor Pro 2 won‘t work on your new Mac. With an installer you may can install it (in fact I got it installed on my Mac Studio with M1 Ultra) but activation with Native Access won‘t work. Therefore you will be stuck in demo mode.
You‘ll need at least Traktor Pro 3 or 4. Both are paid upgrades, only the upgrade to TP4 is still sold.
If you are talking of an older Mac with older versions of macOS you‘ll find legacy installers in this link: https://support.native-instruments.com/hc/en-us/articles/210294645-Traktor-Pro-Legacy-Installers-for-Older-Operating-Systems
