I need help to reinstall Traktor pro 3 on my old MacBook. Is this even possible?
As long as you still have a licence for Traktor Pro 3 and your MacBook is compatible with Traktor Pro 3, it should work.
The last version Traktor Pro 3.11.1 can be installed with Native Access but requires that you use macOS 11 or newer.
You can get older versions via that link if necessary:

You still need a matching version of Native Access for your OS to activate Traktor.

okay guys, I got it installed and playing but now I can't seem to get it out of demo mode. Don't get frustrated with me it's been a while since I played with my system so here's the new question: how do I register this?
Did you log in with the account that has TP3 registered?
