Windows to Mac

Hello, I just recently purchased a Mac book pro. I already have a license key for my windows computer, is there anyway I can transfer that license key to my Mac instead of buying a new one. Thank you

Do you have a V5 or V6 license for Windows ? In the case of V5, no crossover is possible, but with a V6 license it is possible in some cases.

I have v6 so what should I do

If you have a full V6 license (not an upgrade over a previous version), you can go here and with your V6 key, get a V5 for Mac “legacy” license for the current version of Rhino for Mac. Your current V6 license will also be valid for the future V6 for Mac when it comes out.

Unfortunately the above does not apply to upgrade versions of V6, only full versions.
