Hi @Jefro113, Thanks for posting and being a part of the Community.
If you're trying to listen on the Pandora app from your Mac, all you need to do is log in with the email address you registered to Pandora with. There is no activation code needed to listen from your Mac.
Please note that Pandora accounts follow the email address, not the device. So you can sign into the same Pandora account on any computer or supported device, as long as you use the same email address and Pandora password. This applies to both free and upgraded Pandora accounts.
If you need to create a Pandora account, please go to pandora.com.
Click Sign Up in the upper right corner.
Enter the required registration information (be sure to enter your birth year and not your entire birth date).
Review the Terms of Use and Privacy Policy.
Click Sign Up.
Let me know if you have any trouble. Thanks for listening!
