Please remove activation from old Mac

[MichaelS28]

I no longer have the Mac I activated Parallels in and I cannot activate one I just downloaded because it says it is already being used. Can you please deactivate the other Mac?

Thanks

Hello MichaelS28 ,
We have made changes to the activation key. Please follow the instructions below:
1. Quit Parallels Desktop, then try to activate after launching it again.
2. If you are still unable to activate, Open Terminal on the Mac and execute this command: prlsrvctl activate-license-online
