CROSSGRADE FROM PERPETUAL TO ULTIMATE MEDIA COMPOSER

I upgraded (or downgraded) my operating system and reinstalled Media Composer but the license does not activate. How can I do?

The first advisable thing is to open a case with Avid through your account (refer to the internal ticket opening procedure) and ask for the license to be deactivated. Once you receive confirmation of deactivation, proceed with reactivation. In the meantime, to continue working, you can ask Avid for a temporary license if the deactivation times are too long or you can download the trial https://my.avid.com/get/media-composer-ultimate-trial

Does the annuity of the license start from the purchase or from the activation?

Starts from the activation date

Can I install my Media Composer license (annual subscription) on a notebook as well?
If so, does it have to have the same OS, or can I have, for example, Windows desktop and notebook OS?

You can install Media Composer on both Mac and PC. Here is the list of hardware features certified and supported by Avid: https://avid.secure.force.com/pkb/articles/en_US/compatibility/Media-Composer-System-Requirements
In detail, the link includes other links that refer to:
certified Windows computers, certified Mac workstations, workload performance recommendations, Mac and Win compatibility matrix.
The constraint remains that the same license can be activated on only one computer at a time: if it has been activated on pc A, before activating it on pc B, it must be deactivated on pc A (internet connection required).

I would like some advice on which Mac to buy for Media Composer
