Is Desktop Premier 2019 compatible with a Mac Computer
Yes, but. The but being buy windows for mac and install windows in boot camp on your mac , then you can purchase and install desktop premier.
If you don't need premier then you can just buy pro for mac
Below are the requirements I found for the Mac version (posted 12/10/18). You can also run the PC version if you also have Windows installed on your Mac. Some people find it more stable and more users available for support.
Minimum system requirements
As far as I can tell, however, there is no Premier version directly compatible with mac - there may be compelling reasons to use Premier and not Pro
