Unfortunately, there is no official version of Power Automate Desktop available for macOS at this time. Microsoft currently only offers Power Automate Desktop for Windows.
You can Power automate cloud and can create a Flows.
If you need to use Power Automate Desktop on a Mac, one workaround is to run a Windows virtual machine.
(Note:- if you got your solution you can mark as solution and gives kudos)
