No.
The perpetually licensed Suites (which includes Production Premium) are platform specific: Windows only or Mac only.
The Creative Cloud is multi-platform. The same license works on Windows and/or Mac.

If you buy a new full Mac version (most expensive route) then no. You will then have a Windows only license and a Mac only license.
If you choose to "crossgrade" (swap the Windows only license for a Mac only license) then your Windows version will no longer be licensed so you'd uninstall that.

Yes if you want to switch your Windows only CS6 to a Mac only CS6 - known as a "crossgrade".
