Parallels

Parallels is a subsidiary of that produces virtualization software to allow additional operating systems to be run simultaneously on the same hardware.

Parallels Desktop for Mac
Parallels Desktop can allow Macs to simultaneously run Windows 7, 8.1, and/or 10 under macOS. The Apple M1 processor (which no longer supports Boot Camp) can user Parallels to run Windows ARM apps natively and Intel apps in emulation. It is recommended to have generous amounts of memory installed to accommodate each operating system being virtualized by Parallels software. Parallels Desktop 17 allows Windows 11 to be installed, but it is not officially supported by Microsoft.

The Business and Pro Editions of Parallels Desktop can also virtualize older versions of Mac OS X to run as a session within modern versions of macOS. Virtualization of Mac OS X 10.5 (Leopard) Server through macOS 10.13 (High Sierra) is supported.
