Which Devices Run macOS Monterey?

macOS Monterey, previewed Monday at WWDC 2021, runs on devices from late 2013 and older. Of course, this depends on what kind of Mac you are using.
Devices That Run macOS Monterey
macOS Monterey runs on:

iMac – Late 2015 and later
Mac Pro – Late 2013 and later
iMac Pro – 2017 and later
Mac mini – Late 2014 and later
MacBook Air – Early 2015 and later

However, it’s worth nothing that not all the new features work on older devices. In particular, some require a Mac with an M1 chip.
