Apple Mac can link another Mac as an external monitor on the new system

One of the main new features of macOS Monterey is the ability to play AirPlay content from other Apple devices (such as iPhone, iPad or another Mac) to Mac.

According to the function page of macOS Monterey, the working method of AirPlay to Mac is wireless or wired using a USB cable.

Apple pointed out that wired connections are useful when Wi-Fi connections are not available.

AirPlay to Mac also allows users to extend or mirror the display of Apple devices to the Mac, which makes it possible for a supported Mac to use another Mac as an external display.

It is worth noting that these new AirPlay functions cannot completely replace the target display mode, because Airplay not only compresses the video transmission, but also has some delays.


Starting with macOS Monterey, a supported Mac can also be used as an AirPlay 2 speaker source, allowing users to wirelessly transfer music or podcasts from Apple devices to the Mac.

Or use the computer as an auxiliary speaker for multi-room audio.

AirPlay to Mac is suitable for 2018 or later MacBook Pro or MacBook Air, 2019 or later iMac or Mac Pro, iMac Pro and 2020 Mac mini.

macOS Monterey can now provide developers with a beta version, and the public beta will be launched in July. The software update may be publicly released for all compatible Macs at some point between the end of September and the beginning of November.
