Apple macOS 12 Monterey supports the second Mac as an external display: both wireless and wired

macOS 12 Monterey supports sending content to a second Mac via AirPlay. Users can also use this feature to perform screen mirroring, turning a backup machine into an external display.

In addition to using AirPlay wirelessly, macOS 12 Monterey also allows users to connect two MacOS devices with a USB cable , which greatly reduces latency and eliminates the need for wireless networks.

Even when there is a Wi-Fi network, using USB may be more popular because it makes the connection smoother and more responsive. However, since AirPlay automatically compresses the content before transferring it to the second device, it is unlikely to completely eliminate the delay.

This feature allows iMac models from 2009 to 2014 to be used as the second display of another Mac. AirPlay to Mac will be applicable to the following machines:

MacBook Pro 2018 or later

MacBook Air 2018 or later

IMac 2019 or later

IMac Pro 2019 or later

Mac Pro in 2019 or later

Mac mini 2020 or later

Naijatechnews has learned that the official version of macOS Monterey will be launched this fall and will provide free upgrades for all compatible devices.
