While there are multiple options for using an iPad as a Mac’s second screen, Luna Display is adding a twist: the option to let one Mac take over another Mac’s screen.

This, for example, lets an iMac easily use a MacBook’s display.

Luna Display Mac-to-Mac mode rescues older computers

Or this new feature lets someone with a new MacBook use their old laptop to expand their screen space. The primary computer has to be running macOS 10.11 El Capitan or later, but the secondary one can be running an operating system as far back as macOS 10.8 Mountain Lion, which debuted in 2012.

“Finally you can give purpose to your old Macs lying around. No need to have any idle devices!” notes Luna Display’s developers.

But Mac-to-Mac mode doesn’t have to be only for obsolete computers. Someone who carries a MacBook with them everywhere but has a more powerful Mac in their office can make use of the notebook’s display rather than just leaving it in a bag.

The mouse, trackpad and keyboard connected to either computer can be used.

This new feature for Luna Display is in addition to this accessory’s primary function: turning an iPad tablet into a second screen for Macs of all kinds.

The hardware necessary for either option is $69.99. The software is free. An update to the macOS app to add Mac-to-Mac mode will be available tomorrow, October 17 at 10am PST.
