Astropad has updated its Luna Display app to allow users to use one Mac as a display for a host not just over wireless networking, but also over a wired Ethernet or Thunderbolt connection. Apple stopped supporting Target Display Mode back in 2014 with the release of macOS Mojave. But, as Astropad announced on Wednesday, Luna Display now offers a wired, third-party workaround. "Previously, Mac-to-Mac Mode only worked over Luna's wireless connection. With today's update, Mac-to-Mac Mode will also support Ethernet and Thunderbolt connection between Macs, with a seamless set-up process," Astropad wrote. The feature will allow users to use a Mac as a secondary display with full trackpad and keyboard support across both devices. As the company notes, users can leverage multiple combinations — including a MacBook Pro and a Mac mini or two MacBooks.
