Luna Display turns your Mac into a secondary screen for your other Mac

Luna Display, the solution that lets you use an iPad as a secondary screen for your Mac, now works from Mac to Mac. Announcement of the new functionality in a blog post, Luna Display says the feature works between any combination of iMacs, Mac mini & # 39; s and MacBooks running on macOS 10.8 Mountain Lion or higher.

In a chatter, Luna Display CEO Matt Ronge said the functionality was a direct answer to is "sherlocked" by Apple & # 39; s new Sidecar function, which builds much of the functionality of Luna Display native to macOS Catalina. With Apple's first-party solution, you can only use iPad tablets as a second screen.

The new functionality should help you find an application for every old Mac lying around that you might have been tempted to sell or recycle. About Bold fireball John Gruber notes that the feature will be especially useful for anyone who has an older 5K iMac, who now has the option to link that computer's excellent screen with more modern hardware.

Luna Display is not the only company that is challenged by Sidecar from Catalina. Duet offered a similar Mac to iPad screen sharing app (without the dongle), and responded by strengthening support for non-Apple hardware. It already worked with Windows PC & # 39; s and earlier this month it added support for Android devices.

To use Luna Display's new Mac-to-Mac functionality, you (of course) need two Macs and one of them Luna’s $ 69.99 USB-C or Mini DisplayPort dongles. Your host computer must be running macOS 10.11 or higher, while the secondary Mac must be running macOS 10.8 or higher.
