This quick guide will help you get familiarize with Luna Display and its features.
Starting Luna Display
After successfully connecting the Mac and iPad apps, you’ll notice the iPad’s screen is another Mac desktop screen. Just like connecting another monitor to your Mac, depending how your Display settings are you may see another desktop background or files shift over.
This can always be adjusted through MacOS System Preferences. If you're not seeing a menu bar on the top of the iPad screen, most likely "Displays have Separate Spaces" is disabled in Mission Control settings. For more information on this, please check our FAQs.
Screen settings & Arrangement
Also after successful connection, a menu with Luna Display's General Settings will appear.
Here you can set Luna Display’s arrangement to the left or right side of your Mac Desktop. Or select Custom, to quick access Display settings and resolution from System Preferences in MacOS.
Retina Display Enable
Below the screen arrangement is also buttons for non-retina or enabling retina use.
When first running Luna Display, this feature is turned off. To enabled retina, the Luna Display Retina Extension will need to be installed.
There will be a window to prompt this — In System Preferences, go to Security & Privacy, and under the General tab make sure “Allow apps downloaded from” is accepted for Astro HQ, LLC by clicking “Allow” button. Afterward the extension will immediately install.
*Please note — If your Mac does not have retina supported, use of retina cannot be enabled.
If the iPad is not retina compatible, this will not be possible either.
When Retina is enabled, the screen resolution on the iPad side sets to Luna Display's HiDPI option by default. This setting accommodates for both retina and screen size of the iPad. If a different size is preferred, this can always be changed in System Preferences under Display.
Showing the Sidebar
Place your finger on the outer frame of your iPad, then swipe toward the middle of the iPad screen.
As you do this gesture, Luna Display’s sidebar will be unhidden.
Here there is quick access to the Display preferences and Arrangements. This sidebar also actively shows status of which connection is in use.
To hide the sidebar again, place your finger on the sidebar and swipe outwards from the iPad screen.
Wifi connection not available or unreliable? No problem! Plug your iPad-compatible USB cord into another Mac port, along side with Luna Display. This provides a constant, consistent connection with your devices.
Apple Pencil can be used with Luna Display, and will utilize basic input, as well as pressure sensitivity support.
If you are running macOS Mojave
Unlike other macOS versions, you will need to enable Accessibility to use Luna Display. There will be a message that prompts during initial setup, with steps to Enable Accessibility from your Mac's Systems Preferences.
You can also activate this manually by going to System Preferences, Security & Privacy, under the Privacy tab. There, check the box next to the Luna Display icon. If you don't see the Luna Display icon, click the "+" button and directly add the Application.
If you are running macOS Catalina
Along with the enable Accessibility that was introduced with macOS Mojave, a new permissions has been added. "Allow Screen Recording" needs to be enabled to allow Luna Display to access the content on your screen. Luna Display does not record the contents of your screen, but since it is acting as an additional display this permission is now needed.
There will be a message that prompts during initial setup, with detailed steps to Enable this from your Mac's Systems Preferences.
You can also activate this manually by going to System Preferences, Security & Privacy, under the Privacy tab. There, scroll for "Screen Recording" and check the box next to the Luna Display icon.
