iDisplay
iDisplay is a utility app from SHAPE Services that turns an iPad, iPhone, or iPod touch into a secondary display for a Mac. Users connect their mobile device via USB cable or Wi-Fi and can either extend their Mac desktop to the mobile screen or mirror it, enhancing productivity by expanding workspace. The app requires both a paid mobile app (purchased on the App Store) and a free desktop component installed on the Mac, and supports Retina displays and multiple connected devices simultaneously.
AI Recommendation
1 suggestionThe latest publicly documented version of iDisplay Desktop is 1.4, released many years ago, with no official sign of active development by SHAPE Services in recent years. Search results indicate compatibility statements for macOS going back to OS X 10.9, but no native Apple Silicon build has been confirmed. iDisplay will continue to run under Rosetta 2 on your Mac today, but Apple is removing Rosetta in macOS 28 (late 2027), at which point this Intel-only app will stop launching. Before that date, contact SHAPE Services directly to ask whether a native Apple Silicon build is planned; you can find the vendor's current contact information through their website at getidisplay.com. If they confirm no native version is coming, you will need to migrate to an alternative remote-display solution—consider alternatives like Luna Display (which supports Apple Silicon and uses a hardware dongle to extend to a second monitor), Sidecar (Apple's built-in feature for using iPads as external displays, though with limitations), or Duet Display (which also offers native Apple Silicon support and works over USB or Wi-Fi), depending on your specific needs.
