Who can join
Android testers must have both a Mac and an Android device. The Mac sends the extended display, and the Android device receives it.
The test period is 14 days. During that time, please try normal extended-screen workflows and report whether setup, connection, and display behavior work correctly.
DeskJoin Screen for Android is limited to the extended display feature during this test. It does not collect user data, does not upload screen content, and does not add analytics inside the app.
