Before Macbook can be remotely controlled, it needs to give 「Full Disk Access」、「Accessibility」、「Screen recording」 permission to DeskIn. Please go to Macbook System Settings >> Privacy and Security to check whether these three permissions are authorized for use by DeskIn.

Click to enter 「Full Disk Access」,「Accessibility」, 「Screen recording」 settings, if DeskIn is in the list and the button on the right is toggled on, it means DeskIn has been authorized this permission. If DeskIn is not found in the list, please click the + sign in the lower left corner, find DeskIn and add it to the list, and enable the authorization phenomenon on the right.
