macOS 26.1: Add screen recording permission
After installing the macOS driver, if extended display does not work, grant Screen & System Audio Recording permission to MacUsbDisplay as follows.
Step 1: Open Screen & System Audio Recording settings
Go to System Settings → Privacy & Security → Screen & System Audio Recording.
You should see the allow list (it may be empty at first):
Step 2: Open the folder containing the driver files
In Finder, choose Go → Go to Folder… (Shift + Command + G) and enter:
/usr/local/bin
This folder contains the MacUsbDisplay executable (and usbdisplay_uninstall, etc.).
Step 3: Drag MacUsbDisplay into the list and confirm
Drag MacUsbDisplay into the Screen & System Audio Recording app list. Enter your administrator password when prompted and click Modify Settings.
Once added, MacUsbDisplay appears in the list and display extension should work. If not, reconnect the device or restart and try again.
