Solution for Screen Mirroring timeout on macOS 15+

If you’re using macOS 15 or later and encounter the error:
“Pairing timed out! The receiver did not accept the pairing request. Please try pairing again.”
—even when both devices are connected to the same Wi-Fi network—the issue is likely caused by macOS 15+’s Local Network permission restrictions.

How to Fix It

Run the following commands in Terminal to reset network permissions:

sudo rm /Library/Preferences/com.apple.networkextension.plist  
sudo rm /Library/Preferences/com.apple.networkextension.uuidcache.plist  

Then restart your Mac.

⚠️ Important:
After rebooting, if macOS prompts for Local Network access, make sure to click “Allow” to grant permission.
