How to prevent Google Chrome extension pop-ups on a Mac

Following the update of Google Chrome to version 79, the web browser no longer remembers your preferences for opening external applications. This article demonstrates how to recover this functionality.

Re-enabling external application preferences on a Mac requires administrator access and needs to be performed within Terminal. Whilst the process is relatively simple, if your IT systems are managed by a dedicated team they should be consulted.

1) Open the Terminal application on your mac.

2) Type: sudo -s

3) Press Enter. Your may now be asked for you admin password, type this in and press Enter again.

4) Type: nano /Library/Preferences/

5) Press Enter.

6) Copy and paste the following text into the Terminal screen:

<?xml version=“1.0” encoding=“UTF-8"?>
<!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “”>
<plist version=“1.0”>

7) Press CTRL+O

8) Press CTRL+X

9) Restart Google Chrome.


After these steps have been completed, the next time you click on a number using Click to Call, the pop-up will have a check box to "Remember this option", checking this box will stop the pop-up being displayed for future calls.
