This is how I do it: 1. Open Automator app and create a new "Workflow" 2. Search for action "Run AppleScript" and drag it to the main pane on the right 3. Paste the following script into it: tell application "System Preferences" reveal anchor "trackpadTab" of pane id "com.apple.preference.trackpad" activate end tell tell application "System Events" tell process "System Preferences" click radio button "Scroll & Zoom" of tab group 1 of window "Trackpad" click checkbox 2 of tab group 1 of window "Trackpad" end tell end tell tell application "System Events" tell process "System Preferences" click radio button "Scroll & Zoom" of tab group 1 of window "Trackpad" click checkbox 2 of tab group 1 of window "Trackpad" end tell end tell tell application "System Preferences" quit end tell 4. Save as Workflow and place the file somewhere it won't move. 5. Still in Automator, create new "Application" 6. Search for action "Run Workflow" and drag it to the right 7. On the first line "Workflow:", click on the dropdown menu and select "Other..." 8. Browse for the workflow file you created earlier 9. Save as Application and place anywhere you want. 10. Open System Preferences > Security & Privacy > Accessibility, unlock the padlock (bottom left), click on the + button and browse to the application file you created (not the workflow file). At this point you want to make sure the checkbox for the application is also ticked. From now on, anytime the Pinch & Zoom disables itself, just run the app and it will do the job seamlessly. You can keep the app in your dock, or assign it a keyboard shortcut. I use BetterTouchTool for that. What the script does: Open System Preferences > Open Trackpad pane > Open Scroll & Zoom tab > Click on "Zoom in or out" twice > Quit System Preferences
