Toggle Mac Display HDR

This AppleScript allows you to automate the toggling of using HDR of a display on MacOS. Useful when switching between watching HDR content (youtube, apple tv) to using regular applications.

Essentially it does the job one would have to do manually: Open System Preferences, go to Displays, click "High Dynamic Range".

Tested with:

• MacOS Ventura (13.4.1(c)) August 2023

Instructions for use

1. On your mac, open Script Editor
2. Copy / paste the contents of Toggle Display HDR.scpt
3. File Save / Hold option: File, Save As
4. Save the script as an application:
   1. Choose filename (e.g. "Toggle Display HDR")
   2. File format: Application
   3. Save to Applications Folder
5. Double click from the applications folder
6. Enable the script to be run by going into System Preferences, Security & Privacy, unlocking the dialogue box, then selecting (usually in Accessibility) Toggle Display HDR and whatever else it needs to run.

Running

For me, the easiest method I've found is to use cmd + space to search for "Toggle Display HDR" and run it from there, or drag the application to the dock and click to trigger it.
