I have this done in Swift here, using the private MonitorPanel.framework: https://github.com/alin23/mac-utils#togglehdr
No need for scripting the UI anymore ^_^
I also provide it as an Apple Shortcut in 🌕 Lunar in case you already have that installed:
@alin23 awesome, thank you! I dumbed down your Swift script even a bit, so that it just activates HDR where applicable in a "fire & forget" fashion. This way, I can directly call it from the Shortcuts app. Works great.
You could also give a heads up to the displayplacer guys at jakehilborn/displayplacer#27, given that the one thing stopping them from adding HDR support to this tool is lack of a "known" API to control HDR settings.

How do I use your program? Do I have to compile it into a program?
If you know how to use the command-line, you can download the compiled binary and just run it:
bin="$HOME/.bin/ToggleHDR"
if [[ ! -d "$HOME/.bin" ]]; then
mkdir -p -m 0755 "$HOME/.bin"
fi
if [[ ! -f $bin ]]; then
curl -L https://raw.githubusercontent.com/alin23/mac-utils/main/bin/$(basename $bin) -o $bin;
chmod +x $bin;
fi
$HOME/.bin/ToggleHDRWhich will output something similar to:
ID UUID HDR Control Name
1 37D8832A-2D66-02CA-B9F7-8F30A301B230 false Built-in Liquid Retina XDR Display
2 3B300CA4-8F5F-4E77-A757-CFD72454C30A true LG Ultrafine
Usage: $HOME/.bin/ToggleHDR <id-uuid-or-name>If you're not comfortable with the command-line, I advise downloading Lunar from https://lunar.fyi/ and using the Toggle HDR action through Apple Shortcuts.
Here's an already made shortcut to get started:
Well, the adapted "fire & forget" version would still need to be compiled.
- install Xcode
- clone the repo (
git clone git@github.com:skempken/mac-utils.git) - run
make - find the binary in
./bin/EnableHDR - create a Shortcut with a single Shell script action, running the binary from the previous step
- profit 😉
@alin23 your program does a toggle, i was wondering if it was possible to a force on, so if it was on, it would be left alone, but if it was off, it would be turned on.. is that possible?

Yes, I just added that a few minutes ago. You can download the updated binary.

how do i do this, his script requires the uuid of the monitor, so it needs an argument.

Hi, sorry, the ToggleHDR binary still does a toggle action. Not force on.
@alin23 See here for the "fire & forget" mode binary, which just turns on HDR on all applicable monitors, no questions asked: https://github.com/skempken/mac-utils/blob/enableHDR/bin/EnableHDR
@skempken it works perfectly, do you mind sharing the code so that I can just save my UUID into the program and compile it?

Most likely you haven't updated the binary. See below how it works:

See this PR alin23/mac-utils#5
Unfortunately not. My best guess would be to attach a debugger to the running System Settings process and look through the call stack when clicking on the HDR toggle. But I've never done such a thing before.
