macOS Simulate key to activate Caps Lock

[CMT]

Is there any way to simulate a key press in order to activate/deactivate CapsLock programmatically?

I've been searching for simulating keys but caps lock remains untouched.

This shows how to detect caps lock being pressed

This shows how to create a low-level key event.

I'd have though that you could combine these to do what you want…


Edit: or not. Having read the first link it may not be possible without interfacing with the keyboard driver...

Indeed the author says at the end:

I'm looking myself for a way to programmatically toggle capslock on Mac, without success so far. But I can assure you, event taps are not the way to go.

Looks like it will not be that simple. Maybe it's time to give a try to AppleScript?

Thanks robbieduncan

You could try this. But installing a custom keyboard driver does seem a touch extreme..

Hmm, quite extreme. Anyway, I don't think it's an interesting idea to ask users (from my app) to install such keyboard hack…

Back to AppleScript, looks like

key code

could solve the problem (Help Library > System Events > Processes Suite > key code). The only problem is that I need to know how to use this, AppleScript is not one of my strengths.

Back to google…
