Add Omarchy actions to the Apple Silicon Touch Bar

[austindixson]

Summary

On M-series MacBooks with a Touch Bar, tiny-dfr already paints the DSI strip, but the stock layout is F1–F12 until you hold Fn. This puts useful Omarchy actions on the default (no-Fn) row and lets users customize it.

Default strip (no Fn): brightness, Omarchy menu, terminal, lock, screenshot, mic mute, media transport, volume.

Fn: F1–F12.

Hardware setup is aarch64 + Apple device-tree only. T2 Macs keep the kernel Boot Camp Touch Bar and do not get tiny-dfr from this leaf.

Customize

Copy shell/plugins/touchbar/layout.json to ~/.config/omarchy/touchbar.json and save. The omarchy.touchbar service regenerates /etc/tiny-dfr/config.toml. Hand-written configs that are not Omarchy-generated are left alone.

Test plan

• ./test/shell.d/apple-touchbar-test.sh
• ./test/shell.d/hyprland-binding-conflicts-test.sh
• Lived on MacBookPro17,1 (M1 13" with Touch Bar): tiny-dfr running, layout installed locally first

Notes

tiny-dfr can only inject keycodes, not shell commands. Menu/terminal/lock are F13/F14/Search plus Hyprland binds in default/hypr/bindings/touchbar.lua.

Saving touchbar.json runs sudo from a detached Quickshell process with no terminal or pkexec, so it will usually fail silently once sudo credentials are cold. Route install/restart through a real privilege prompt and report failures; test this on an existing install too.

Addressed in 815aefc.

Saving ~/.config/omarchy/touchbar.json no longer sudos from the detached Quickshell process. apply.sh uses pkexec (polkit prompt) when there is no TTY, keeps sudo only for a real terminal, and does not swallow tiny-dfr restart failures. The service runs apply as a Process and fires a critical Omarchy notification on a non-zero exit.

Tests cover the detached pkexec path, skipping elevation when /etc/tiny-dfr/config.toml already matches (existing install), and a failed restart.

Thank you for the feedback. It is a big accomplishment to be accepted on Omarchy on mac, so i took a look at everything again and discovered some opportunities for meaningful improvement and submitted an update.
