TouchBar v0.1.0

First tagged release of the TouchBar runtime and plugin platform.

This tag is the SDK toolchain reference. touchbarctl plugin new scaffolds packages that depend on touchbar-component-sdk from this repository at this tag, so it must exist for a scaffolded plugin to build.

What's here

• touchbard — privileged hardware service owning DRM, raw touch and Fn input, backlight policy, and a restricted uinput keyboard
• touchbar-sessiond — per-user GPU compositor and policy engine owning profiles, layout, themes, plugins, and interaction
• touchbarctl — the administrative and plugin-authoring CLI
• A WebAssembly component plugin host and capability supervisor with 13 scoped capabilities and an append-only audit log
• A retained UI kit, package and catalog formats, a content-addressed plugin store
• A deterministic replay harness with typed fixtures for every capability
• An onscreen compositor simulator — touchbarctl plugin dev renders the real compositor's scene in a desktop window, so plugin development needs no Touch Bar hardware

Installing

There is no binary artifact yet; build from source, or use the Arch PKGBUILDs under packaging/aur/. Installation is inert — taking over the Touch Bar is a separate touchbar-activate, and touchbar-rollback hands it back to tiny-dfr.

Hardware

Verified on Apple M1 (MacBookPro17,1). Apple M2 (Mac14,7) is expected to work but is unverified. The Intel T2 (appletbdrm) presentation path is implemented but not yet hardware-verified.

Physical presentation is currently limited to ~29.9 Hz by the experimental ADP kernel driver; plugin rendering and compositing run at 60 FPS.
