Release status, system requirements, and what the signed Capslock release will contain.

No public download yet

Capslock 0.4.0 is a release candidate in final acceptance. A download link will appear here only after the release is Developer ID signed, notarized, installed on a clean account, smoke-tested on Intel and macOS 14, and its update feed is verified. Until then there is no official build to download.

Signed DMG

Pending release

Universal (Apple silicon and Intel) · macOS 14 Sonoma or later · Developer ID signed and notarized

Homebrew Cask

Pending release

Published with the same DMG once the tap location is approved; updates stay with the in-app updater.

System requirements

macOS 14 Sonoma or later.
A Mac with Apple silicon or an Intel processor. The app is a single Universal build.
The Accessibility permission. Capslock does not ask for Input Monitoring.
Nothing else is installed: no kernel extension, DriverKit driver, root daemon, or privileged helper.

If Karabiner-Elements or another remapper already maps Caps Lock, Capslock reports the conflict and does not start until you resolve it. See Coexisting with Karabiner-Elements.

What the release contains

Capslock.dmg, containing Capslock.app, signed with Developer ID, notarized by Apple, and stapled so it opens without a Gatekeeper warning.
In-app updates through Sparkle, over HTTPS, from an EdDSA-signed feed. Local and development builds contain no update feed and never check for updates.
A Homebrew Cask generated from the same DMG. It quits Capslock on uninstall so the app can remove its own Caps Lock mapping.

Once you have the DMG, follow Install and first run.

Looking for the Karabiner configuration?

Before the native app, Capslock was a configuration file for Karabiner-Elements, and it is still published, free and open source, as the Karabiner Edition. Import it in one click from Install. The native app builds the same layout in: you do not need Karabiner-Elements to use it, and you should not run both on Caps Lock at the same time.
