Install

Loom ships as a .dmg from GitHub Releases. macOS 14 (Sonoma) or later.

Steps

1. Grab the latest Loom-<version>.dmg from Releases.
2. Open the DMG.
3. Drag Loom onto the Applications alias inside the mounted volume.
4. Eject the volume.

First launch — Gatekeeper

The build is ad-hoc signed, not Developer ID-signed. macOS will refuse to launch it on the first try with a "Loom can't be opened because Apple cannot check it for malicious software" dialog.

Bypass once:

• Right-click Loom in /Applications → Open → confirm in the dialog.

Subsequent launches are normal. Only the first launch needs the bypass.

Updates

Once Loom is running, it polls GitHub Releases on a 60-second interval and stages new builds in the background. When a newer release is available, the Update pill in the top bar lights up — click it to swap in the new version. See Auto-update for the mechanics.

You can also force a remote check via Help → Check for Updates….

Uninstall

Drag /Applications/Loom.app to the Trash. Loom's data lives in:

• ~/Library/Application Support/Loom/ — staging directory and update manifest.
• ~/Library/Containers/ — none; Loom is unsandboxed.
• ~/Library/Application Support/com.chasesims.Loom/ — SwiftData store (workspaces, tasks, notes).
• macOS Keychain, service com.chasesims.Loom — Anthropic API key, local-endpoint auth tokens.
