macOS quarantines apps downloaded outside the App Store. You have two ways to allow Rumus to run:Option 1 — Run the xattr command (recommended). Open Terminal and paste:
xattr -cr /Applications/Rumus.app
This clears the quarantine attribute on the app bundle. You’ll need to run it again after every update.Option 2 — Allow through System Settings. Open System Settings → Privacy & Security, scroll to the Security section, and click Open Anyway next to the message about Rumus.
System Settings doesn’t always surface the Rumus prompt — especially if you closed the initial dialog. If you can’t find it, just run the xattr command above.
Rumus uses the system WebView2 runtime to render its UI. Windows 11 and recent Windows 10 builds ship it by default. If your machine doesn’t have it, the installer prompts you to install it. You can also install it manually from the WebView2 download page.
The fastest way to install Rumus on Linux is the official script. It detects your distribution and architecture and installs the matching package (.deb, .rpm, or .AppImage):
Prefer to grab the package yourself? Each release also offers direct downloads on rumus.ai/download:
Format
Architectures
Use for
.AppImage
x64, ARM64
Any distro — no installation, just chmod +x and run
.deb
x64, ARM64
Debian, Ubuntu, Mint
.rpm
x64, ARM64
Fedora, RHEL, openSUSE
AppImage example:
chmod +x rumus.AppImage./rumus.AppImage
Linux builds require webkit2gtk-4.1 and libgtk-3. Most desktop distributions ship these by default; install them with your package manager if Rumus fails to launch.
Rumus checks for new releases on launch. How updates are applied depends on your platform:
macOS and Windows — when an update is available, Rumus offers to download and install it automatically. You’ll see a dialog with options like Download & Install, View Changelog, or Visit Download Page.
On macOS, remember to run xattr -cr /Applications/Rumus.app again after each update.
Linux — auto-install is not supported. Rumus notifies you when a new version is out, and you upgrade by re-running the install script:
curl -f https://www.rumus.ai/install.sh | sh
Or by downloading the latest package from rumus.ai/download and installing it through your package manager.
Open Settings → Apps → Installed apps, find Rumus, and uninstall. To clear user data, also remove %APPDATA%\ai.rumus.terminal.
Use your package manager (apt remove rumus / dnf remove rumus). For AppImage, just delete the file. User data lives at ~/.config/ai.rumus.terminal.
Before uninstalling, back up your vault secret key if you’ve enabled vault sync. Without the key, encrypted data in the cloud cannot be recovered. See Account & Sync for details.
