Installation

Via Homebrew (Recommended)

brew install --cask larskemper/cask/system-stats

Manual Installation

Download the DMG for your architecture:

• Apple Silicon: system-stats-aarch64.dmg
• Intel: system-stats-x86_64.dmg

macOS Quarantine Flags

The distributed DMG files are built without macOS quarantine flags, so they should install without Gatekeeper warnings.

If you encounter a "cannot be opened because the developer cannot be verified" message, you can manually remove the quarantine flag:

# Remove quarantine from the app
xattr -dr com.apple.quarantine "/Applications/System Stats.app"

# Verify removal (should return "No such xattr" or no output)
xattr -l "/Applications/System Stats.app"

Then try opening the app again.
