Installation

- 2. Remove the quarantine flag. Open Terminal and run:
xattr -cr /Applications/Splitwave.app - 3. Launch Splitwave from Applications.
Why is this needed?
Splitwave is an open-source app distributed outside the Mac App Store and is not yet notarized by Apple. When you download a file from the internet, macOS attaches a com.apple.quarantine attribute to it. Because the app isn't notarized, Gatekeeper blocks it with a “Splitwave is damaged and can't be opened” or “unidentified developer” message. The xattr -cr command clears those extended attributes (-c clears, -r applies recursively), which removes the quarantine flag so macOS lets the app run. It does not modify the app itself.
