Installation
- 1 Open the .dmg and drag Splitwave into your Applications folder.
- 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.
Support
If you find Splitwave useful, consider supporting its development with a crypto donation. Thank you!
