macOS: "Sovernote is damaged and can't be opened"?
Sovernote is currently in Preview and not yet notarized with Apple, so macOS Gatekeeper
quarantines the download. To open it, run this once in Terminal after moving the app to your
Applications folder:
xattr -cr /Applications/Sovernote.app
Alternatively, on macOS Sequoia (15+): open
System Settings → Privacy & Security, scroll to the bottom, and click
"Open Anyway" next to Sovernote.
Full notarization is planned before the public release.
