macOS — “damaged” warning? CatDeck is not yet signed with an Apple Developer certificate, so macOS Gatekeeper may block it with a “damaged and can’t be opened” message. The file is fine — this is a Gatekeeper quarantine flag. To open it, run this command in Terminal after downloading: xattr -dr com.apple.quarantine ~/Downloads/CatDeckSetup-*-mac.dmg Then open the DMG and drag CatDeck to Applications as normal. Alternatively, right-click the DMG and choose Open, then click Open in the dialog.
