Updates

Once installed in Applications, QCView keeps itself up to date — it checks once a day and offers to download and install new versions in place. You can also check any time from About → Check for Updates…, or turn automatic checks off in Settings → Updates. (In-place updates require running QCView from the Applications folder, not from the mounted disk image.)

Requirements
