“SpamSieve” is damaged and can’t be opened. You should move it to the Trash

I’m setting up a new Mac and reistalling all my applications but when I download SpamSieve I get this message: “SpamSieve” is damaged and can’t be opened. You should move it to the Trash. Using BigSur 1.0.1 Silicon MacMini

Do you get that error when opening the .dmg file or when double-clicking the .app file? Have you tried downloading a fresh copy using a different Web browser?

The message appears after I’ve opened the DMG and when I try to drag it to the Application Folder

Please go to System Preferences ‣ Security & Privacy ‣ General and make sure that App Store and identified developers is selected.

If the .dmg file is in your Downloads folder, you could try entering this Terminal command before opening the .dmg:

sudo xattr -rd com.apple.quarantine ~/Downloads

Or if the application is already in your Applications folder:

sudo xattr -rd com.apple.quarantine /Applications/SpamSieve.app

You can re-download the app using this command in Terminal:

cd ~/Downloads/ && curl -LO 'https://c-command.com/downloads/SpamSieve-current.dmg'

and this will avoid the problematic quarantine attribute that browsers like Safari add.

It may also help to restart your Mac.

Thanks Michael,
Terminal seems to have fixed the problem.

Stay safe and Happy Holidays,

We now offer a Download Fixer tool. If you get the “SpamSieve” is damaged and can’t be opened. You should move it to the Trash error message, you can just double-click the tool and it will verify that SpamSieve is not damaged and fix it so that macOS no longer reports the error.
