Hello,
When I attempt to download 3.0.2 and move it to applications folder, I’'m told the file is damaged.
MacOS 14.11 on MacBook Air.
What to do?

When you double-click the application file to launch it, macOS may erroneously report:
- “‘SpamSieve’ is damaged and can’t be opened. You should move it to the Trash.”
- “‘SpamSieve’ cannot be opened because the developer cannot be verified. macOS cannot verify that this app is free from malware.”
The app is unlikely to be damaged because the SpamSieve-3.0.2.dmg file opened and mounted without error. The SpamSieve application file is signed with a Developer ID certificate and notarized by Apple. If desired, you can manually verify this, which will also check that the app is not damaged. Instead, what seems to be happening is that macOS is getting confused by some metadata that was added to the SpamSieve-3.0.2.dmg file when your Web browser downloaded it. Either the metadata is incorrect, or macOS is encountering an error when verifying it (perhaps due to a temporary problem with Apple’s servers).
You can work around the problem by downloading the app in a different way (which avoids the metadata). First, open the Terminal app in the Utilities folder in your Applications folder. Then enter this command (all on line line) and press Return.
cd ~/Downloads/ && curl -LO 'https://c-command.com/downloads/SpamSieve-current.dmg'
