SpamSieve Public Beta and macOS 12 Monterey

The current public beta version of SpamSieve is compatible with Apple Mail on the beta version of macOS 12. You can sign up below to be notified when new beta versions are available and download them from within the app.

The beta release notes are available in the Software Update window and also in the “Version History” section of the manual (in the Help menu).

We do not recommend using a macOS beta on your main Mac, as there may be bugs that we have not had time to, or cannot, work around. With that said, we do welcome bug reports so that we can investigate any bugs and report them to Apple or try to develop workarounds. Please submit any feedback or bug reports via e-mail, rather than posting here.


SpamSieve 2.9.44b2 is now available and works with macOS 12 Developer Beta 1.

Michael, Thanks, I wasn’t worried. Every year your team usually comes up with a solution within 72 hours of release

this time, my implementation took a couple tries before the update took, but it seems OK now


Thanks Michael - as per your advice I had to additionally delete the bundles folder. I restarted to make sure, enabled the plugin again and all is now back to normal.
