When there’s a new version of the operating system, SpamSieve typically needs an update for compatibility with the new version of Apple Mail. Mail will present an error saying:
We make a public beta version of SpamSieve available for compatibility with the latest macOS beta:Mail has disabled the following plug-ins:
Contact the makers of these plug-ins for versions that are compatible with Mail 10.0.
- Click this link (after installing SpamSieve) to join the public beta program and receive updates via the built-in Software Update… command.
- Click this link to stop receiving beta updates.
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.
When the new version of macOS is finalized and released to everyone, we (usually within hours) test SpamSieve with the release version and finalize the new version of SpamSieve. The new version is announced on the SpamSieve mailing list, blog, and Twitter feed and becomes available via the Software Update… command. It’s best to update SpamSieve before updating macOS. To prevent macOS from updating itself without asking you, go to the App Store section of System Preferences and make sure that Install macOS updates is unchecked.
Apple Mail under macOS 10.12 Sierra Developer Preview 1 (16A201w) is not yet supported. This thread will be updated as new information becomes available.
