Frequently Asked Questions

Why did Antidote 10 stop working with Mail after I updated macOS?

The macOS Sonoma operating system, released September 26, 2023, exclusively uses the MailKit extension framework for its native email client. This change renders older editions of Antidote incompatible with Mail.

If you are subscribed to Antidote+, you are entitled to all updates and upgrades free of charge. If you have not already installed Antidote 11 on your computer, you can do so now to take full advantage of everything the most recent editions of macOS and Antidote have to offer.


Otherwise, you can claim your upgrade privileges to get a substantial discount on the purchase of Antidote 11 or a subscription to Antidote+.
