Codebook for macOS 4.5.11 is [now available for download](https://www.zetetic.net/codebook/download/macos/). This update is a maintenance update that fixes a bug during sync with Google Drive (a 404 error) which recently started occurring due to changes in the behavior of the Google Drive service.

**Please note** : This update requires a [minimum macOS version of 10.15 Catalina](https://discuss.zetetic.net/t/codebook-ending-support-for-macos-10-12-through-10-14/5696), and will not launch on earlier versions of macOS.
