MAL Library 2.1.1 is now released on the App Store as a free update along with users who didn’t download it outside the App Store. This fixes a content-type accept bug that prevents the functionality of MAL Library from working, especially on High Sierra developer preview. Note that macOS High Sierra has not released to the public, meaning that any developer preview updates might break MAL Library.
You can download MAL Library at the official website. Below is the changelog.
- Fixed rare instance where lists, title information, search or messages will not load due to content type mismatch.
