Apple has released macOS Big Sur 11.6.7 to the public with a fix for email attachments.

The macOS Big Sur 11.6.7 release arrives during Apple's busy WWDC week with a small bug fix. Mail and apps like Outlook would run into an error when opening attachments, and that has been addressed.

It isn't clear if there are other fixes included in this update. Since macOS Big Sur is an older operating system, Apple only provides necessary bug fixes and patches holes in security form time to time.

Apple last provided an update to macOS Big Sur in May with the release of macOS Big Sur 11.6.6, which addressed bug fixes and potential security issues. Prior to that, Apple updated the macOS Big Sur platform in March with other bug fixes.

The build number for macOS 11.6.7 is 20G630, up from 20G623.

Apple first released macOS Big Sur in November 2020. The update brought a number of major changes to the Mac operating system, including a user interface redesign and support for Apple Silicon.

    Big Sur 11.6.6 caused the mail attachment bug.  A permissions error appeared when trying to open an attachment in Mail and Outlook.  Caused a lot of IT calls for those that had not yet upgraded to Monterey.  So the solution is 11.6.7 or Monterey 12.4.
