What has changed in macOS Ventura 13.3?

The update to macOS Ventura 13.3 is substantial, and brings many improvements and fixes, including the following listed by Apple:

  • A remove background option in Freeform to automatically isolate a subject.
  • Duplicate detection in Photos now includes iCloud Shared Photo Libraries.
  • A new Accessibility setting to automatically dim video containing flashing light and strobe effects (referred to in private libraries as photosensitivity).
  • A fix to Trackpad gestures ceasing to respond.
  • A fix to VoiceOver, that could become unresponsive after using the Finder.
  • Even more (21) new emoji, just what we all wanted.

Beta-testers report that this fixes the bug connecting to SMB shares with custom icons. Michael Tsai of C-Command points out that Mail plug-ins need to be updated for 13.3, as he has already with a new version of the mighty SpamSieve.

A full list of security vulnerabilities addressed is here. It includes 49 items, with four fixes to the kernel, although Apple hasn’t noted any as being exploited in the wild yet.
