Apple has released Sequoia 15.0.1 and Safari updates

Overnight European time, Apple released a small but urgent update to macOS Sequoia, bringing it to version 15.0.1. Although there are no updates to Sonoma or Ventura, there are updated versions of Safari for both.

This Sequoia update is about 1.42 GB for Apple silicon Macs, and around 500 MB for Intel models. It doesn’t bring any firmware updates, but Safari is updated to version 18.0.1 (20619.1.26.31.7). While Apple has released security notes for the concomitant updates for iOS and iPadOS, there are none reported for macOS.

Although Apple remains tight-lipped about exactly what has been fixed in this update, it does admit to fixing a bug in Messages that could crash the app in unusual circumstances, and to improving “compatibility with third-party security software”. It’s assumed the latter refers to the network problems that have been widely reported.

I’ll update this article soon with information about what this update does change.
