Apple has released updates to macOS, to bring Tahoe to version 26.3, and security updates for Sequoia to version 15.7.4, and Sonoma to 14.8.4.

The Tahoe update downloads in around 3.7 GB for an Apple silicon Mac, and 2.5 GB for an Intel Mac.

Apple seems to have forgotten what 26.3 fixes or improves, writing just “this update provides important bug fixes and security updates”.

Security release notes for Tahoe 26.3 are here, and list around 52 vulnerabilities addressed, including one that has been previously used in an attack on iOS. Sequoia 15.7.4 has about 30 fixes listed here, and Sonoma 14.8.4 has about 36 listed here.

The build number of 26.3 is 25D125, and iBoot firmware is updated to version 13822.81.10. Safari is version 26.3 (21623.2.7.11.6).

I’ll update this post with further information as I get it. and will later provide details of significant changes in version numbers.
