Apple has released macOS Sequoia 15.3.1, and 14.7.4, 13.7.4
Apple has just released a security update to macOS Sequoia to bring it to version 15.3.1, and security updates for 14.7.4 and 13.7.4.
Sequoia 15.3.1 update for Apple silicon is about 1.43 GB in size.
Although these updates are listed on Apple’s security release notes page, they have no published entries, so there’s no information as to what they might address.
Apple silicon Macs have a firmware update, taking iBoot to version 11881.81.4.
The macOS build number is 24D70, and Safari remains at version 18.3 (20620.2.4.11.5). Messages has single minor build increment, but there are no other significant changes in bundled apps or in /System/Library.
I will update this as I get further information.
