Apple has released macOS Sequoia 15.4, and 14.7.5, 13.7.5
Apple has just released the update to macOS Sequoia to bring it to version 15.4, and security updates for 14.7.5 and 13.7.5.
The Sequoia update for Apple silicon Macs is about 6.2 GB in size, and 3.2 GB for Intel models, making it one of the largest intermediate updates.
Among the changes listed by Apple for 15.4 are:
Adds Memory movies in Photos using AI.
Adds a Sketch Style option in Image Playground, in AI.
Adds Mail Categorisation.
Apple silicon Macs with an internal SD card reader now support SDUC cards larger than 2TB.
This should resolve problems with some M4 Macs being unable to launch Virtual Machines.
Security release notes are available for Sequoia, Sonoma and Ventura updates. There are a total of around 128 vulnerabilities fixed in 15.4, which must be a record. None is reported as being suspected of exploitation in the wild.
I will post further details as I get them.
