Apple has just released the update to bring Sonoma to version 14.6, together with security updates to Ventura (13.6.8) and Monterey (12.7.6). I expect that there will also be a separate update to Safari for Ventura and Monterey.

The 14.6 update is around 2.2 GB for Apple silicon Macs, and 1.8 GB for Intel models.

iBoot firmware for Apple silicon Macs is updated to version 10151.140.19, firmware of Intel Macs with T2 chips is updated to version 2022.140.5.0.0 (iBridge: 21.16.6074.0.0,0), and Safari to version 17.6 (19618.3.11.11.5).

Significant bugs fixed include app crashes when running iPhone and iOS apps on Apple silicon Macs, and a complex bug in video decoding in which the hardware decoder wasn’t used when it should have been.

Security release notes for Sonoma reveal a total of 54 vulnerabilities have been addressed, including several in open source code, but none is reported as having been known to be exploited yet. Those for Ventura list 36, and for Monterey 32.

I’ll update this article with further details as they arrive.
