What has changed in macOS Sonoma 14.5?

macOS Sonoma 14.5 build 23F79 is a relatively small update, with limited changes listed by Apple. Its brief release notes identify two enhancements in Apple News+, bringing Quartiles, a new word game, and Scoreboard in Puzzles. In its developer notes, Apple states that this update should also fix a problem in which users were unable to approve or decline FaceTime link calls because of a failure in notifications.

Security release notes for 14.5 list 22 vulnerabilities addressed, among them two in AMFI and one in the kernel. Apple doesn’t identify any as being known to be exploited yet.

There are small firmware increments for some Macs, at least. iBoot is updated to 10151.121.1, and Intel Macs with T2 chips have an iBridge update, bringing their firmware to 2022.100.22.0.0 (iBridge: 21.16.5077.0.0,0).
