Apple Seeds Third Beta of macOS Sonoma 14.3 to Developers

Tuesday January 9, 2024 10:06 am PST by Juli Clover

Apple today seeded the third beta of an upcoming macOS Sonoma 14.3 update to developers for testing purposes, with the software coming a week after the release of the second macOS Sonoma 14.3 beta.

Registered developers can opt-in to the beta through the Software Update section of the System Settings app. Under Beta updates, toggle on the macOS Sonoma Developer Beta. Note that an Apple ID associated with an Apple Developer account is required to get the beta.

We don't yet know what features are included in macOS Sonoma 14.3, and there were no notable changes discovered in the first two betas, so we may not know what's new until the software comes out and is accompanied by release notes.

ProMotion support would have allowed for the iPad mini's refresh rate to automatically adjust from 10Hz to 120Hz depending on the content being displayed, but evidently Apple has kept the feature exclusive to the iPad Pro among iPad...

Just noticed that one Safari issue I had for a very long time changed recently, possibly with this beta.

That is that you could not sign into Netflix while using private window mode with Apple's tracking and privacy preserving measures active. Now I can.

Neither of my M1 MacBook Pro (16 and 14in) can see the update at 2:25PM Eastern

Axel F.

3:56pm ET and still not seeing anything. Have m1 iMac, M1 MBA, M2MBA and M3 MBP. None showing any available updates. All are on beta 2 (23D5043d). These beta rollouts are becoming more haphazard lately. Usually they were available about 30min after being announced, last couple are taking hours.
