Apple Seeds Updated Third Beta of macOS 14 Sonoma to Developers

I'm suspecting with only surface features, this might launch earlier this fall than past releases, which could suggest M3 iMac is close by.

You need to use MacOS 14 before trying to spin that rumor. :D

Comparison of original DB3 and this 2nd DB3 release (nothing changed aside from build from these 3 parameters)

macOS 14 beta 3 (23A5286i)

* Safari Version 17.0 (19616.1.20.11.3)
* System Firmware Version: 10151.0.172.0.3 (M1 based Macs)
* Darwin Kernel Version 23.0.0: Fri Jun 30 17:48:23 PDT 2023; root:xnu-10002.0.168.505.3~1/RELEASE_ARM64_T8103 arm64

macOS 14 beta 3 (23A5286g)

* Safari Version 17.0 (19616.1.20.11.3)
* System Firmware Version: 10151.0.172.0.3 (M1 based Macs)
* Darwin Kernel Version 23.0.0: Fri Jun 30 17:48:23 PDT 2023; root:xnu-10002.0.168.505.3~1/RELEASE_ARM64_T8103 arm64

So aside from security patch incorporated looks like a prelude to PB.

I'm assuming this just containts the RSR from yesterday.

There's something very weird going on in the background - M1 MacBook Pro I'm testing on is HOT all the time and the battery drains 100 to 0 in about an hour which is insane for it. Restarts don't fix it and Activity Monitor shows kernel_task taking many thousands CPU% constantly. Which makes it very laggy. This has been on all betas of this version. Could be a rare thing affecting me, but I don't think it's stable if that's happening.

Have you booted up in safe mode?

Start up your Mac with Apple silicon in safe mode
[LIST=1]
* On your Mac, choose Apple menu > Shut Down.
Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.
* Press and hold the power button on your Mac until “Loading startup options” appears.
* Select a volume.
* Press and hold the Shift key, then click Continue in Safe Mode.
The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.

I don't like that the laptop is running hot all the time. Sounds like some kind of hardware failure more than software. have you also ran diagnostics? If backed up you can also take this to the Apple store and have a DFU restore done to it.

Apple silicon
[LIST=1]
* Press and hold the power button on your Mac. (Every Mac has a power button. On laptop computers that have Touch ID, press and hold Touch ID.)
* As you continue to hold the power button, your Mac turns on and loads startup options ('https://support.apple.com/kb/HT211873'). When you see Options, release the power button.
* Press and hold Command (⌘)-D on your keyboard.

Guys, is it snappier than Ventura?
