Is there any ETA for this beta to go officially live as a standard update procedure ?
Are there still some things that needs to be done to release this version ? 😃

[HunterAhlquist]

It seems there's an issue with the auto update and auto start preferences on this beta. It keeps downgrading to 1.5.16 every time I reboot (quitting and starting it doesn't seem to trigger it.) The auto login checkbox appears to not be functional, clicking on it just keeps it unchecked.
Everything else works good though!

Does the beta still have this problem for users of M3 series processors, or is it just me who is lucky?

I'm curious if people who reported regaining control of their fans in Sonoma 14.4 still have it in 14.5? @HunterAhlquist

Just want everyone to keep in mind, I'm not a dev or even a volunteer, just sharing what worked for me.
I can still control my fans in 14.5 but, there's an (intentional?) issue with the current M3 SMC (fan controller) where it wont even turn on the fan until a threshold is passed hard-coded.
Don't think there is any way around that unless Apple changes it.

[au-ganymede]

Of course, I tagged you because you reported that the beta version worked fine on your system, or at least I thought it did. And I wondered if it also worked on the latest version of the system.

[HunterAhlquist]

Yes it still works for me in 14.5
Remember to turn off auto-update, I had to set the settings in the current version, then upgrade to the beta. It'll downgrade back to the current version if you don't.

[au-ganymede]

OK, thank you for the information. Just clarifying, because I'm not sure I understood correctly. You can de facto control the speed of the fans only and only when the computer is under load? For example, the CPU/GPU temperature starts to exceed 80 degrees, the fans start up and then you can adjust their speed? If the temperature drops then the fans switch off? Or does the RPM you set still apply?

[HunterAhlquist]

Yeah, that's how it's been working for me.

1.5.16 was working fine for me on M3 Max
Untill I updated to the MacOS 15 Beta.
Fan control has been lost for me with this OS update.

macOS Sequoia Preview?

macOS Sequoia Preview?

Version 15.0 Beta (24A5264n)

This should perhaps help:

macOS Sequoia Preview?

Actually I take that back. It is working fine again.
No idea what caused it to stop or re-start - the sensor temp was higher than the threshold.

Perhaps you can tell from the logs why it was not working temporarily.

I'd place my bet on Apple tweaking the fan control thresholds again.

[brokenalarms]

any timeline for when this will be integrated into main so that it will work with homebrew bundle install again? Thanks!

[brokenalarms]

actually, on my M3 Macbook Air I confirm that this beta still doesn't expose all the temperature sensors anyway.

(Realizing ofc that the Air doesn't have a fan, but I run MFC on both my Air and Pro for universality of my brewfile, and still make use of it in fanless devices for temperature readout).

[MysticalOS]

I don't see any fixes since last beta. still can't read the M3 sensors correctly. The message about fan control is a nice addition but shouldn't we have full sensor data by now? few of us sent it ages ago.

[kleuter]

@brokenalarms Please post tech info and app screenshot as described at here.

M3 max sensors are coming

[kleuter]

Build 66 should correctly display M3 Pro/Max sensors now

[MysticalOS]

Like your scree shot, it's missing efficiency core 3 and performance core 11 and 12, but otherwise much better.

[kleuter]

Build 67 addresses efficiency core 3.
Regarding missing performance core 11 and 12, please post tech info from build 67
Thanks

[kleuter]

MacBookPro20,6 has only 10 P-cores, MacBookPro20,7 has 12 P-cores

[MysticalOS]

Build 67 addresses efficiency core 3. Regarding missing performance core 11 and 12, please post tech info from build 67 Thanks

That'd produce something diff than #716 (comment) ? I'll repost soon

[MysticalOS]

MacBookPro20,7_tech_info.zip

Guess it is a little diff since it flags correct mac model now.

[kleuter]

Please check build 68
