  1. Is the project abandonware? (If author hasn't got time for it anymore, that's only fair, and it would be good to go open and public with this, if so.)
  2. Is there anyone else with low-level macOS programming knowledge who could commit changes or take over the project?
  3. Is there a fork that's regularly updated?
  4. Are there other good simple, open source fan control apps or APIs?

Well, as long as reading and writing from the command line works, one can always create simple Bash scripts for whatever needs one might have. (Thanks to @Dirk- this now works again.)

PS! I also noticed that it's possible to raise the fan speed over the Max (6500 in my case for a Macbook Air 2017). Evidently, Apple has no mechanism for preventing this, and I assume this is all on your own responsibility. Would be nice to know if anyone has any information on the risks involved and if there is some threshold you should really, really not go beyond.

Hmm, the max fan rpm issue is interesting. Can you confirm (audibly or thru some other means) that the fan is actually running faster? I find it hard to believe that there isn't a built in hard limit in the SMC which makes it ignore erroneous fan speeds.

As far as I understand F0Mx=6500 is is the maximum speed (shipped with the machine). When setting 7000 or 8000 using smc -k F0Tg -w (with my fingers crossed and eyes closed), I could hear without a doubt that the fan speed increased drastically, but with no noise that would indicate that the fan starts to come in contact with its encasing or anything. Albeit my adventurous personality traits, I could not muster the courage to try values approaching 16383, which I obviously assume to be the maximum possible setting for these values.

@forthrin I just found an open-source app which lets you control the fan speed on M1. There are many other features in the app as well.

@SufianBabri: If it can control the fan on fanless machines, it must be really good!

SufianBabri commented 1 year ago

@forthrin maybe some M1 machine's don't have fans but mine does have. https://www.pctechkits.com/does-the-macbook-pro-m1-have-a-fan/

Yes, it appears to be abandonware.
