BFCL value does not seem to be restored on reboot

[godly-devotion]

Even after setting the bclm utility to launch at login, it doesn't seem to be restoring the BFCL property correctly. The MagSafe charger light is orange and it requires re running the utility to update it again. The BCLM property seems to be fine but that could be because it doesn't reset that value at reboot as easily, which could mean that its not running the command correctly at login.

Can you verify that /Library/LaunchDaemons/com.zackelia.bclm.plist has something like this section:

<string>/usr/local/bin/bclm</string>
<string>write</string>
<string>77</string>

And also that the bclm binary referenced there is at least version 0.0.3?

The LaunchDaemon plist file seems to be correct. For testing purposes, I modified the value from 65 to 60 to see if it would apply the value correctly. However upon logging in again, i checked the BCLM value and it was still set to 65 meaning the value wasn't restored correctly. I've updated the issue title to accurately reflect the problem I am having.

~ % which bclm
/usr/local/bin/bclm

bclm version is 0.0.4.

It sounds like possibly the job is not running on boot? Try sudo launchctl list | grep com.zackelia.bclm.plist and if it is working, it should have a status of 0 indicating it was successful.

[godly-devotion]

- 0 com.zackelia.bclm.plist so it seems it should've been successful.

Was able to replicate this, going to try and work on a fix here soon.

Still taking a look at this when I can... it appears that the BCLM value is fine but BFCL is getting overwritten some time shortly after the launchd job goes. So far I tried adding a niceness value but that didn't change much, still investigating.

Also facing this issue on MacBook Pro 15' Late 2013 running macOS Big Sur 11.1
Running the utility again fixes the BFCL value.

+1, just writing the keys to smc manually, I find that BCLM survives reboots but BFCL does not. I wonder if we can find which process is responsible for resetting this BFCL value.
