- Thread-topic: New iMacs Monitors automaticlly de-calibrating
Hi all,
I'm struggling to turn off the ambient light sensor setting (via script) in the Photography labs I manage
Have been toying with the dAuto key in com.apple.BezelServices.plist preference, but doesn't seem to have any effect.
These iMacs are running the latest 10.6.8 (downgraded from Lion) and are model identifier iMac12,2
Has anyone else managed to tame this annoying 'upgrade'? :-)
I was thinking of doing something as drastic as removing the kext (if there is one) that controls the ambient light sensor…
Cheers,
Hamish.

Subject: New iMacs Monitors automaticlly de-calibrating
We have new 27 inch iMacs in our multi-user student labs with color managed monitors
The new iMacs (v12,5) however now has an ambient light sensor.
Users logging in for the first time on these iMac's always have the default for the new "Automatically adjust brightness (of monitor) as ambient light changes" check box ON, in the monitor control preferences. The problem this causes In our low-light level lab is that this auto feature then moves the brightness of the monitor down from our 120 cdm setting every time a new user logs on.
Our IT Tech is still trying to find a way to have the auto brightness off as a default for new users but has so far been unsuccessful.
Has anyone been able to solve this?
Note:
Students are given localized accounts on our iMacs that self erase after 8 day of non-use
