High Sierra version 10.13.4 does not retain monitor brightness after a restart. This is critical for photography. Has anyone been confronted with this issue and can it be fixed?
iMac Pro, macOS High Sierra (10.13.4)
10.13.6 finally fixes this issue! Or rather, the firmware update that's bundled with the software update fixes the issue. I guess they did not have time to finalize the new boot rom for iMac pro before 10.13.5 rolled out. Take a look at your Boot Rom version. It's now 15.16.6059.0.0,0.
By the way, I just ran the delta update, not the combo update, which is not out yet.
Cheers,
I updated it to 10.13.5 today and the problem still exists. Not sure what to do.
This latest update seems like it was all for security fixes, so not all that surprising that it wasn't addressed yet.
Mind tell us how you can get the "Delta" update. I just checked by iMac for updates and there are non listed.
BTW I have a late 2013 iMac 21.5 with the same issues.
Is this the 10.13.6 via the app update or some other way?
Not showing here in Southwest Washington State.
It's not unusual. It takes a while for the updates to replicate across multiple update servers. I am sure it will be all good in a couple of hours.
Not much you can do. If you already have a ticket with apple about this, update and let them know that the problem is still not fixed. I am starting to think they can't fix it. It looks like they had botched something badly in iMac firmware update when 10.13.4 was rolled out. And now they either don't have the resources to fix the problem, or they have not figured out how to do it. Or, they simply don't care.
Here is my solution, as the reset of the NVRAM/PRAM/SMC -- all have failed ---
and all other methods seem to be useless.
I have recorded an applescript that lowers the brightness to my desired level:
https://apple.stackexchange.com/questions/34884/how-can-i-dim-the-screen-from-te rminal
and basically its this command repeated 4x Times in the same file, that is executed as a login item:
[as after a reboot it goes to 80% which is far too bright for me]
Dimmer:
tell application "System Events" key code 107 end tellIf I could put {my} app here, I would, but... so you can lauch Script Editor, and put in the above, and then repeat until it gets to your desired level, then save it as an App, and then place it in the Login Items for your user....
Great post, and yes, I can confirm it works, having just tried it myself.
I have yanked my AppleScript that runs at Login, and it does keep the {same} brightness level on my iMac Pro now...
