Hey folks!

What's up with my Mac?

- Something reduces the screen brightness automatically. Recently the brightness was at half, without that i've done anything.

What's my problem?

- I don't want that!

What's curious?

- 'Automatically adjust brightness' is already deactivated!

..

What's the solution ?

Would be really glad for nice people who can help me :/

Perhaps it's an Energy Saver setting that's causing it.

System Preferences>Energy Saver - is 'Automatically reduce brightness before display goes to sleep' ticked?

Thanks for trying to help me!

Unfortunately, this can't be the cause, because the option is already deactivated too.

I clicked now additionally on the lock, so nothing can change the settings. Maybe it works now.. (?)
