I have a MBP with an apple wireless keyboard. The keyboard has brightness keys on it but they have recently stopped working. It is strange as the keys on the MBP still work but the ones on the bluetooth keyboard, placed exactly in the same spot (the wireless KB and the Macbook pro's KB are exactly the same), don't.
When I wake my Mac up from sleep, and attempt to change the brightness using the function keys, I see the brightness "image" pop-up on the screen, but when I try to lower it, the brightness doesn't change. The boxes quickly go down, but instantly go right back up to the original brightness. Running Mac OS X 10.6.4
I have a 2011 (?) macbook air and ever since my trip to the genius bar for a battery issue my function keys don't work after I wake it up (just opening screen). May also be related to last firmware update?
I have checked the function key mapping in settings and they are normal. The volume key launches Expose and the brightness keys (and others) don't do anything. A reboot helps but only untill the first time I put it to sleep (close/open lid).
Really stumped by this. Recently (I think it was after a MacOS update but I'm not sure) my brightness and volume keys stopped working on my 2011 13" MacBook Air running MacOS 10.9.4. The F keys still work i.e. if I press Fn-F10, I get the expected effect from pressing F10, but if I just press F10, volume remains unchanged (should get muted). Mission Control, Launchpad, and media keys (rewind, play/pause, ff) all work.
Using Karabiner, I checked to make sure the keys generate correct events. They do. Pressing the brightness keys generates 0x3 and 0x2. Pressing the volume keys generates 0x7, 0x1, and 0x0, which are the expected key codes defined in ev_keymap.h, the header file for HID. I can also adjust volume and brightness using the sliders in the appropriate section of "System Preferences."
So volume and brightness itself can be changed. They keyboard keys themselves work and produce correct keycodes. But whatever operating system feature (HID?) that is supposed to read the keyboard input and translate it into commands to the display and sound drivers doesn't work.
I've tried all the obvious stuff (restart, safe mode, toggle the Function key option in System Preferences->Keyboard). I've reset SMC and PRAM. Nothing has worked so far.
The only other thing I can think of is that a while back (before this problem started occuring) I got annoyed by the power button in the top-right corner of the keyboard, which I would occasionally hit accidentally. I searched for a way to disable it, and I think I found something -- now it only does something if it's held for 2 seconds. A quick up-down strike does not do anything. Perhaps in tweaking some setting to achieve this behavior (I don't remember what I did), I screwed up something with the brightness/volume keys, but this screw up only became evident later.
A few minutes ago I noticed that my MBA's keyboard was not lighting up as it's supposed to. A little experimenting and I found the solution (you may kick yourself, this is so simple): The F5 key decreases keyboard brightness. The F6 key increases keyboard brightness. The icons on these two keys are the clue.
The issue is with the brightness keys and the brightness slider controls. It appears that after the 10.4 upgrade the main LCD on some PBs and iBooks stops working. In my case the attached screen lost the ability to adjust brightness, but my external 20" LCD is fine. It looks like two things have happened. The association between the keys (F1 and F2) and the code for controlling brightness somehow got disconnected and/or the "capability" of the mac to adjust the brightness of the attached LCD got lost in the upgrade. We've tried repair permissions, rebooting, new users to no avail.
I just purchased a new wired keyboard for imac and brightness and volume control keys not working . i have tried adjusting keyboard settings. I have software version 10.5.8. Do I need to upgrade software.
The brightness is turned all the way off on my MacBook pro and the only way to turn it back up is through system preferences. But I cant see it and everytime I push the brightness control keys it makes a beeping noise. And won't do work.
i can't change the brightness on my macbook pro. i tried the buttons on the keyboard, went to settings and tried to do it from there, didn't work. i have restarted my computer as well and that didn't make a difference.
I have recently put windows 7 professional on my aluminum macbook, installed all the drivers, and so forth. I hook up my macbook up to an external monitor, and use a logitech dinovo keyboard for a mac. However, when I am in windows 7, the function keys do not adjust volume, brightness, and any other of the functions.
Following on from my recent post regarding the new apple wired keyboard after very helpful feedback from people who responded to my post I decided to take the leap and purchase it! Good news is that I am really happy with it and am glad that I got it! Much nicer then old apple keyboard that I was using.
I also downloaded spark v. 2.1.1 which has enabled me to change the functions of Fkeys to enable to play, pause, etc... in itunes in accordance with the keyboard layout. However, there are two functions that I am having difficulty assigning which are the F1 and F2 keys which allow the decrease and increase of screen brightness. So that I can control my screen brightness using these keys.
When I push the brightness key on the keyboard, the appropriate image comes up on screen and goes to full brightness, but the actual brightness of the screen doesn't change and the lack of change is reflected correctly on the brightness slider in System Preferences.
I have a MacBook running OSX10.6. Someone else was using it the other day and now whenever I hit my Shift key, it changes the focus to either the task bar or the other open app(s). I have reset the keyboard settings in System Preferences, tried another keyboard and still have the same issue. I created a new user account and the Shift key functions properly in the new profile. where else to look to restore the normal behavior?
I have no idea what happened but somehow the function of some of the keys on the top row on my Macbook Pro keyboard changed. For instance the dashboard key does nothing while the F12 key now shows the dashboard, F11 shows the desktop while F9 does what F3 did before etc.
I'm certain no fluids were spilt on the keys.
After I restarted and tried to change them back to the default function in the system preferences window, nothing happened.
when i was on my laptop and i forgot to put it on charge so it went flat while i was watching a movie (not on the internet). I couldn't be bothered charging it so i just put it down and went to sleep. The next morning i turned it on and tried opening safari and it went extremely slow, i got the beach ball and when i clicked the apple on top left to try to force quit, after 2 seconds of clicking that froze. When i tried to force quit it from my dock i would click force quit and then my dock would freeze. At this point my mac was just about completely frozen. The brightness didn't change, sound nothing but only the mouse could move. I reset and the exact same thing happened. Google Chrome works so i am using this and i get no freezing problems. It is just when i use Safari.
The brightness goes up when you plug in your MBA, but then over time it just goes up and up. I honestly like my brightness pretty low (rarely more than half, typically at 3-5 notches), but it just keeps on going up and up. I almost never set it above half, but multiple times a day, I notice that it looks pretty high and it's at like 3/4 so I put it it down to about 1/3, but after a while, it's just up again.
Anyone else notice this? What is it, why does it do this? How can I fix it? I don't mind not having auto-brightness (even though I loved it), as long as my screen doesn't keep going up.
My wife has an iMac (I don't know any other way to identify it e.g. model number), and she has this 3rd party calibration software that I'm trying to use. I am not used to a Mac, and I cannot find the display settings for the monitor. There are no buttons on the monitor, and when I go to preferences, I can only find the brightness control. I've googled this and cannot find a clear, simple answer. I have used every version of Windows (currently on 8.1 on my PC) and it's easy for me on that platform. I suppose it's just that I don't really know how to navigate Mac OS.
This has stopped working for me. The volume and brightness keys have stopped working, regardless of what I set "Use all F1, F2, etc. keys as standard function key" to. I'd love to know how to restore the default function key behaviour.
I just installed Snow Leopard and the Modifier Key option no longer works. i.e. I can't switch the CTRL and COMMAND keys. The option dialog still pops up, but the keys don't actually switch. Does anyone else have this problem? Is there a work around or a preference file I can change manually?
