MacBook :: Brightness Changes Rejected Using Function Keys
Aug 21, 2010
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).
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.
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.
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.
I recently upgraded to Snow Leopard on my Macbook Pro (early 2008) and now my function keys are mixed up. My volume keys are now F3 and F4 for example.
I have already unchecked, �Use all F1, F2, etc. keys as standard function keys� as standard function keys� in System Preferences and it didn�t fix the problem. Also, under the keyboard shortcuts tab I have clicked the �Restore Defaults� button. This also didn�t fix my problem.
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.
Today I received a bluetooth Razr mouse in the mail today and went to connect the device as I would any other. Well when I was playing music in iTunes, the function keys to skip, pause, and every other function key does not work. The volume keys move my windows and pull up widgets. I dont know if the mouse has anything to do with it, but I imagine it doesn't because I disconnected it and the problem remains.
I bought a new MacBook Pro i5 yesterday to replace my MBP LED (2.2Ghz). The function keys on the new MBP kinda suck. I really want the one that does "Show Desktop". If you go to keyboard layout, it says that F11, F12, etc., are assigned, but seems it completely ignores them. What the F? Even if I could change the expose button to show desktop, I'd be very happy. I know you can use the 4 finger swipe, but that doesn't help while trying to drag something from the desktop into mail.
The volume and other function keys aren't working as they used to. The brightness key doesn't do anything and the volume key isn't working either. I've tried to fix it on system preferences but it didn't work. They're not set to be used like normal function keys. I don't know what is happening they were working fine.
I was listening to music one day and went to pause the music using the Play/Pause (F8) key. I pressed the key and nothing happened. The forward skip and back skip keys also do not work with iTunes or any other program. I've tried resetting the key settings and restoring my Macbook Pro to a time when i remembered them working.
Info: MacBook Pro (13-inch Mid 2012), OS X Mavericks (10.9.1)
The top row of keys on my keyboard are not working i.e. sound buttons do not adjust sound, same with brightness etc. They make a sound when pushed but the functions arent working. I have booted in safe mode and reset sound cache, I have check all settings in the keyboard section of system preferences.
I have the original model, MacBookPro1,1. I want to change my keyboard backlight keys, or F11/F12, to control iTunes. Is there any easy/free/clean way to do this? no for-pay apps, as it isn't worth money to me.
Just recently the music control keys (the function keys 7-9) aren't working, all the other function keys work. The music control keys do not work even if I am in iTunes or if I set it to use function keys as standard function keys then try to fn use it. I just updated to Yosemite on Tuesday, I have turned my computer off twice since then and I restarted it today. I have a Macbook pro with retina.
Info: MacBook Pro with Retina display, OS X Yosemite (10.10.1)
I commonly work with remote desktops (using Citrix) on Windows servers from my MacBook Pro. The apps I commonly use require the use of Function keys. I know I can go into System Preferences to change how they work (turning the Fn option on or off), but this is difficult to do with the frequency I need to. When I'm not remoted in, I prefer to keep my keys as the normal Mac functions. Is there a utility for my Menu Bar that will let me quickly toggle this option, without needing to go into System Preferences each time? I looked up FunctionFlip, but it does individual keys, and no longer has a Menu Bar icon.
It appears that the function keys to control iTunes/Quicktime (FF, Play/Pause, and RW) are not working. At one point they did but now it doesn't. All the other function keys are functioning just fine and dandy. I have the "Use F1, F2, etc. keys as standard function keys" unchecked in the preferences. I looked around and there doesn't seem to be any setting that would explain the sudden malfunctioning of the keys. Is there something I may have missed?
I'm switching from a PC to a Mac. I have a PC utility called "My Function Keys" that allows me to "program" the function keys to do a combination of keystrokes. For example, I can set up F9 to do a copy and F10 to do a paste, so I don't have to do the Ctrl-C and Ctrl-V, or I can set up F2 to type my address, etc. Is there a similar utility for the Mac? I did find some information at this link: [URL]. Which states: iBook: How Programmable Function Keys Work. This article describes the programmable function key operation for iBook and the PowerBook (FireWire) computers. The programmable function keys were created to help simplify common, everyday tasks performed on the computer.
You can use these keys to open a browser, an email application, or any other frequently used application or server by pressing a single key. To set up a programmable function key, open the Keyboard control panel. Or, if the keys have not been programmed yet, simply pressing one of them brings up a dialog box that leads you to the Keyboard control panel. Apple has preprogrammed F1 through F6 with such common control functions as screen brightness, speaker volume, and so on. F7 through F12 can be programmed for your personal choices. To help you identify what the function keys were programmed to do, Apple includes with iBook a variety of durable stickers with preselected icons. Once the keys are programmed, you can select the stickers that will best remind you of the assigned functions.
Note: The stickers should not be placed on the keycap itself, rather above them on the iBook case. To remove the sticker, use a fingernail or other non-abrasive tool to remove them and avoid scratching the plastics. The function keys F1 through F12 can be easily reset to have primary functionality. Simply open the Keyboard control panel and select Options. Then check the box that says Use F1 through F12 as Function keys. Note: Programmable function keys are not a feature of Mac OS X 10.0. So, it appears the iBook will do what I'm looking for, but not the iMac!
