OS X :: Function Keys Not Working / Sound System Preferences Grayed Out
Apr 14, 2009
I just bought a 2.4 MBP model a1260. When I got home i noticed the volume keys were not working, and then i noticed none of the function keys were working properly. (example, f12 shows an eject CD symbol). So, the keys are working but not doing the standard functions such as volume and brightness.
I have check and unchecked (and restarted) the "use all f1, f2 as standard function keys" to no result.
Some other wierd things that seem to be related are:
1. In the SOUND window in SYS PREFS all sound effects are greyed out. Under OUTPUT and INPUT it says no devices found.
2. When i go to the itunes store in itunes and i double click on a song, it wont play. Not only is there no volume, but song wont play. Its the same with my own music from my cds.
3. When i insert a DVD no volume control shows up.
And the last superwierd thing (haha) is that I reloaded leopard and when the computer restarted up after install there was no OSX music that normally plays as the video flys thru the starfield.
Headphones have no audio either.Sorry so long. The computer has no warranty of course.

so heres what happend. my macbook has been acting strange. freezing and sound not working at times. system preferemces quitting etc. and i just got it back from its thrid repair. THREE REPAIRS IN LESS THAN 3 MONTHS> so i was downloading a game for my psp when i went to go get a bagel in the kitchen. i left for no less than a minute and when i came back the screen was black. i thought it just dimmed itself but no. i moved the trackpad clicked on all buttons click the mouse button everything. i noticed the light wasnt throbbing so im sure it wasnt sleeping. the light was just pure white(the sleep light) so i waited like 3 minutes than shut it down. do u know whats happening. i know now i will be getting it replaced but until then im trying to keep it working well enough that i can watch a ********** vid on youtube.
I have a Mac os x with the Windows vista partition. I downloaded Realplayer to view some videos on both the windows and mac side. When I did the latter I realized that this was the problem; all my function keys stopped working, I cannot control volume, eject, brightness, anything. I have uninstalled Realplayer from the Windows partition and the problem persists. I have tried to look into the systems folder and drivers, but I really don't know what I am doing and I don't want to make it worse.
I just bought a new wireless keyboard to use with my iMac. My function keys at the top of the keyboard are not working and when I try and fix them in system preferences, I am unable to. There is no option to get the rewind, play/pause, fastforward, mute, volume down or volume up to work.
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.
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 just installed Windows 7 on my Windows partition and everything works fine (video, audio, etc.) except when I try to control the sound from my keyboard with F10, F11 and F12....nothing happens.
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 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).
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've got a new 15" mbp that tonight I drove out with to the apple store. It was unable to mount external devices (iPods, external hd's, etc). The Genius ended up doing an archive install, saying that the mounting disks were running full throttle (making it EXTREMELY hot) but not succeeding; something in the OS had gotten stuck. So I left after he did an archive and install and tested my drive and iPod. Everything was working....I thought. Long drive back home. Open up my computer, try to adjust screen brightness...nothing. Try to adjust volume. Nothing. None of the function keys work. The eject button works, and strangely enough, the F12 button which should raise the volume also tries to eject. The pause button brings up the spaces window (showing all four spaces).
Very frustrated, could use some advice. Do I need to do an erase and install? These keys worked fine before the archive/install.
I cannot control my screen brightness using the F5 and F8 keys. The only way I can adjust it is through System Preferences. I tried just F5 fn F5, Control F5, Option F5 and Command F5 and non work.
I know how in keyboard preferences to mark the check box that says "Use function keys as standard function keys," but my question is, is there a way to use a hot key to make this swap instead of having to open up system preferences, navigate to the proper pane and tab, and click the box? I have a couple programs where I absolutely need function keys to be function keys, but for general purpose use, I need the function keys to be the spiffy stuff printed on them.
Ideally I'd love for the system to look at what app was in the foreground (that is, has control of the menu bar) and recognize this app as needing access to function-function keys and make the swap for me, but I don't think this is possible at the moment, and having a hot key to change it would be the next best thing.
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?
Yesterday I use my headphones to listen music from my mac. Today after I turn on my notebook I saw that my sound icon is grey and when I try to change the level of the sound nothing happens. When I put again my headphones the sound works.
I also saw that I have no option to choose Internal Speakers in Sound menu.
Whenever I assign shortcut keys to Spaces using the Expose' & Spaces panel in System Preferences, it seems that in a day or two the shortcut keys no longer work and System Preferences shows them as being unassigned. I thought there may be a conflict with another shortcut but there isn't - at least according to the Keyboard & Mouse panel in System Preferences. This happens on both my MBP and my iMac as well as on the PowerMac I recently sold. I've tried other keys and combinations but with the same results. I've also experienced this in all versions of Leopard including the current 10.5.7. I'm using F8 to activate Spaces, Command + Option + Arrow key to switch between Spaces and Command + Option + Number key to switch directly to a Space. Has anyone else experienced this?
My 2008 Mac Pro recently stopped producing any sound.
The startup chime is silent. No sound comes from the speakers at all and the line out/in options in system sound preferences are missing, although it still lists my Logitech webcam microphone and the volume meter for it responds to sound changes.
Could the sound chip on the logic board have stopped working?
Could it be a virus or a software conflict? I haven't updated the system recently or installed new software, but Skype has been acting erratically and has crashed a few times.
The missing line in/out devices in the sound preferences seems like it might be a hardware problem.
I have tried all of the normal things like checking cables and resetting pram but no change.
I have the same condition whether I boot into my primary drive or into the clone (made before the sound stopped working) on a separate drive or into Windows through Bootcamp.
If the logic board integrated sound is broken, can I add a sound card to take over the audio for everything (startup chime, audio from software and audiovisual sources, Skype, etc.)?
When I try to change the keyboard system preferences or the bluetooth system preferences, the 'application' locks up (Doesn't bring up any details, force quit gets out of it). I've tried leaving it for ages to see if it eventually opens but it doesn't.
This means I can't use any bluetooth devices or change the keyboard shortcuts.
It only happens on one of my otherwise identical Mac Pros; the other is fine.
Any clues as to how to repair it? I tried reinstalling Snow Leopard but that didn't help. I didn't do a clean install though as I'd rather put up with it than make a clean install work with all the apps etc.
I accidentally (somehow) put system preferences in the trashcan and now it doesn't work. I've checked google, but I'm using OS Snow Leopard 10.6.3 and can't find anywhere how to fix it on this OS, anyone have a fix?
I tried the applications disk that comes with the computer as well, but no luck.
I watched a video and it was very loud so I went to System Preferences and turned the sound down.But now I can't mute by clicking the F9 button as I normally can. I can mute by going to System Preferences but I don't want to do this.Before I changed the volume in System Preferences, the keyboard keys worked fine for volume adjustment. I could make it quieter, louder or mute.I have tried with checking and not checking the option to display volume on the screen (in System Preferences).
