Can't remap caps lock in system preferences anymore

I just discovered that when I go into system preferences to set up a new keyboard under Yosemite 10.3, and click on "Modifier Keys..." to remap the modifier keys, the only valid mapping for Caps Lock is now "No Action." "Control," "option" and "command" are all greyed out. What gives? Do I have to buy a $200 happy hacking keyboard now to have Control to the left of 'a'?

Look at the headphone port to see if there's a small red light inside. Doing this in a darkened room might help. If you see the light, try inserting and removing a headphone jack a few times. Sometimes the port gets stuck on optical. If the headphone jack trick doesn't work, insert a plastic toothpick or maybe one prong of a plastic fork and gently jiggle it around. Don't use too much force, since you don't want to break that off inside.

Can't choose speaker output in system preferences anymore.

Hi,
Can't choose speaker output in system preferences anymore. The only option is optical digital output. Any suggestions?
Thanks

Remap caps lock to Ctrl in console (tty)

I tried to use loadkeys to remap caps lock to Ctrl and Ctrl to caps lock but it doesn't work, because i think use caps lock is easier than press Ctrl when i move around keyboard. so i wonder:
1. how can i remap caps lock to Ctrl and Ctrl to caps lock in bash (in tty)
2. how can i remap caps lock to ESC in vim (in tty)
I tried to modify /usr/local/share/kbd/keymaps/personal.map
keycode 58 = 29
keycode 29 = 58
58 is caps lock keycode
29 is control keycode.
Thanks in advanced!

yep, tks a lot, english is not my native language.
write a super short script that simply changes keymap before calling vim.
you mean i need to reload keymap when i call vim. if that i need to modify my .vimrc to call a script to reload the keymap. humm, that's problem, how can i call a script in .vimrc? i am new to linux so can you show me howto?

Can't load Network Settings from System Preferences

For some reason I can't load Network Settings from System Preferences anymore - it just stalls with the bar showing "Loading Network" and doing nothing. This is happening in conjunction with a new inability to connect to a network printer - it won't show up on the list of printers, even when I manually enter the IP address. Something is obviously mucked up - can anyone tell me what it might be & how I can fix it? Thanks!

I was able to fix this myself by using one of the techniques suggested here for a different problem. Basically I went into Library/Preferences/System Configuration and deleted networkinterfaces.plist, preferences.plist & com.apple.nat.plist. All were rebuilt when I restarted and went to System Preferences/Network and I was able to load the Network Settings. This didn't fix the problem with my printer, but at least it got the settings up.

Remapping caps lock to a sticky fn key?

The new layout of the f-keys along the top of apple keyboards is annoying at best, particularly for those of us who use the f-keys as function keys (because they do marvelous things in certain applications, like Eclipse).
Most of the time, I'd like the f-keys to be f-keys (i.e. F12 is F12, NOT increase volume), but I do use the special hotkeys (iTunes control, volume control). The trouble is that my hand is not large enough to change the volume with one hand (I could with my old powerbook, because volume control was on the left, not on the right!).
The best solution, for me, would be to remap the caps lock key to be a sticky fn key (which toggles the F-keys between F-key and hotkey functionality), that way, when I want to change the volume, I can hit caps lock, and then hit the volume keys until things are at the right level, then toggle back with caps lock again.
This would make the caps lock into a toggle for the f-key functionality.
I know I found a hint a long time ago about remapping caps lock to be a sticky language key...which I used to use...but I think that's specific to the language system.
I've also check out DoubleCommand (doesn't do this), and uControl / fKeys (but neither are supported anymore and require legacy systems).
Anyone out there have a solution?
-Zach

Just to be clear, part of the problem is that I do use the hotkey functionality SOMETIMES, but that requires the combination of the fn key (in the lower left-hand spot on the MacBook) + the desired f-key. My hand doesn't reach from the lower left-hand corner of the keyboard to (very nearly) the upper-right hand.

Shift-Caps Lock-Tab not working with remapped Caps Lock

I've remapped my Caps Lock key to Ctrl using the Preferences > Keyboard > Modifier keys dialog and in the following question when I say CTRL i mean the Caps Lock key remapped to Ctrl and Ctrl is the normal left Ctrl key.
I'm using OS X 10.9.4 and I've just bought 2 new external corded Apple keyboards and both of them are having trouble with the key combination Left Shift + CTRL + Tab. For applications where that combination should go to the previous TAB it does not work. If I use the right Shift instead it works fine, if I use the left Ctrl key instead of the remapped Caps Lock key it works great too.
The internal keyboard on the laptop works fine with Left Shift - Caps Lock - Tab.
The computers are a Macbook Air 11" Mid 2011 and a Macbook Pro 15" Mid 2010.

Hey,
Sorry to hear about the keyboard problem.
In a post a while back had this to say. He makes a suggestion that the keyboard might need to be replaced, then the person with the question tried something else. You might take a look and see if there's something there that will help.
Thanks for coming to the forum.
Hope I helped,

Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.

Do you have 2-step verification on for your Apple ID? I may have a solution.
When I upgraded to Yosemite and subsequently updated my Apple ID, I would get errors when I tried to sign into iMessage and FaceTime using my apple ID (and my new password), I similarly was not able to sign in. On FaceTime, I would get errors like "unable to sign in at this time" or some times just nothing at all (the spinning 'processing' graphic would grind away until it presumably just timed out).
Turns out that I enabled 2-step notification on for my Apple ID (totally forgot about it, I set it up a couple years ago), and apparently the regular Apple ID password that you choose is not usable when you try to log in to iMessage or FaceTime through the programs themselves (intuitively, this makes sense since these programs do not have a way to prompt you for the "2nd step" code).
To solve, you have to log in to your Apple ID online (appleid.apple.com or whatever), and look for the option to "Generate App-Specific Passwords". These are unique, random passwords which are made to work around issues like these since they can be used in iMessage or FaceTime or what not. This is the same idea as to what you have to do to log into gmail on your iPhone if you have Google 2-step verification on.
This solved my issue (after lots of swearing and hair pulling!). Would have been nice if a I got some sort of warning when updating my Apple ID password that "Hey, you have 2-step enabled. Go make some app-specific passwords or you will lose 5 hours of your life trying to solve this mystery"
Hopefully this may solve yours

Can't change Desktop background in System Preferences

Hi. When I try to change my desktop background, either by right-clicking on the desktop or by opening System Preferences, the screen for Desktop options is blank. None of the options show up, grayed out or otherwise. While in System Preferences, if I click on Screen Saver, everything there works fine. But the button for Desktop becomes grey and I can't click on it.
I've tried Repair Permissions and this didn't work. I've seen similar posts here, but they don't seem to have the same problem I do, nothing freezes up, the Desktop screen is just blank. Do you have any ideas?
Thanks!
Mac OS X (10.4.6)

1. OK, let's try some more trashing: 1. Quit System Preferences if it is open.
2. Open your Home > Library > Caches folder, then trash the following two files therein:
- com.apple.preferencepanes.cache
- com.apple.preferencepanes.searchindexcache
3. Trash the file
com.apple.systempreferences.plist
in your Home > Library > Preferences folder.
4. Trash the file
com.apple.systempreferences.xxx.plist
in your Home > Library > Preferences > ByHost folder, where xxx is an alphanumeric string.
5. Empty Trash.
6. Launch System Preferences and see if the problem is resolved.2. You wrote"I still have my Desktop Pictures folder."I presume you mean the Macintosh HD > Library > Desktop Pictures folder I cited previously. How about the contents of that folder? It should contain five folders:• Abstract
• Black & White
• Nature
• Plants
• Solid Colorsand a collection of .jpg images for a total of 28 objects.
3. I know you earlier said you ran Repair Permissions. I presume the permissions on Macintosh HD > Library > Desktop Pictures are:You can: Read & Write
Owner: system
Access: Read & Write
Group: admin
Access: Read & Write
Others: Read OnlyYes?
4. If none of the above sorts it out, let's see if it's isolated to your account. Do you have a second user account defined on your system? If so, log in to it and see if the problem happens there. If it does, it is probably a system-wide problem. If not, it is something with your user account. If you don't have a second account on your system, you can create a new one using System Preferences > Accounts. See "Mac OS X 10.4 Help: Adding a new user account to your computer."
5. Immediately after the problem occurs — i.e. you open Desktop & Screen Saver preferences and either cannot select Desktop or Desktop is blank — check the ends of these Console logs for clues. Let's see if console can tell us if the Desktop preference pane is corrupted.
6. Do you have any personal Web space? If so, can you take a screen shot of the problem and upload it to your personal Web space? If so, post a link back here to the image. It may help if I can see what you're seeing, though I think I understand it from your description, "a picture is worth..." etc.
7. As a general check, run the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
8. To what was / is your Desktop image presently set? One of the Apple collections or images? Something from your iPhoto Library?
FYI: I number my points so you can respond by number.
Good luck!

Can't access Users & Groups in System Preferences :(

I can't access Users & Groups in System Preferences please help thanks

Check the following:
First, do you see the "User and Group" icon?
If not, open the "presentation" menu and look under the "personalize" option to see if the icon is uncheck.
Second, try to set a new account and see if you can access it from that account.
Repair disk permission

System Preferences quits suddenly. I have lost the dock, including the trash and ability to change desktop image. How can I replace this part of System Preferences? Where can I find Trash?

System Preferences quits suddenly. I have lost the dock, including the trash and ability to change desktop image. How can I replace this part of System Preferences? Where can I find Trash? All other aspects of System Preferences work.

just that that is one method, and lacks provision for working boot image and for an emergency - Lion gives a small minimal emergency boot environment but may lack all the utilities you need to use and run, even some drivers that your mac requires for add on PCIe.
Just grab and look through Help in Carbon Copy and SuperDuper, both excellent and each has their use - together - for cloning.
And do you have two TM backup sets? ought to consider that also, rotate daily or make a weekly set. Otherwise you are putting all your eggs in the proverbial one basket.

Security PreferencePane Lock in System Preferences

For some strange reason the lock in the left hand bottom of security Preferences does not stay locked. Every time I reboot it is unlocked. Is there a fix for this.

With some exceptions (eg. the "Accounts" pref pane), it is standard behaviour for "secure" pref panes to be unlocked when logging in the an "admin" account, although this can be changed via "System Preferences" > "Security" as described in this "Help" document:
http://docs.info.apple.com/article.html?path=Mac/10.5/en/8675.html
The presumption is that users log in to "admin" accounts in order to administer the computer so the default behaviour is a convenience feature. However, especially in light of some outstanding security issues, it is recommended that users do not log in to an "admin" account routinely.
Unfortunately, the benefits of using a non-admin account are currently mitigated due to the recent release of a reported "standard" -> "root" privilege escalation vulnerability...

Can't unlock startup disk in system preferences

I installed Tiger and the startup disk on system preferences is locked so I can't boot into OS9. When I type in my name and password, I get a message saying "type in user name and password." I can log into OSX OK at startup with the same name and password. There are no other users of this computer.
Any ideas?

Hi, Dark-Sabre -
Apple KBase Article HT2176 sets out the requirements for OSX 10.3 (and gives links to articles showing the requirements for later versions of OSX). Included is the need for the machine to have at least 128MB of RAM. Doubling that amount is a more realistic minimum.
As Grant has suggested, be sure the firmware has been updated on the machine. On many model iMacs, early ones in particular, the machine may suffer loss of video if the machine is booted to OSX prior to updating the firmware.

[SOLVED] KDE: Remap Caps Lock

Hi,
I've mapped the Caps Lock key as keyboard layout switch; it works, but somehow I can't disable the Caps Lock function (I've got English in all caps, unless I lower them with Shift-Caps Lock). I suppose I should check some option in Keyboard Settings->Advanced->Caps Lock Key Behavior, but I can't find the right one.

I'd like to achieve what I once had, even with KDE : CapsLock toggles the keyboard layout, Shift-CapsLock works as a substitute for Caps Lock.
The first part I've got, but not the second one.
