10.10.3 caps lock and tab key problems

Since I upgraded to 10.10.3 I've had no tab key or caps lock. No one else has written about this. Am I the only one having these problems?

I guess I will take the keyboard home to try with a different Mac.

Hi venustas,


It sounds like you updated your computer and now 2 keys do not appear to be working. You should use this section of the following article to troubleshoot that:


OS X Yosemite: If keys on your keyboard don’t work


If other keys don’t work

You may have accidentally set an option that changes how your keyboard operates.

Choose Apple menu > System Preferences, click Dictation & Speech, then click Text to Speech. If “Speak selected text when the key is pressed” is selected, deselect it or click Change Key to select another key.

Choose Apple menu > System Preferences, click Accessibility, then click Keyboard. Make sure Slow Keys is turned off. If Slow Keys is on, you must hold down a key longer than usual before it’s recognized.

Choose Apple menu > System Preferences, click Accessibility, then click Mouse & Trackpad. Make sure Mouse Keys is off. If Mouse Keys is on, pressing keys in the numeric keypad moves the pointer instead of entering numbers.

Choose Apple menu > System Preferences, click Keyboard, then click Input Sources. Select “Show Input menu in menu bar.” Open the Input menu, then make sure the correct keyboard layout is selected.

To see the keyboard layout, click Keyboard, then choose “Show Keyboard & Character Viewers in menu bar.”



Thank you for using Apple Support Communities.

Thanks, Sterling. That didn't solve my problem, but it's good to eliminate possible causes.


It seems like the problem has expanded, which seems more like hardware than software. The Caps, Tab, cedilla, and escape keys don't work (shift still does) and now the hyphen / dash key has stopped working too.


Because my keyboard is still under warranty, it looks like Apple will send me a new one.

I'm having the same problem and am pretty sure it's a software issue. First I noticed the tab and caps lock keys weren't working on my wireless keyboard. The built-in KB on my MacBook Pro Retina OS X 10.9.5 seemed to function normally--until I tried the F10 key to increase volume. It switched screens instead. I just tried to check my OS version, and clicking About this Mac in the Apple menu brought up nothing. I've been through Apple Support articles, reset Bluetooth, checked Preferences, deleted suspect files from Library, etc. Nothing seems to work. I suspect something got changed when I installed a firmware update for a drone via Windows 7 (running on VMWare Fusion on my Mac), but I can't figure out what that could have done to affect the Mac OS side or how to set things right. Any ideas? Thanks. Michael

Keyboard/Mouse – Troubleshooting Wireless


Bluetooth devices become unresponsive


Bluetooth Interference Sources


Bluetooth Interference Sources (2)

If your Wi-Fi is capable of generating a 5 GHz signal, try that.


Restart the computer holding down the command - option/alt - P - R keys before the gray screen appears. Continue to hold until you hear the startup chime for the second time.


Reset NVRAM/PRAM

Thanks, Eric. I tried your PRAM reset several times, some of which produced multiple start-up bongs, but nothing changed. The problem now is clearly beyond the wireless keyboard. I can't control volume with F10-12 keys on MBP keyboard unless I hold down function key. Delete key on laptop okay but fn/delete on wireless KB doesn't switch from del/backspace. I did plug in a USB3 external drive a few days ago, the first time I have used a device with the new standard, but it hasn't been connected since then. I did not notice the keyboard problem until the next day. Any other thoughts?
