My Magic Keyboard with Numeric Keypad volume keys don't work properly.

Function keys can be "mapped" for different actions.

Go to System Preferences > Keyboard > confirm the checkbox next to "Use F1, F2, etc. keys as standard function keys" is checked.You can also eeeview settings under the Shortcuts tab.

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

Try a SMC reset. The article covers when this is required, but doing this will not affect anything.

Reset SMC

This does not solve the problem. Should the "Use F1, F2, etc. keys at standard function keys" be CHECKED or UN-CHECKED? Neither one of these has any effect on the volume keys (F10, F11, F12). I am running Capitan 10.11.6, BTW.

I have the same issue as well as I am missing the "Use F1, F2, etc." option running El Capitan 10.11.6.

Have tried resetting PRAM but that didn't help. Come on apple. Why is your product not working with your other product?

I have the same issue. Just received and set up my new apple keyboard with numeric keypad but the option in the keyboard system preferences to control the function keys does not exist - this option is not there:

Select "Use all F1, F2, etc. keys as standard function keys"

My iMac is not recognizing the Function Keys or the Function Key alternative uses.

VERY frustrating.

Unfortunately with the magic keyboard and numeric pad, we do not have the option to check or uncheck this box. I have spent hours messing around with every shortcut possible and regrettably there are no ways to fix this problem yet. Apply needs to figure out a solution and upgrade to where it allows us to either check or uncheck the box or add a way for us to add a shortcut to our keyboard where we can choose the F10, F11 and F12 keys to function for volume. I do have some tricks to make this less frustrating. Go into system preferences, keyboard, shortcuts, mission control. There you will see where the F11 and F12 keys are assigned. Double click on that and remove F11 and F12 and put in different options. I like the ability to show desktop and dashboard but I don't like it being on the volume keys because with my other magic keyboard without numeric pad the volume keys do work and I don't want to get use to using the volume keys for showing my desktop and dashboard. I changed them to F18 and F19. Much easier and it also frees up the volume keys just incase apple gets their crap together, actually reads our concerns and fixes this issue. I also recommend playing around with all of the tabs and correcting your key shortcuts. There are a lot of things you can use your keys for which makes things easier to access. F13 through F19 are all free and have nothing assigned to them so you can assign whatever you want to these keys. I personally added some screenshot shortcuts, notification shortcuts, image import, internet and sticky note shortcuts with those keys. So although we are out of luck on the volume, this makes things a little better at least for me. Now for the volume. At this time there isn't a way to control it on our keyboard which is frustrating, however I can make it at least a little more convenient. Go to system preferences, sound, and check show volume in menu bar at the very bottom of the window. This will add the volume control at the top right corner of your desktop. This makes it a little more convenient to control the volume. Hope I helped a little.

The volume keys work but you have to hold down the fn (function) key to the right of the delete button. Im running 10.13.2 on a 5 year old macbook pro. I have the checkbox checked for 'use function keys as standard function keys'. Now if the screen brightness keys worked...

I have 10.10.5 and using the function key doesn't work. I also don't have the option to select use the F1 keys as standard. However, I was able to use the shortcut remapping to get the brightness keys to work. Hope this helps.

I had this issue, and could not find the solution on this page. I went into System preferences, then keyboard and used both the boxes at the lower part of the popup i.e. "Change keyboard type" and "set up my keyboard" and it worked. I can now press the Function keys and increase/decrease volume without the dashboard appearing/disappearing! Wish I knew exactly what I did because the first time I "set up my keyboard" the keys were still acting strangely. Perhaps the trick was that I did both in sequence. Wish I could have been more exact and hope this helps.

Are you looking in the Keyboard tab?

Yes. See, I don't have have the option everyone is pointing to...

This keyboard requires macOS Sierra 10.12.4 or later, and iOS 10.3 or later — for proper Bluetooth functionality.

I don't even have that option. I am running the latest software too. There is no "Use F1, F2, etc. keys at standard function keys" in the keyboard preferences.

I'm having the same problem and there is no option to select F!, F2 box under preferences. Plus my keyboard is slightly bent out of the box. is that the way it is designed?

This is my problem as well. There are no step 1 or 2 options about the Function keys in my system preference. My iMac is not recognizing my keyboard as an Apple Keyboard
