Function keys with external keyboard
Solution 1
The only way is to disable system-wide (that includes the notebook's keyboard) the custom control keys, and tell OS X that you just want to use it as normal F1-F12/F16 keys.
Go to System Preferences > Keyboard. Check the box that says "Use all F1, F2, etc. keys as standard function keys"
If you are using a Mac keyboard, there should be a Fn key. On the latest Mac wired slim aluminium keyboard, it is around the home, page up, page down area. On the wireless slim keyboard, it is to the bottom left.
Solution 2
Silly me. The fn
button is below F13
.
Solution 3
You can do that with Karabiner-Elements:
It allows you to configure the Fn keys per device. In this case, I set it to use the default keys when on the external keyboard:
Solution 4
If you're using an external keyboard for a mac, check the external keyboard for a f-key lock button. On my logitech it is on the escape key.
(I just spent half an hour figuring it out!)
Solution 5
Interestingly for me Scroll lock (F14) worked as brightness down and Pause Break (F15) as brightness up on a USB PC keyboard.

When using an external keyboard, how can use a function key as a function key (e.g. F10) instead of Mac custom control button (e.g. mute)? The built-in keyboard contains an
fn
button, but I cannot find it in the external one. -

chrismarx over 7 yearsI am happy to report that you can safely enable this on the new 2016 macbook pros, and it works just fine for an external keyboard and leaves the touchbar intact!

choise about 6 yearsThanks, that totally worked for me using a windows keyboard on the mac. Not only i now can use the function keys for media controls as default osx does, but i also remapped all special keys like CTRL/ALT/WINDOWS key to match the layout of a mac keyboard. Great! Note: If you also use a "windows" mouse and need different scrolling directions for the mouse and your trackpad, check out "Scroll Reverser"

Guillermo Garcia over 4 yearsI use Spark and it helped me to remap some shortcuts in my Windows PC Keyboard to control some basic functions like the volume commands. A Con, the app was not maintained in a long period of time. Latest version 3.1b2 (470) can be found at shadowlab.org
