How to use F1-F12 keys with MacBook? Blender requires F-keys such as F12 and numpad. The numpad emulation works for me, but I am unable to get the function keys such as F1, F4 and F12 working. For example, F12 should do rendering. So how can I use Blender with a MacBook?
You have two options; either hold down fn as L2G suggested, or switch to the F1 etc. keys to work like that directly.

This can be setup in keyboard preferences here:



If you do that, F1 will work as the actual F1 key. If you want to use it for controlling the brightness, you'd hit fn with it.
