Hi,

I have been having difficulty activating my F11 and F12 keys on my Mac pro laptop. The operating system is OSX 10.6.8. This means I can't undo my renders.
I have gone into Blenders user preferences and set emulate numpad and continuous grab/and I am selecting with left click, however the function keys are not working right. Even when I hold down the function key and click F11 it still does not undo a render.

Any help will be apprecited.

I didn't find the right solution from the Internet.
