I know that if you want to check your depth on a PC, you press F3, but on my Mac, pressing F3 brings up Mission Control and/or the Dashboard.

Is there a way to check depth in OS X without manually counting blocks?

The debug screen is triggered when the F3 key is pressed (Fn+F3 on Macs and some laptops).

Debug screen, Minecraft Wiki


If you prefer to not always have to press fn when you press F3 then you can reverse the setting so that you press fn with a function key to perform the standard OS X task (i.e. Mission Control would be fn+F3).

System Preferences option

System Preferences > Keyboard > Use all F1, F2, etc. keys as standard function keys.


You need press the fn key and F3 simultaneously

If you press shift Fn and F3 it won't show the graph and pie chart.

You need to press fn + F3.

I have the same set up and got it to work today.

    You don't need the control key: just fn and F3.
