Tried just to boot ubuntu on MacBook Pro Retina (2015) and realised that 'Fn' key doesn't work. Can't change sound volume, display brightness, etc from keyboard. Is there a way to fix it? Hi, i'm very interest to install ubuntu on my mac book pro retina 15', i have some question before procede to the installation. Changing the way the FN key works. If this is just about changing the functionality of the FN key in Mac OS X, then the setting is under System Preferences -> Keyboard -> Use all F1, F2, etc. Keys as standard function keys checkbox.

Open Update Manager, go to More, then Advanced, click on Configure Software Sources; or open Software&Updates. Check 'Source Code' under Ubuntu Software. Under Other Software, check 'Canonical Partners' and 'Canonical Partners (Source Code)'. Under Updates, uncheck 'Check for updates' (if you are using Update Manager), change 'Automatically check for updates' to 'Never' and change 'When there are security updates' to 'Display immediately' (if you are using Software&Updates). Then, reboot your computer.

If your Apple keyboard has icons printed on some of the keys on its top row, these keys can be used to perform the special features shown in each icon. They can also be used as standard function keys (F1–F12). The action performed by standard function keys varies depending on the app you're using, or depending on the keyboard shortcuts listed in the Keyboard & Mouse pane of System Preferences:.
By default, pressing one of these keys performs the special feature indicated by the icon printed on the key. For example, pressing the keys with speaker icons adjusts the volume. If you want to use one of these keys as a standard function key, hold the Fn key (usually in the lower-left corner of the keyboard) while pressing the function key.
For example, pressing Fn-F10 (speaker icon) performs the function assigned to the F10 key instead of toggling mute on or off. If you prefer the top row of keys to always behave as standard function keys without holding the Fn key:. Choose System Preferences from the Apple menu. Click Keyboard. Click the Keyboard tab if it's not already highlighted. Select 'Use all F1, F2, etc.
Keys as standard function keys' With this option enabled, the keys on the top row act as standard function keys (F1–F12). To use a feature indicated by the icon printed on a key, hold Fn while pressing the key.
