macOS: How do I stop iTunes from reacting to media keys?
On OS X/macOS you can remote control iTunes via the so-called media keys or controls. I.e.
Unfortunately, by default those keys start iTunes, which may or may not be what you want. To prevent iTunes from starting, you need to make sure the
rcd (remote control daemon—yep, that's the thing that reacts to your Apple remote) does not start or is stopped.
To achieve this, you need to start the
Terminal app (usually under
/Applications/Utilities, but if you cannot find it, just type
Terminal into Spotlight). At the prompt, enter the following two lines exactly as they appear here:
launchctl unload -w /System/Library/LaunchAgents/com.apple.rcd.plist launchctl stop com.apple.rcd
The first line makes sure that
rcd isn't started. The second line stops it, in case it is already started.
rcd, use the following two lines:
launchctl load -w /System/Library/LaunchAgents/com.apple.rcd.plist launchctl start com.apple.rcd
