In Maverick, whenever I double-click a track to rename it, iTunes launches and the track plays in iTunes. Very annoying. How do I disable (or re-assign) the double-click to launch/play in iTunes command? Thanks in advance.
I suspect you are clicking too fast.
A 'Double-click' in Finder opens the file or launches the application, etc.
On the other hand, selecting a file/directory, waiting a short period, then clicking again, will allow you to rename it. It's not technically a 'Double-Click' even though you are clicking twice (you could equally use arrows to navigate to the file, then click, for example).
You can alter that delay in System Preferences under the Mouse preference pane. The 'Double-Click speed' slider lets you adjust this. Perhaps you should move the slider closer to the 'Fast' end, which will reduce the chance of it assuming you meant to open the file instead of renaming it when clicking twice.
You can prevent iTunes from opening when you double-click on a track by telling the Finder to open some other Application when you double-click on an mp3, or whatever, music file. A simple Applescript such as
will do the job. Just open Applescript Editor, type the above script, and save it as an Application, e.g. "Beep.app". Then do a get-info on a music file, and set the "Open with" option to "Beep.app" instead of iTunes. Now try double-clicking on the track. You should see an expanding icon, like the file is opening, but nothing further will happen because "Beep.app" doesn't actually do anything with mp3 files. (Activity Monitor shows Beep actually opens for a few seconds, but it takes up no cpu, and the script itself doesn't execute.) Once satisfied that the script is working properly, you can go back to your mp3 file's get-info window, and click the "Change All" button to open any double-clicked mp3 with Beep.app instead of iTunes. That'll stop iTunes from annoying you when you're just trying to change a file's name.
click the "Change all" button to use the "Beep.app" to open all mp3 files
If you don't want the beep, you could even make the AppleScript do nothing:
