How do I disable the Minimize (command-M) shortcut in Mavericks? I want to unset the Cmd+M shortcut but I can't seem to find it. I've checked  System Preferences &gt; Keyboard &gt; Shortcuts but no luck there. I've even tried running defaults write -g NSUserKeyEquivalents -dict-add 'Minimize' '\0' to no avail.
You don't need to install any additional software.


Go to System Preferences > Keyboard > Shortcuts > App Shortcuts
Click the  button below 
Enter "Minimize" (use "Minimize All" to override minimizing all windows with ⌥⌘M) into the Menu Title text input field.
Assign some bizzare key combination that you won't press by accident.
Repeat steps three and four for "Minimise" (alternate spelling) which is required for some apps.
Close the window to save the changes.




I'm aware that this is not really "disabling it" but the result is effectively the same and without depending on 3rd party software.
