"This update fixes a problem that may cause iTunes to quit if you switch between wired and wireless syncing and addresses an issue that may require you to log into the iTunes Store repeatedly," the official release notes state.
iTunes 11.0.4 is now available for download from the Mac App Store, and will be provided through Apple's website.
The last iTunes update, version 11.0.3, arrived last month, bringing a new MiniPlayer featuring artwork and a progress bar. That update also included an improved Songs View in the software.
The last major update to the software was released as iTunes 11 last November. It featured a complete overhaul of the application's design, along with a new storefront and tighter integration with Apple's iCloud suite of services.
