Apple Releases iTunes 12.4 and OS X 10.11.5

Apple released iTunes 12.4 today with various design enhancements. iTunes 12.4 brings the sidebar back to the left side of the app when you are navigating your library of media, whether that’s music, movies, TV shows, apps, podcasts, or audiobooks. The sidebar is hidden when you navigate Apple Music, the App Store, and the iTunes Store.

Apple has also redesigned the media picker that sits just above the sidebar. Previously the picker consisted of a row of icons representing each media type and could be edited to include only the media types you wanted to show. The new media picker is a dropdown menu that like its predecessor is editable, and adds the name of each type of media next to its icon. Music is the one media type that cannot be removed from the media picker. iTunes 12.4 also includes simplified menus.

It is not clear from the release notes whether iTunes 12.4 includes fixes related to a recently-reported bug that deleted music files from iTunes in rare circumstances that Apple has been unable to reproduce.

Today’s updates also include a minor revision to OS X. Version 10.11.5 of OS X “improves the stability, compatibility and security” and addresses a handful of enterprise-related issues.
