Apple has today released the fourth beta to their new OS X Yoesmite Developer Preview, which came alongside the release of iOS 8 beta 4 earlier, and comes with a number of new features to their OS for the Mac desktop and laptops.

These new features mainly center around the release of a new version of iTunes, dubbed iTunes 12, it comes with a completely new look that has been streamlined, and redesigned in line with the rest of Mac OS X Yoesmite.

Alongside which iTunes 12 also has new family sharing features.
