Apple also announced that the new version of Mac OS X (10.9 Mavericks) is available now and is free to all Mac OS X users. It includes better multi-monitor support, tabs in Finder, and a number of performance optimizations. The Macbook Pro is getting updates to the 13" and 15" models, which are now running on Intel Haswell processors. They both have PCIe SSDs, 802.11ac Wi-Fi, and Thunderbolt 2 support. Apple also talked about the redesigned Mac Pro line. As you may recall from WWDC, the new model takes up about about 1/8th of the volume as the old one. It's cooled by a single fan, uses 70% less power than the earlier model, and puts out 12 dB of noise when idling. It'll be available in December. On the software side, Apple has been updating a lot of their software to add 64-bit support and mesh with the new iOS 7 style of design. This includes iPhoto, iMovie, and Garageband, as well as the iLife and iWork software suites. iWork is also getting collaborative work features, and it's now free with new Macs and iOS devices.
