OS X Mavericks DP6 - Developer Preview 6 of OS X 10.9. (Commercial)

Fast performance and long battery life are two of the things people love about the Mac. With OS X Mavericks, we wanted to take them even further. So we looked at every level of the operating system, from the foundation up to the apps themselves, for ways to save power while also boosting responsiveness. Learn more...

This update is recommended for all users running OS X Mavericks Developer Preview.

New features:

• iBooks for Mac updated.
• iPhoto updated.

Installation:

• It may be necessary to refresh the App Store Purchases page before Developer Preview 6 will appear in the list of purchases.
• Network migration from earlier versions of OS X requires the Migration Update for Snow Leopard, Lion, or Mountain Lion available form the Mac Dev Center.
• Network migration over Wi-Fi may fail when migrating from OS X Lion.
• Migration from Windows is not supported in Developer Preview 6.

iCloud and iCloud Keychain:
• When enabling iCloud Keychain, a blank sheet may appear. Force Quit System Preferences and retry.
