(If you haven't been paying attention, you can read about its major new features in our initial coverage in '[1]Apple Unveils iOS 8 and OS X Yosemite at WWDC,' 2 June 2014). Yosemite is available for free in the [2]Mac App Store as a 5.16 GB download. Refer to [3]Apple's system requirements to see if your Mac can run Yosemite (most will), and if it will support all of Yosemite's new features (many older Macs won't, due to Continuity's need for Bluetooth 4.0). The most noticeable change in Yosemite is a new visual design that takes its cues from iOS. It also brings compatibility with Apple's new iCloud Drive service and offers a slew of Continuity features to make working between Apple devices easier. As always, we recommend waiting a few days before updating to see if any major issues develop. In the meantime, we recommend checking out Joe Kissell's '[4]Take Control of Upgrading to Yosemite' and Scholle McFarland's '[5]Yosemite: A Take Control Crash Course.' We're working in the final details that couldn't be known until release into both and anticipate that they'll be available later today ' we'll write more about them separately once they're done. Following Yosemite will be iOS 8.1 and the launch of Apple Pay, on 20 October 2014. With [6]iOS 8.1, Apple seeks to remedy common user complaints, most notably by bringing back the Camera Roll in the Photos app. The update will also open up the beta of iCloud Photo Library to all. iCloud Photo Library allows you to sync all of your photos and videos between your Apple devices (as long as they're running iOS 8.1, Yosemite, or Apple TV 7.0 or later). However, the Mac version of Photos, which will bring iCloud Photo Library support, won't be available until early 2015, so access via the Mac will be limited to iCloud's Web interface until then. iOS 8.1 also brings [7]Apple Pay support to the iPhone 6, iPhone 6 Plus, and the new iPad models, although support is currently limited to the United States (for details, see '[8]Apple Pay Aims to Disrupt Payment Industry,' 9 September 2014. Since the initial announcement last month, Apple has signed up 500 more banks to the program, in addition to credit card companies American Express, MasterCard, and Visa. You will be able to use Apple Pay at a growing number of major retailers, such as American Eagle, Foot Locker, Macy's, McDonald's, Office Depot, Panera Bread, Subway, Walgreens, and Whole Foods. If you want help with iOS 8, we hope to have it soon, in the form of my '[9]iOS 8: A Take Control Crash Course.' You can pre-order now, and we're working hard to integrate details about features that weren't fully operational before the release of Yosemite, along with the forthcoming changes in iOS 8.1.
