One Windows multi-monitor feature I missed, though was the ability to drag each screen's position around: My mouse cursor entered the screen from the wrong direction. It also works with Apple TV-connected HDTVs as well as HDMI and Thunderbolt monitors. It requires no configuration-for real: I plugged in a Dell monitor and immediately saw the Mavericks wave wallpaper.
Mac OS X Mavericks now follows suit, allowing multiple monitors to show the Dock and menu bars. Multiple Display Support One of Windows 8's big boasts was its multiple display support, which allows users to show the taskbar on more than one screen, and even stretch a wallpaper across displays. Look up words, make use of highlighting and notes, and rest assured that everything is synced among all your Macs and iOS devices. Like the latest iTunes desktop app, a button switches you between your library and the store, which boasts over 2 million books (compared with Amazon Kindle's claimed 2.7 million and Barnes & Noble Nook's 3 million). That said, iBooks for Mac is a well-done piece of software, just as you'd expect from Apple. IBooks That book-reading software is the top-billed new feature in Apple's new desktop software gives you a hint about the update's evolutionary rather than revolutionary nature. To put Apple's new OS through its paces, I installed Mavericks on a 15-inch MacBook Pro with Retina display and a 2.3GHz Core i7 CPU ( at Amazon). A new organizational tool, Tags, works the way tagging in photo apps has worked for years: attach a text keyword to any file, and you'll be able to find it quickly in a Finder sidebar. Also improved are some system tools, including multiple display support, notifications, the Finder, and Keychain password management, which now can sync among all your Macs and iOS devices.
