在 Mac OS X 10.9 及其之后版本的系统中,这个选项被取消了,而且通过该命令行来设置对系统本身也不起作用了。 所以在 Yosemite 中使用该命令行只对一些比较老的软件起作用,对于系统包含的软件和大部分为 Mac OS X 10.9 以后的系统开发的软件已经不起作用了。. OS X 10.10, aka Yosemite, sports a more modern look and bridges the gap between Apple's desktop and mobile devices. The new Continuity helps you hand off tasks from iPhone to iPad to Mac, but that.
Apple announced OS X Yosemite on June 2, 2014, a powerful new version of OS X redesigned and refined with a fresh, modern look, powerful new apps and amazing new continuity features that make working across your Mac and iOS devices more fluid than ever.
The new Today view in Notification Center gives you a quick look at everything you need to know, all in one place; iCloud Drive is located within the Finder and can store files of any type; and Safari has a new streamlined design that puts the most important controls at your fingertips.
Mail makes editing and sending attachments easier than ever; Handoff lets you start an activity on one device and pass it to the other; and Instant Hotspot makes using your iPhone’s hotspot as easy as connecting to a Wi-Fi network. Yosemite even gives you the ability to make iPhone calls on your Mac.
