Sources reveal Apple's new-look interface for Mac OS X Lion's Finder, Mail, and other apps
Scroll bar settings, iOS-style switches for menus
As revealed by AppleInsider earlier Thursday, Mac OS X 10.7 Lion features overlay scrollbars similar to those in iOS. If a user's pointing device (such as a TrackPad or Magic Mouse) supports both horizontal and vertical touch scrolling, the scrollbars are hidden during normal use.
Scrollbars will appear as an overlay on top of the window's content while the user is scrolling. The bars will also remain visible briefly after scrolling, to allow users the option to drag the scrollbar.
If a user does not have a device attached that is capable of scrolling, the scrollbars will remain on the screen. In addition, users can turn on the "legacy scrollbar" option in System Preferences.
Other iOS-style elements have also been added to the Mac OS in Lion, with switches that resemble those that might be found in an application on the iPad.
New privacy settings, parental controls
A new privacy section has been added to the Security option in System Preferences. It allows users to choose whether diagnostic data will be sent to Apple, and also whether location services are enabled on their Mac. These options are similar to the location services settings on iOS devices.
