In OS X Yosemite, many of the Aqua elements and icons were simplified and flattened, following a similar design change in . Apple incorporated the same saturated frosted-glass effect, called "Vibrancy", across the system. Examples include the Dock, the menubar, sidebars, Notification Center and Mission Control. A similar effect was applied to toolbars, but they maintained their gray appearance. Toolbar buttons became white and Apple introduced a more compact type of toolbar that removed the window title, but retained the toolbar buttons (for example, in Safari). Certain controls, such as checkboxes and radio buttons, gained animations, whereas animations in other places were removed, such as the "poof" animation when removing an icon from the Dock and the "cube" animation when fast-switching to another user account. Apple changed the system typeface to Helvetica Neue. Yosemite also added a 'dark theme' you can turn on in the settings which makes the dock and menu bar black.
