How to activate dark mode for OS X Yosemite

In the latest OS X Yosemite, Apple has added a feature called "Dark Mode", which turns the transparent menu bar and dock from light gray to black. Although a small feature, this is what many Mac users have long wanted. How does the dark mode open?

This feature can be turned on and off in the "General" Panel of System Preferences. As shown in the image above, there is a new option to use the darker menu bar and dock in the Appearance drop-down menu. When checked, the system's menu bar, dock placeholder, and drop down menu background will all turn black.

When Dark mode is turned on, the system fonts and menu bar icons become black, but unlike the Yosemite of the test version, the system fonts are not bold. For some users, this display mode may have some difficulty reading the text. If you don't like it, you can uncheck the "Use LCD font smoothing when available" option, which makes the font look slimmer. But note that the overall nature of the change, that is, the black font will also be thinner.

Although the first-party menu bar icon will also change from black to white, most third-party apps have not changed. Because most menu bar icons are black, at least the edges are black, and the Apple system exerts a small piece of white at the bottom of each shape. This approach brings a slightly raised look, though not ideal, but it's a good alternative before developers make their own white icons.

If you want to further adjust your desktop layout to fit Dark mode, you can adjust the traditional settings and display options. For example, changing system tones from blue to graphite in System Preferences > General > looks makes the system's color style less lively and bold.
