I also love Yosemite's new Dock, which dispenses with the odd, 3D version of recent years, replacing it with a flat, translucent background. Apple also revamped the icons for included apps, starting with a new, happier Finder, and you'll find that some elements, such as the Share button, are direct copies of their iOS counterparts. For example, Safari's toolbar is now inline with the 'Stoplight' buttons, and Contacts has lost its traditional title bar in order to conserve vertical screen space. (You can disable most transparent effects by going to System Preferences > Accessibility > Display, and checking the Reduce Transparency option an Increase Contrast option makes many buttons and similar interface elements more defined.).Īpple simplified and compacted many window toolbars. But in others, it helps you focus on the main content area, and it adds a feeling of depth to the otherwise flat design. The translucent effect can be a bit distracting in some apps, for example, in Preview's sidebar. Translucency is everywhere in Yosemite, in toolbars, sidebars and more. The system font is now the thinner Helvetica Neue interface elements that formerly had texture or weight are now flatter and more colorful gradients are subtler or have been eliminated completely.

More than with any previous update to OS X, Yosemite offers a significant visual overhaul. Apple's other official requirements are 2GB of RAM and 8GB of available storage I recommend at least 4GB of RAM and 10GB or more of free drive space you'll simply have a better experience with those resources. To install Yosemite, your Mac must already be running 10.6.8 Snow Leopard or later to download the new OS from the Mac App Store.

MacBook (Late 2008 Aluminum, Early 2009 or newer).
