I can't test this, but Apple claims that some of these new technologies can reduce CPU usage by 72 percent, and I've certainly noticed that battery life on the 2012 MacBook Pro that I've been using with Mavericks has noticeably better battery life than it did under Mountain Lion. Meanwhile, deep below the surface, new power-management features extend the battery life on your laptop. But as you start using it, you discover features that suddenly became much easier to use-for example, when a new-message notification slides into the upper right of the screen, you can click on a Reply button and answer directly from the notification, without switching back to the Messages app. Just as with Mountain Lion, Lion, and Snow Leopard before it, OS X Mavericks smoothly slots in a few hundred new features, but doesn't force you to forget the things you already knew about the operating system or send you on wild-goose chases for features that you used to rely on.Īt first glance, OS X Mavericks looks a lot like OS X 10.8 Mountain Lion, with the addition of a Maps app and an iBooks app that iPhone and iPad users have had for years. But in the major upgrade to Mavericks last October, Apple proved that it knows exactly what's needed in an operating system upgrade. OS X 10.9.2 Mavericks (free upgrade) not only addresses the "goto fail" SSL issue, it also adds some feature boosts that will be welcomed by Mac users-in particular those who also partake in Apple's family of mobile devices running iOS. New color-coded tag feature lacks some conveniences.ĭespite recent security problems, Apple's Mac desktop-and-laptop operating system remains PCMag's top choice in the genre.Minor inconsistencies in deep features like keyboard shortcuts.
