Mavericks, like Mountain Lion, is available only by download, not on DVD or a USB stick. ![]() Any Mac that can run Mountain Lion can also run Mavericks, and you install the new version by downloading it from the App Store. ![]() If you buy a new Mac, you'll get Mavericks installed on it. Apple has stopped naming OS X versions for big cats and started naming them for California landmarks-Mavericks is a famous surfing site, and the default desktop image in Mavericks is a spectacular wave. The most obvious change between Mountain Lion and Mavericks is in their names. Other mostly-invisible improvements include major enhancements to security so that apps and browser plug-ins are more tightly controlled than before. 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.How to Set Up Two-Factor Authentication.How to Record the Screen on Your Windows PC or Mac.How to Convert YouTube Videos to MP3 Files.How to Save Money on Your Cell Phone Bill.How to Free Up Space on Your iPhone or iPad.How to Block Robotexts and Spam Messages.You can leave a comment on my original post. Remember to disable the root user again for your own safety when you get a change. OS X will now start as if you’ve never setup your computer. When your computer comes back you’ll be able to login as root, using the password you’ve specified. Now click the little Apple Icon at the top left and log yourself out. ![]() Speaking of which, you’ll have to give the root user a password when prompted. If ever you want to disable root, select Edit – Disable Root User (or change its password). Thankfully we won’t have to worry about what it says:Īll we’re interested in is the standard menu bar at the top of the screen: select Edit – Enable Root User and hike it out of here. Now select Network Account Server – Join… and another scary window appears. If any of the following options are greyed out, simply click that little lock icon (and type in your computer password): To enable it, head over to System Preferences – Users and Groups and select Login Options at the bottom left. Even power users on a Mac have very little reason to use root – which is why it’s disabled by default. ![]() The root user can read, write and delete every file on the system and – when placed in the wrong hands – destroy the entire system in a flash. Root is the most powerful user in Linux and UNIX systems, from which OS X is derived.
