Apple's Xserve computers were a rack-mountable line of Macintosh systems designed for enterprise use; however, in 2011 Apple abandoned the project, leaving only its Mac Pro and Mac Mini with available server options. Though anyone can download the OS X Server tools from the Mac App Store and convert any current Mac into a server system, some may wish to get a rack-mounted setup going again.

Fortunately, even though the demise of the Xserve means there aren't officially supported rack-based options from Apple, there are some ways you can get your Macs back into the rack. Of course, … Read more

There is no question that regardless of the computing platform you use, malware happens. To help prevent these and other unwanted programs from running, Apple includes a data execution prevention routine called GateKeeper, which offers three layers of protection. The first allows everything to run, the second allows only applications signed with a valid Apple Developer ID to run, and the third allows only programs distributed through the Mac App Store to run.

Apple provides the Developer ID option with the assumption that most who use its Developer program create legitimate and trustworthy code, since their works will be easily … Read more

Mailbox, the popular e-mail app snapped up by Dropbox earlier this year, has redesigned its app for the iPad.

The new app, which currently only works with Gmail accounts, has the same functions as the old app. It lets users organize their e-mail using swipe motions with the ultimate goal of reaching "inbox zero."

Mailbox CEO Gentry Underwood said there were a lot of requests for an app designed specifically for the iPad. Formally, users could use Mailbox on any iOS 6 device, including the iPad, but the layout was created with smaller devices in mind.

The new … Read more

Google made searching in Chrome for Android a bit easier with an update Wednesday to the browser.

The latest stable version of Google Chrome 27 for Android (download) now displays search queries in the location bar's Omnibox. The change obfuscates the URL display during searches, to show more results and make it easier to tweak the search terms, according to the Google blog announcing the update.

Another tweak hides the location bar entirely once you start scrolling, so that you can view a Web page in fullscreen. History viewing has finally made it to the tablet version of Android … Read more

The other day I told you about an app that lets you order Polaroid-style prints from your iPhone -- for 99 cents apiece.

Today, let's talk quantity. If you snap a lot of photos and frequently hit up, say, Snapfish or Walgreens for big batches of prints, I've got an interesting deal for you.

For a limited time, you can get a free 100-photo flip-book from Groovebook when you apply coupon code CNETGROOVE at checkout. That's a colossal savings of...wait for it...$2.99!

No, seriously. Without that code, a 100-photo flip-book would cost you exactly $2.99. Shipped. What kind of crazy craziness is this? I'll explain.… Read more

If you are using more than one Mac, or have replaced your Mac with a new one, there are several ways you can migrate your account to the new system.

Conventionally, when you get a new system you are presented with the OS X Setup Assistant, which will guide you through migrating your data from an existing system or a backup.

In addition to Setup Assistant, you can use Apple's Migration Assistant tool at any time to transfer data from one Mac to another. This tool is especially useful for establishing your current user account on another system. Simply … Read more

An ongoing issue for some people who have installed Mountain Lion is the inability to access their systems' internal optical drives. Once installed, inserting a disc results in a couple of noises before the disc is ejected. While this can sometimes happen for burned discs that are no longer readable, it appears to happen for all discs, be they home-burned or commercial.

If this is happening on your system, first try testing the problem with multiple operating systems to see if the problem is hardware or software based. If your system came with gray boot discs, try inserting them and … Read more

"Ok, Glass -- take a picture!"

"Xbox, what's on HBO?"

"Siri, play Angry Birds."

During the reveal of the Xbox One, I was struck by just how many voice commands Microsoft programmed into the device. Kinect brought a rudimentary set of commands to the gaming console, but now everything from opening movies to launching apps can be done via voice. "Xbox, Live TV" may be my new favorite phrase in the living room.

Microsoft's not the only one who's betting big on voice commands. The vast majority of Google Glass'… Read more

Computer malware authors exploit weaknesses in software. Developers combat computer crooks by patching their programs to block malware attacks. That's why we're encouraged to keep our software up-to-date. Every now and then, a software update fails, leaving our systems a little less secure.

I got a first-hand look at the problem the other day when the Apple Software Update program balked at installing iTunes version 11.0.3 on my Windows 7 PC. The installer reported "insufficient privileges" and suggested I log on as an administrator or contact my system administrator. Of course, I was logged … Read more
