Taking a screenshot in OS X is a popular option for capturing activity on your computer, whether for communicating instructions to people or documenting events that are happening on your system. Usually screenshots are taken when sitting at the local system, but if needed you can also do so remotely by several different means.

The easiest way to take a remote screenshot is by using the Screen Sharing service in OS X. By enabling this in the Sharing system preferences and then connecting to the remote system to view its screen, you are provided a couple of ways to take … Read more

Readers have from time to time requested a list of the "test" tracks I use to evaluate gear. It's a long list, mostly recordings I've used for many years and heard on hundreds of products, and recordings I made myself or from sessions I attended. They work for me, but wouldn't necessarily help you. More than any specific tracks, I recommend starting with music you know best, favorite tunes you've listened to for years, and then listen to how the speaker, headphones, etc., you're considering changes, improves, or degrades the sound of your … Read more

The OS X Character Viewer is a system-wide text entry service that allows for quick access to numerous special characters from fonts in your system. While the use of keyboard modifier keys (Shift, Control, and so forth) allow for quick access to some common alternative characters, there are numerous Greek, currency, math, and emoticon symbols that can be accessed through the Character Viewer panel in OS X.

This panel can be accessed from the Edit menu in most applications, but can also be opened using keyboard shortcuts or the input menu, as outlined in this previous article.

Cell phones can make fantastic holiday gifts, but purchasing one for someone other than yourself is more complicated than shopping for other gadgets. Unlike a laptop or a shiny new camera, a cell phone requires a service plan to use any voice or data features (otherwise you wind up with a very expensive paperweight). In most cases, you won't even be able to leave the store or complete your online order until you get that angle set up. And beyond just being an additional expense, that service may require a long-term commitment.

There's no reason to stress, though, … Read more

People love sound bars for a lot of good reasons: they eliminate most of the wiring and setup hassles associated with traditional 5.1-channel home theaters, they don't take up a lot of space, they are less expensive than subwoofer/satellite packages, and since most sound bars are self-powered, you don't need to buy an AV receiver. A skinny sound bar positioned under a sleek display is certainly a more appealing solution than a 5.1 or even stereo pair of speakers. There's just one problem: sound bars can't fill a room with sound nearly as well as separate speakers can.… Read more

AT&T today announced new international roaming plans that will go into effect tomorrow. The Europe and Rest of World options will join the Canada and Mexico plans that the carrier announced last June.

For each region, customers can choose one of three packages that delivers a set amount of minutes for a flat monthly rate. Of course, going over your allotment will result in hefty overage fees and exact coverage will vary by country. Also, keep in mind you'll need a quad-band handset that supports the 900 and 1800 GSM networks that are used outside the United … Read more

CoreStorage is Apple's volume manager that provides an interface between the OS and physical volumes on the drive. It was introduced in OS X Lion for its full-disk encryption options with FileVault 2, but in addition allows for volume spanning, where multiple drives in the system can be combined into one logical volume for the OS to use.

The CoreStorage volume-spanning feature not only increases a single volume's storage beyond the capacity of a single drive, it also prioritizes storage to the primary drive in its logical volume. This means that if you use an SSD as the … Read more

iPhone troubles? Let me guess: an update won't install properly. Or an app keeps crashing on you. Or you can't get your Bluetooth connection to work.

Problems like these often drive frazzled users to the Apple Genius Bar, which, of course, requires a reservation via the Apple Web site. Before you can make one, however, Apple now suggests this:

It's true: Apple wants you to try the iPhone equivalent of Ctrl-Alt-Delete before you make a special trip to the Apple Store and, well, watch while a Genius resets the phone for you.

Although this may come across … Read more

Emoticons have become some of the most commonly used symbols when communicating using computers and cell phones. Starting with combinations of text characters, smilies evolved into emoticons with the development of Unicode fonts that include complementary images for common smilies. For instance, applications like iMessage and iChat in OS X will make use of emoticons, automatically substituting an image of a smiling face from an emoticon font if you enter the ":)" text for a standard smile.

If there are other emoticons you often use, then you can use the system preferences to set up your own global text … Read more
