If you need to adjust network settings on your Mac, the quickest route is to do so through the OS X system preferences and menu extras. However, you can also make these changes -- adding and removing ports, creating new locations, switching to DHCP from manual configurations, changing MTU sizes, and managing 802.1x profiles, among others -- via the command line.

The utility for doing this is the command "networksetup," which can be used to quickly apply a change to a specific network property. This tool covers every aspect of the Mac's network setup and you … Read more

Apple's Mac systems come with a basic audio controller for playing through the system's internal speakers or through the audio ports to headphones or a stereo system. However, if you would like to use a different controller such as a multi-channel USB interface for recording with GarageBand, Logic, or other use, then you can add it to the system and set it up to be used instead of Apple's controllers.

While useful to have, if you configure your system with multiple interfaces then you might run into an issue where the system could revert to its internal … Read more

MacFixIt Answers is a feature in which I answer Mac-related questions e-mailed in by our readers.

This week, readers wrote in with questions about managing contact images in Address Book, the lowdown on the rather negative community reaction surrounding the MacKeeper utility, and errors in gathering Application information in the System Information utility. I welcome views from readers, so if you have any suggestions or alternative approaches to these problems, please post them in the comments!

Question: Managing the Recent section for contact images in Address Book MacFixIt reader Lars asks:

Many programs, such as Microsoft Office, support their own interfaces for various fonts you may have installed on your Mac; however, many other programs like TextEdit and Apple's Pages use Apple's central Font panel to provide font management. This panel can usually be invoked by pressing Command-T in programs that support it, where you will be presented with a column-oriented view of font collections that you can navigate through, select, and set the size for.

While convenient for quickly selecting and setting font sizes, the Font panel also contains a number of additional features that can be applied … Read more

As a social network built on keeping things short and sweet, it's no surprise that Twitter released today a secondary app that lets users (Twitter and otherwise) shoot and upload 6-second videos.

Of course, no later than a few hours after its launch, Vine was already being called the "Instagram for video," as users began sharing short clips of kids, stop-motion drawings, food, and, of course, puppies.

Currently, Vine is only available for iOS, but Twitter assures users that its app will be coming to other platforms "soon."

The app is pretty simple … Read more

OS X is an account-based system, in which individual users have their own accounts storing their own settings and data. When you set up a user account, the system will ask you for your name and then based on that will create a short username the system will use to identify your user account.

This short username is the true username of the account, but you can use the short name or your full name at the log-in window. Since the system initially generates it for you, it's easy to overlook the fact that you have the chance to … Read more

While setting your Mac to automatically sleep after a period of inactivity has its energy-saving benefits, you may find that the system will go to sleep even when it is churning through data (e.g., applying a lengthy filter routine to groups of images).

This issue happens because Apple has implemented some changes to the latest versions of OS X that result in different requirements for the system to determine if it can go to sleep, and one of these is a new dependence on applications to invoke a "power assertion" to keep the system from going to … Read more

The first question is, what do you want from your hi-fi? Do you want to play LPs, CDs, or an occasional movie? Next, where will you put the speakers, and how large or small do they need to be? I'm writing this blog post for folks trying to put together the best-sounding hi-fi they can on a fixed budget. That's why I won't be covering wireless systems, because dollar for dollar, the better wired speakers always sound better than wireless models.

Setting the budget is the next logical step. I've written about an amazing-for-the-money $70 hi-fi system, … Read more

Smartphones and tablets are often used for quick access to address book content and calculators, but there are times when you might find yourself looking up a phone number or running a quick calculation on your Mac and need to take the results with you to another location in the room. Instead of writing it down on a notepad, if you will be in view of your Mac from a different location then you can use some quick features in the Contacts and Calculator applications to be able to see the results from a distance.

Both the Calculator and Contacts … Read more
