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:

If you are running OS X Lion or Mountain Lion and need to see some quick information about your Mac's hardware, you can do so by selecting "About This Mac" from the Apple menu, and then clicking the "More Information" button to launch Apple's System Information tool. This tool can be used to generate a detailed system report, but by default will show a brief summary window that includes a breakdown of storage usage.

The storage view shows your hard drive and includes a small diagram that breaks down the amount of space used … Read more

To burn discs with your PC, you need two things. The first is a CD burner, or (better) a DVD burner, or (better still) a Blu-Ray burner. The second is disc-burning software. For the first, you're probably limited by the burner you already own, and your burner's capabilities will determine what kinds of disc you can burn, how much and what kind of data they can hold, and how long it takes to burn them. But for the second requirement, the burning tool, you have a lot more choices, and a lot of them are free. Active Data … Read more

Research In Motion will hold its apparently final BlackBerry 10 "Portathon" this weekend.

Running from 9 a.m. PT today to 8:59 p.m. PT tomorrow, the event will allow developers to port their applications available on other mobile platforms to BlackBerry 10. Each approved app will net the developers $100, up to a maximum of 20 applications. To sweeten the pot even more, RIM will enter all developers who submit five or more apps into a drawing for a free BlackBerry 10 Dev Alpha device.

RIM has been running Portathon events for the last several weeks … Read more

LAS VEGAS--Sight tracking sounds like a new PC interface we might actually use. And anything that helps push wireless charging forward will get our attention. But of all the still-developing technologies we saw at CES, it's the 3D Systems CubeX 3D printer that has us the most excited.

Makerbot announced its own new printer, the Replicator 2X, at this year's show. It's a fine-looking machine, and its print quality looks superb. 3D Systems got the nod for a nomination because its CubeX does things we haven't seen before in a consumer-approachable 3D printer.

The CubeX … Read more

Irritated by your car's built-in GPS? You're not alone.

More car owners are less happy with their factory-installed navigation systems than in the past, says a report out today from J.P. Power and Associates.

A survey of drivers conducted late last year found satisfaction with their navigation systems down 13 points from the prior year. The level of satisfaction was down in all of the six factors measured, but ease of use was the biggest complaint, dropping in score by 25 points.

The other five factors included in the study were routing, navigation display screen, the speed … Read more

LAS VEGAS--No 3D printer vendor had a cavernous booth at CES. Only MakerBot held a press conference, but it was only a low-key presentation on the show floor, not some over-produced auditorium-filler.

And yet, every time I walked by a booth owned by a 3D printer manufacturer, the crowds were there in force. People are clearly excited by 3D printing here, and they had a variety of examples to learn about at the show.

I checked in on all of the major 3D printing vendors here at the show. Here's what I saw.

LAS VEGAS--Usually at CES time, you can expect Panasonic to roll out slightly updated versions of its Blu-ray home-theater-in-a-box (HTIB) solutions, featuring six-to-eight plasticky speakers and a whole lot of proprietary speaker wire. But CES 2013 is different.

Panasonic is ditching its standard assortment of HTIBs, opting instead for three new sound bar and convertible sound bar models. The SC-HTB770 and SC-HTB370 both feature a similar design; you can use them in the traditional horizontal alignment or you can break apart the sound bar and use the pieces as separate speakers. The SC-HTB770 converts into a 3.1 system, with … Read more
