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

This week, readers wrote in with questions about whether it is possible to install Windows on an external hard drive for use in Boot Camp, how to set up Time Machine to back up home folders stored on secondary drives, and how to disable the yellow tooltip popups that appear over URL links in many OS X applications. I welcome contributions from readers, so if you have any suggestions or alternative approaches to these problems, please post them in the comments!

Question: Using Windows 7 … Read more

If you were hoping to watch last weekend's Coachella concert on your iDevice, you just missed your chance: although the event was streamed live on YouTube for free, the iOS YouTube app doesn't support live streaming.

For those unaware, YouTube offers a variety of live content, everything from concerts (natch) to news and sports.

The iOS streaming feature joins a "Send to TV" option introduced back in February, … Read more

If you listen to music on your Mac while at work, you may use earbuds so as not to disturb co-workers; however, this does have a tradeoff. When using both earbuds, you can drown out others who might be trying to get your attention, but if you only wear one earbud, you will miss the parts of stereo recordings on the channel for the bud you left out, which in some cases can make a dramatic difference in the sound you're hearing.

You can avoid this by setting your Mac to use Mono output. This will combine all audio … Read more

NEW YORK -- Firefox Mobile OS will launch this summer in five countries, Mozilla CEO Gary Kovacs said at the All Things D conference here Monday.

A spokesman for the company reiterated that the company had announced initial launch countries on February 24 when it was showing off the mobile OS at the Mobile World Congress trade show in Spain.… Read more

Facing what appears to be an indefinite ban of its software from Apple's App Store, French app discovery service AppGratis is trying to make a case for itself with an Internet petition.

A new page that went up over the weekend gives users a special e-mail address to send their pleas to if they want to "save" the company. So far, the initiative has accumulated more than 608,000 such messages, according to the page's official tally.

AppGratis was removed from Apple's App Store earlier this month. The software would alert users to a daily … Read more

You've got a high-resolution camera, an Internet connection, an iPhone or iPad, and an itch to share your photos with your friends and the world. What to do? Enter the free iOS photo-editing app Pic Stitch, allowing you to easily combine, filter, and change photos on your device and share them with friends.

Pic Stitch's interface is surprisingly simple to navigate considering how many features it includes. The free version of the app does have periodic ads, and quite a few features require paid upgrades to use in full, but every core feature is available for free.

Stay Alight! (iPhone|iPad) is a destruction game that is somewhat similar to Angry Birds, but in this game, you play as Mr. Bulb and it's your job to take out the monster microbes.

Instead of flinging objects like you would in Angry Birds, with this game you're shooting an energy projectile that bounces off walls. So to get the best trajectory and power, you'll need to both think about where your targets are and how the projectile will bounce through the level to hit as many monster microbes as possible. Like many games in this genre, … Read more

Every parent knows (or should know) the importance of reading to their kids. And when it comes to stories adults and toddlers alike can enjoy, it's hard to beat Dr. Seuss.

Of course, browse the aisles (real or virtual) of any bookstore and you'll see that your average Dr. Seuss hardcover can run $10-15. Ouch!

That's why I continue to be a big fan of Oceanhouse Media's Dr. Seuss e-book apps, which not only provide the complete Seuss experience (and then some), but also save you considerable coin.… Read more
