Got Bluetooth problems like a glitchy mouse or an unreliable keyboard? Maybe a screwy trackpad or poor headphone connection? Any of those problems could result from a glitch in your Mac’s Bluetooth radio. Maybe you’ve already tried everything — unpairing your devices, resetting them or even creating a pristine new user account on your Mac solely for troubleshooting purposes.

You may even know about the hidden Bluetooth menu that appears when you option-click on the Bluetooth menu bar icon. But did you know that there’s another, deeper, super-hidden menu with extra troubleshooting tools? There is. Here’s how to fix Bluetooth problems when nothing else seems to work.

Christmas time means packing up your daily troubles, forgetting work for a week, and heading home to… troubleshoot your parents’ broken computers and gadgets? Oh man, is it that time of year again already? That’s the problem with being the family’s only geek – you get handed all the geek jobs. However, you can turn this to your advantage, and make it a lot easier, by going in prepared. Check out our Holiday Troubleshooting Guide right here.

If your Mac is sick, the first step is to restart it. But did you know that there are several tricks you can perform while your Mac is starting up?

Many of these are advanced Mac diagnostic tools, which shouldn’t be used unless you really know what you’re doing. But some not-so-secret startup keyboard combos will remove a stuck disk (if your Mac is old enough to even have a disk inside), let you boot your Mac from a USB drive, or to turn your entire computer into one big storage disk to connect to another computer.

If you have a 2011 MacBook Pro that is wonking out like it was haunted by a Japanese ghost, you’re not the only one. It appears that a massive number of early-2011 MacBook Pro owners with AMD graphics are having issues with system crashes and hardware problems, with failure rates reaching a critical mass in recent weeks.

So, it happened that a friend of mine turned off Bluetooth on her Mac mini, and then turned it off for the evening. When she got up the next morning, her Bluetooth keyboard was on, as per usual, but she couldn’t log in on start up, as her Mac did not see her keyboard.

She was worried that she’d have to go borrow or buy a wired keyboard, plug it in, and enter her password, then turn Bluetooth on again to make her wireless keyboard work again.

Luckily, that’s not what had to happen. Here’s how we solved it.

While many of us already have our eyes set on the new iPhone, which Apple will likely release this fall, there are still millions of people using the iPhone 4.

Released on June 24, 2010, the first round of iPhone 4’s are about to hit their two-year anniversary. This means that those who purchased an iPhone 4 along with the AppleCare protection plan, which effectively extends warranty protection to two years, are about to lose coverage.

If you bought an iPhone 4 in the summer of 2010 you should take some time to examine it in order to ensure that no part of it is showing signs of defect. Here’s what you need to know.

Last week, Microsoft pulled its Service Pack 2 update for Office for Mac 2011. As we reported earlier in the week, the update could result in the corruption of the Office database and issues with Office identity files could make resolving the problem difficult. After initially posting advice about the update and its potential problems, Microsoft pulled it from the company’s update servers.

Microsoft has now re-released the update. In addition to not creating the problems that plagued the original update, the new version will also correct problems for users that had downloaded the initial.

The entire situation illustrates why most tech companies, including Apple, advise business customers to wait before rolling out any new updates.

Jailbreaking has its many benefits, but there’s always a risk that installing a certain tweak or app from Cydia will cause something in iOS to go haywire. It doesn’t happen often, but when it does, you want to be able to fix the problem without having to restore and lose your jailbreak.

Luckily, there’s a relatively easy way to troubleshoot your jailbroken iOS device and find out the exact tweak that’s causing the problem.

For a lot of people, yesterday’s 10.7.3 update for OS X Lion went without a hitch using Software Update, but for a sizable (and understandably annoyed) minority, the update resulted in the widescale crashing of apps and the replacement of stock Lion UI elements with a mysterious “CUI?” error.

If you’ve been bit by this error, you have our sympathies, but buck up! In most cases, it’s a pretty easy thing to fix the update and get Lion working as it was.
