Troubleshooting

One of the primary uses of computers is, of course, for media, whether you're watching movies, listening to music, playing a game, or running through a feature-packed slideshow. In the middle of the fun, it can be incrediby frustrating to get interrupted by a loud swoosh as you receive a new e-mail, or a speech alert telling you some other program needs attention.

To avoid such interruptions, of course you can quit the various applications like Mail and instant-messaging clients that may cause them, but this will not guarantee silence, as alerts can still crop up from other sources.… Read more

Besides installing an SSD to replace a mechanical hard drive, RAM upgrades are one of the more significant and beneficial upgrades you can do for a PC system. When it comes to Apple's systems, however, RAM upgrades from Apple itself have been insanely expensive, so my recommendation has always been, unless the RAM is soldered to the motherboard (as it is with the MacBook Air and Retina MacBook Pro), to purchase only the base amount of RAM and then upgrade it yourself later on.

Such was the case with my most recent Mac, a 17-inch 2011 MacBook Pro that … Read more

Apple has released three EFI firmware updates for some of its Mac systems that were released in 2012, which tackle a number of issues pertaining to sleep, Thunderbolt performance, and -- more relevantly to many users -- reliability of Wi-Fi connectivity.

The first update is a Wi-Fi update for all late 2012 Mac systems that improves compatibility with 5GHz-band Wi-Fi signals.

The update includes a new version of the AirPortBrcm4311.kext kernel extension. This update is specific for those running OS X 10.8.2 build 12C2034 (you can look this up by clicking the version number of OS X … Read more

OS X ships with a default configuration and set of settings adjustment options that should work for most people's needs; however, there are times when you might wish to adjust a hidden setting or two, or troubleshoot problems by adjusting settings, databases, caches, and other files that are buried in various system folders. There are numerous online resources that can help, but even if you are comfortable exploring these files, it's good to have a way of reversing any changes you make.

Granted, OS X includes the Time Machine backup service that should back up all system files … Read more

All Mac systems should by default have at least one administrator account for installing programs and otherwise changing the system configuration and settings. However, there may be times, when after an OS upgrade or other major system configuration change, that the administrator privileges of an account might get stripped, leaving you with no way to change a number of system settings.

This occurs quite rarely, but if it does happen, one quick but well-known and convenient trick for recovering administrative status on a system is to activate Apple's OS X setup assistant again. This assistant is generally only used … 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 RAM upgrade options for new MacBook systems, using a Mac laptop as a desktop workstation, song progress options for the iTunes 11 mini player window, and updating external secondary recovery partitions. I welcome views from readers, so if you have any suggestions or alternative approaches to these problems, please post them in the comments!

Question: RAM upgrade options for new MacBooks MacFixIt reader David asks:

One feature in Apple's iCloud service for OS X is its lock option, which allows you to remotely set a PIN for your Mac through iCloud's Find My iPhone service, and require that it be entered to boot the system.

This lock is similar to a firmware password for securing Mac systems. Not only does it prevent booting to alternative boot modes such as Safe Mode or Single User Mode, but it prevents loading in special hardware modes like Target Disk and Internet Recovery so the hard disk cannot be wiped or otherwise accessed.

Unlike the firmware password, … Read more

Apple has released a firmware update that addresses a problem in which displays would flicker to black when used with the 2012 Mac Mini.

The problem, which we reported on in late November, was assumed to be related to one outlined by Intel involving its integrated HD 4000 graphics and a rumor arising from statements made by Intel representatives (which were later changed) that this was a driver-based issue that had been fixed and it would only be a matter of time for manufacturers like Apple to test and release updated drivers.

Rather than drivers, however, yesterday Apple issued an … Read more

A new report is out that suggests a fault may exist in Apple's Time Machine service, causing internal drives to be automatically and silently added to Time Machine's exclusion list, resulting in the service not backing up the data on these drives and not notifying the user of the change.

As outlined on Diglloyd's Mac Performance Guide blog, this problem appears to be situational to setups where many internal drives are being managed. To see this happen, be sure one of your internal drives is mounted and available, and then add it to the Time Machine exclusion … Read more
