Taking a screenshot in OS X is a popular option for capturing activity on your computer, whether for communicating instructions to people or documenting events that are happening on your system. Usually screenshots are taken when sitting at the local system, but if needed you can also do so remotely by several different means.

The easiest way to take a remote screenshot is by using the Screen Sharing service in OS X. By enabling this in the Sharing system preferences and then connecting to the remote system to view its screen, you are provided a couple of ways to take … Read more

After making changes to the drive configuration in OS X you may run into an issue where the system will not boot as fast as it previously did. In these cases the system may sit at the gray boot screen for a while before the OS loads, but when it finally does, the system will otherwise run just fine.

This problem can happen after several types of drive configuration changes, which include replacing a faulty drive, upgrading the drive to a larger or faster one, or migrating to a new storage approach such as a custom Fusion Drive setup in OS X Lion or later.… Read more

OS X's encryption service, FileVault, originally stored users' home folder contents in encrypted disk images. In OS X Lion, FileVault now uses Apple's new CoreStorage volume manager to encrypt the entire disk. With CoreStorage, the OS configures a small hidden partition with a preboot welcome screen that looks like the standard OS X log-in window and contains user accounts that are authorized to unlock the volume and cause the system to load and automatically log in to the account specified on the preboot screen.

Unfortunately, while more secure and while offering a relatively seamless experience when sitting at … Read more

If you own one of Apple's latest 2012 Mac Mini systems and are attempting to update it to the latest version of OS X, you may find the update is not available via the App Store's Software Update service. Furthermore, if you download the manual updater for 10.8.2 and attempt to install it, you will see an error that states: "Error: OS X Update can't be installed on this disk. This volume does not meet the requirements for this update."

The reason for this error is the 2012 Mac Mini requires a special … Read more

The OS X character palette is a convenient option for accessing multiple unicode symbols that are part of modern font collections. Not only can you use fun items like emoticons, but you can also enhance writing with scientific and mathematical symbols, foreign script characters, symbols, and even Braille.

Having these characters in the character palette makes managing them far easier than prior approaches in which unique symbol and dingbat fonts had to be used.

If you would like to use the OS X character viewer, it can be accessed in a few different ways:

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

This week, readers wrote in with questions about hiding the menu bar in OS X, a "formatter failed" error when erasing hard drives, alternative configuration possibilities for Apple's Fusion Drive technology, and whether or not a Mini DisplayPort cable can be used for Thunderbolt connections. I welcome views from readers, so if you have any suggestions or alternative approaches to these problems, please post them in the comments!

CoreStorage is Apple's volume manager that provides an interface between the OS and physical volumes on the drive. It was introduced in OS X Lion for its full-disk encryption options with FileVault 2, but in addition allows for volume spanning, where multiple drives in the system can be combined into one logical volume for the OS to use.

The CoreStorage volume-spanning feature not only increases a single volume's storage beyond the capacity of a single drive, it also prioritizes storage to the primary drive in its logical volume. This means that if you use an SSD as the … Read more

Apple's recently introduced Fusion Drive system is available in Apple's current Mac Mini and will be included as an option for other Mac systems starting in November and December of this year. This new drive setup has its benefits, but also some limitations, and to address these Apple has issued a FAQ that addresses troubleshooting and how the drive can be used and configured.

A Fusion Drive is essentially a hybrid volume that spans both a solid-state drive (SSD) and a hard drive installed in the Mac. As large SSD drives are unfortunately still rather expensive, to get … Read more

If you have a MacBook system that contains dual graphics cards, then you have the option of enabling either the internal graphics or the discrete graphics card, depending on the hardware demands of the tasks you are running.

Integrated or "internal" graphics functions are included on the Intel processor in your Mac (though some prior Mac systems used Nvidia chipsets with Nvidia-branded internal graphics). This graphics option is relatively slow but also draws far less power than a dedicated graphics processor. The integrated graphics are powered fully when the system is turned on.

If your system includes a … Read more
