How to quickly annotate and send a screenshot in OS X

A picture being worth a thousand words makes screenshots often the most convenient method for conveying instructions to people. While Apple has a number of screenshot options built into OS X, these often result in intermediary files that can clutter up your computer if you frequently use them.

For example, if you press the classic Shift-Command-3 shortcut to take a screenshot, the image file will be saved to your desktop, where you can open it, crop, and otherwise edit it before sending it to your recipient. With this method, though, you are left with the file on your desktop that … Read more

Eject multipartitioned drives your way in OS X

When you attach an external drive or other secondary drive to a Mac, the volume on it will mount and become available in the Finder and the Finder sidebar for your various uses. To eject the drive, you simply need to click the eject button next to the drive's name in the sidebar, or select the drive and press Command-E, choosing the option to do so from the contextual menu, or even drag it to the trash.

These actions can be performed on one or more selected volumes; once it's ejected, you can safely remove the drive from … Read more

How to encrypt one volume on a drive in OS X

Encrypting data is a convenient method for keeping your data secure, especially when using external hard drives and thumbdrives that may be stolen or lost. While it might be easiest to encrypt an entire drive, sometimes doing so may be a touch inconvenient, especially if the drive is used for more than one purpose.

For instance, if you keep sensitive files on your drive, you may wish to keep it encrypted; however, this prevents you from sharing the drive with others. Therefore, if you want to use the drive to transfer files to another system, you will have to authenticate … Read more

Help protect yourself from signed malware in OS X

There is no question that regardless of the computing platform you use, malware happens. To help prevent these and other unwanted programs from running, Apple includes a data execution prevention routine called GateKeeper, which offers three layers of protection. The first allows everything to run, the second allows only applications signed with a valid Apple Developer ID to run, and the third allows only programs distributed through the Mac App Store to run.

Apple provides the Developer ID option with the assumption that most who use its Developer program create legitimate and trustworthy code, since their works will be easily … Read more

How to create custom PDF compression filters in OS X

Apple's Preview program is the default PDF viewer in OS X, and has a number of options for annotating and otherwise managing PDF files. One of its features is support for Quartz filters, which can be applied to PDFs and image files to convert them, for example into sepia, black-and-white, or gray scale. A Quartz filter can be used to reduce the PDF's file size, but while it's effective at doing so, you may find images in the resulting PDF too grainy to use.

These compression routines are done by adjusting the embedded image quality of the … Read more

Ways to hide applications in OS X

Though OS X offers great multitasking features, having multiple windows open in multiple applications can sometimes hinder concentration. If you don't want to put the application you're mainly working with in full-screen mode, there are other options.

For example, you can minimize windows to the OS X Dock, but this has its limitations, including filling the Dock so it expands across your screen. Additionally, it requires you to click and expand the window from the Dock to preview its contents, which results in the documents being reordered in the Dock when you minimize it again.

If you're … Read more

Quickly add items to the OS X Finder sidebar and Dock

The OS X Finder sidebar and Dock are convenient locations for favorite folders, documents, applications, and locations, and in addition the Dock offers a convenient place for minimized windows, as well as the Trash. For new user accounts Apple puts a default set of items in the Dock and Finder sidebar, but these can be customized.

The standard and perhaps intuitive method of adding items to these locations is to drag them there; however, it's not foolproof. If you inadvertently release your mouse before the cursor has reached the Dock or sidebar, then you chance copying or moving the … Read more

The Audiophiliac picks the best speakers under $650

I've said it many times: the very best audio is frighteningly expensive, and so are the world's best cars, cameras, clothing, boats, and so forth. The good news is there are really pretty spectacular finds at the other end of the audio rainbow. I love it when I come across an over-performing budget-priced speaker, and lately, I've found quite a few. Here's a newly revised list of standout designs.

Since this list covers a broad range of speaker types, there's no ranking order; each one is exceptional in its own right. I have spent time … Read more

While the Mac's keyboard and mouse ought to be enough for most purposes, having a dedicated gaming controller can give you the feel of playing with a gaming console.

Can expensive audio cables improve the sound of a hi-fi?

Some audiophiles swear that cables can make or break the sound of their hi-fis, while others poo-poo the idea and use the cheapest hardware store wires. The debates have raged for years, but the only way to really know for sure is to try a set of high-end cables in your system. When I sold hi-fis for a living, I convinced a lot of reluctant customers to buy a set of cables, with the promise I'd refund their money if they didn't hear a difference. The majority of them kept the cables; even some of the most skeptical … Read more
