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

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

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

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

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 platform has not been noted for catering to hard-core gamers, there are still many popular gaming titles and gaming accessories available for the Mac OS. If you own a Mac and have a few games you would like to try, then you might also be interested in getting a gaming controller or two up and running with your system. 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.

Of the game controllers available for home computers, … Read more

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

The default size of the mouse pointers in OS X should allow them to be viewable in most situations, but there could be some instances in which the cursor can be difficult to locate. For example, if you need to dim your screen, it might be difficult to find the pointer; and sometimes, optional pointers -- such as those for text input or crosshairs -- can become lost among the textures of images on the screen.

This might be especially true when using projectors and large-format displays, where the relatively small cursor can be difficult to locate.

While you can … Read more

The standard F1 through F12 function keys in OS X by default are set to change a number of common system settings, including audio volume, backlight and brightness levels, and media player controls. Convenient as this is, sometimes their default behaviors can be intrusive or too crude for your needs.

For example, if your system is connected to an external amplifier that is set to a high volume, then the increments changed by the volume function keys may be too crude for your needs, and the corresponding audio indicator pop may be unpleasantly loud and intrusive, especially if you are … Read more
