The Unarchiver

The Unarchiver is a much more capable replacement for "BOMArchiveHelper.app", the built-in archive unpacker program in Mac OS X. The Unarchiver is designed to handle many more formats than BOMArchiveHelper, and to better fit in with the design of the Finder. It can also handle filenames in foreign character sets, created with non-English versions of other operating systems. I personally find it useful for opening Japanese archives, but it should handle many other languages just as well.

It is very simple to use and install - simply copy it into your Applications folder or whereever you prefer, and then set archive filetypes to open using it. This can either be done the usual way, or by double-clicking the icon to show The Unarchiver's preferences.

Supported file formats include Zip, Tar-GZip, Tar-BZip2, Rar, 7-zip, LhA, StuffIt and many other more or less obscure formats

Introduction to Mac OS X

Ever wonder why people get so attached to their Mac? Think Mac OS X. At the core of every Mac, Mac OS X is what makes your digital life more simple, more productive, and just plain fun.

It’s easy.

Mac OS X is a celebration of simplicity and common sense. No complicated menus. No obscure commands. Most tasks can be accomplished with just a click or two. And if you ever need guidance, there’s a built-in help system to light the way. Oh, one more thing: Mac OS X is simply breathtaking — and easy to personalize with desktop pictures and screen savers.

It’s advanced.

Making amazing things simple takes seriously advanced technology. Mac OS X is built on a rock-solid UNIX foundation, delivers true 64-bit performance, and incorporates industry-leading animated graphics. The beauty is, you don’t have to know what one word of that means — just start up your Mac and enjoy it.

It’s amazing.

More than an operating system, Mac OS X is a collection of very cool applications. It comes with everything you need to surf the web, send beautifully designed email, video chat, and organize your personal information.

It’s secure.

In a world where PCs constantly do battle with viruses and malware, Mac OS X is a sea of tranquility. Just go about your business and Mac OS X minds the fortress. Your documents are safe even if you share your Mac with others, and you can keep your kids safe by using a rich set of parental controls.

It’s compatible.

It’s a big world out there, and Mac OS X fits in perfectly. It runs Microsoft Office. It has built-in drivers for cameras, printers, and external drives. It plugs right into a PC network. And in case there’s a PC application you can’t live without, Mac computers can even run Windows. Mac OS X is compatible with everything — most of all, you.
