When you double-click a file it will open in the default application, which is fine for most situations. Often, each file format corresponds to a single application. Word documents open in Microsoft Word, MP3s open in iTunes and movies open in Quicktime Player. But there are times when you might want a file to open in a different application. For example, you might want a image to open in Photoshop rather than Preview, or a Word document in TextEdit instead of Microsoft Word. In this situation, you have a few options.
Firstly, if the application is in the Dock, you can simply drag the file onto its icon in the Dock. Alternatively you can open up the application first, and choose “Open” form the File Menu. A third method is to use the “Open With” menu. You will find this by right-clicking (Control-clicking) on the file and looking near the top of the contextual menu. Within the Open With submenu you will find every application that can open the file, as well as an “Other” option.
When you use the Open With menu, it is a “this time only” thing. Next time you double-click on the file, it will open with the default application again. To change the default application, bring up the menu as before, but hold down the Option key before choosing the application. The menu should change to “Always Open With”.
When you use the Always Open With menu, it is a “this file only” thing. To apply a new default application to all files of that format, you can use the Get Info window located in the File Menu. In the Open With section, set the new application and click the “Change All” button.
To reset all of your files to open with the original default application, you need to delete a certain file. Go to your user folder, and navigate into the Library folder then into the Preferences folder. Find the com.apple.LaunchServices.plist file, and drag it to the Trash. Alternatively, drag it to the Desktop if you think you might change your mind and want to put it back later.
Over time, you may find that the Open With menu gets cluttered with duplicates, older versions or applications you thought you deleted long ago. To get rid of these, you need to use Terminal. Open up Terminal (from Applications/Utilities) and paste the following line:
/System/Library/Frameworks/ApplicationServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
Press return and your Open With menu should have been cleaned up to only include the most current applications.

Wireless networks are helpful because they let you use your computer and connect to the Internet anywhere in your home or office. However, most wireless networks use a wireless router, which can be expensive. If you have more than one computer, you can set up a wireless network without buying a wireless router and save yourself some money.

The latest version of the Mac OS X known as Tiger brings Jabber support to iChat which indirectly supports other messaging protocols like MSN, ICQ, AIM and IRC.
In nearly every case, you only have to do one thing when you no longer want to run a program on your Mac OS X computer: You drag it to the trash.When you’ve decided you no longer want to keep a program, you locate it and drag it to the trash can. There’s nothing to uninstall. You simply get rid of it.
If you’re not sure where any of your programs are? Apple took pity on those of us who are too busy to locate anything in all the hiding places on our hard drives, so it added a feature that makes removing programs absurdly easy. You simply Ctrl-Click (or right click) on the alias for an application — on the icon in the dock, for example — and click “Show Original.” A window will open showing the original application. Should you drag that to the trash now? Maybe. And then again maybe not. There are two basic kinds of programs for OS X. One kind is old-fashioned, consisting of a program file (or “application,” as Apple calls it) and possibly a few other files. When you want to get rid of a program of this kind, you should get rid of all its files.
The other kind represents a new program-packaging idea that surfaced with OS X. Apple liked the idea of packaging software so much that its engineers even called it a “package.” To you and to me, a package looks like a single file. You see one icon. A good example of a package is Safari, the Apple Web browser. Look in the Applications folder and you’ll see a single Safari icon. That’s the Safari package. There are, incredibly, more than 150 separate files inside the Safari package, but you’d never know it from looking at the single icon.
In most ways, a package acts like a file. The operating system hides the “folderness” of a package to discourage casual users from peeking inside and messing things up. But here’s how to sneak inside a package if you want to see what’s there: Ctrl-click (or right click) on the package icon and click “Show Package Contents.”
So before you drag a program to the trash, you have to make sure you’re dragging the right thing. If it’s a package, you’re free to schlep it right into the trash. But if the program you want to get rid of is the old, unpackaged kind, you should drag it and any associated files into the trash. You might see the application file (or icon) along with documentation such as a “Read Me” text, for example. Your task is made really easy if the program you want to get rid of is located in its own folder. In that case, drag the folder into the trash.
Don’t empty the trash right away. Wait until you are sure you don’t need the program.
MacBook and MacBook Pro are the new powerful laptops from Apple that use Intel processors instead of PowerPC ones. When you buy a MacBook you get OS X Tiger pre-installed on it. But, you can still install GNU/Linux on this beautiful box. If you want to know how, read on the article.
