It’s simple to delete unwanted files using Mac OS X Leopard: Just drag the files onto the Trash icon in the Dock (or select them and type Command-Delete), then choose Empty Trash in the Finder menu (or type Command-Shift-Delete). Alternately, you can double-click on the Trash icon to open it, then click on the Empty button.
Emptying the Trash in this manner clears room on your Mac for other files. But the data hasn’t actually been removed from your computer — the space occupied by these files is simply available to be overwritten by new information. Until this happens, it may be possible for someone to use data recovery software to restore your “deleted” files. And if this information is sensitive or confidential, it could potentially end up in the wrong hands.
That’s why Mac OS X Leopard provides another option for deleting data: the Secure Empty Trash command. Meant for those occasions when you want to permanently and immediately delete files, Secure Empty Trash overwrites your data with digital gibberish, ensuring that your deleted data is gone for good. It may take a few moments longer, but it’s a good choice for deleting data you’re sure you don’t need — and don’t want anyone else to see.
To delete your Trash securely, go to the Finder menu and select Secure Empty Trash. A pop-up will ask you to confirm that you want to permanently erase the items in the Trash. Click OK, and these files will be gone forever.
It’s easy to work with Microsoft Word files on your Mac, even if you don’t have Microsoft Word installed on your computer.
TextEdit, your Mac’s built-in word processing program, can open MS Word files (which are often distinguished by a “.doc” or “.docx” suffix). Simply double-click the document icon. It will automatically open in TextEdit if that’s the only word-processing program on your computer. If you have several, you can specify which program to use by Control-clicking on the file icon (or right-clicking if you have a two-button mouse) and selecting your desired program.
Now you can edit the file just like any other document. However, if you want to share your file with MS Word users, be sure to save your work in Word format. Here’s how.
From the File menu, choose Save As… or type Command-Shift-s. Click-hold on the File Format tab and choose one of the Word formats. Press Save.
If you own iWork ’08, you can use similar techniques in Pages, Apple’s advanced word processor. But instead of using the Save As… command, select Export from the File menu. Choose the Word option and press Next.
Finally, navigate to the destination where you’d like to save the document, and press Export.

If you have that annoying window telling you to validate your window OS, here you have a simple way to disappear that window.
- Go to c:/Windows/System32 folder.
- Find these two files: WgaLogon.dll and WgaTray.exe
- Rename both to: WgaLogon.dll.bak and WgaTray.exe.bak
- A windows alert you about it just say continue.
- Reset you computer.
- Then go to Windows Update Configuration and tell it to “Notify me but don’t automatically download and install them”.
- Next time windows try to install it just say no or check it and hide if you are in Windows Vista.

I live in San Luis Potosi, Mexico and here we do not have the iTunes music service so I can not buy music from iTunes store. So what I do to have more ringtones on my iPhone is really simple and best of all GRATIS! (Free).
Step 1.
- Convert your music from your CD, mp3 or whatever to AAC.
- This will give you an .m4a file.
Step 2.
- Rename the .m4a file to .m4r file
Step 3.
- Using iPhoneBrowser upload the new ringtone to your iPhone.
iPhoneBrowser is a free software that helps you navigate your iPhone files the easy way. You can download it from here.
