Hi,
I want to learn about macintosh... some one help me in learning it... send me tutorial please...

You might want to check out the information on the following site:

Using the Mac Operating System (http://www.macoptions.com/os85/)

Go to apple.com. They have info that can help. And it is more current than the previous link, unless you have an old mac.

Do you have a Mac? There is a tutorial built into the help menu.
