Is there HOME and END button on the MAC?

Of course not... but don't be panic

There are hotkeys to do the same

FUNCTION KEY + (Arrow Keys)

COMMAND KEY + (Arrow Keys)

HOME is equivalent to COMMAND + Left Arrow Key

END is equivalent to COMMAND + Right Arrow Key

Try yourself and figure out the difference...

Password protect my MAC BOOK

Because Mac OS X is based on Unix, the operating system has native support for a password-protected multiple-user environment. By default, you are required to set a single user with a password. If you have only one user created, your computer will not prompt for a user password when your computer starts. However, you may secure your computer with a password as follows:

• From the Apple menu, select System Preferences... .
• From the View menu, select Accounts.
• In Mac OS X 10.5.x, at the bottom of the left panel, click Login Options. In the right panel next to "Automatic login:", select Disabled from the pull-down menu. If the Login Options are grayed out, click the padlock icon in the bottom of the preference window and authenticate to your account.
• In Mac OS X 10.3.x and 10.4.x, at the bottom of the left panel, click Login Options, and in the right panel, uncheck Automatically log in as: . If the Login Options are grayed out, click the padlock icon in the bottom of the preference window and authenticate to your account.
• When starting your computer, you will have to authenticate to access your account. You may also log out of your computer without restarting. From the Apple menu, select Log out... .

Activate the ROOT USER in MAC

The root user, or superuser, is a special user account in Mac OS X that has read and write privileges throughout the file system. By default the root account is not active.

IMPORTANT: The root user can edit and delete important system files not available to normal users. To prevent damaging the system by moving or deleting important files, use extreme caution while working in the root account.

To enable the root user:

• Open Directory Utility, located in the Utilities folder in the Applications folder.
• Click the lock to make changes. You will need to enter an administrator name and password.
• Choose Edit > Enable Root User.
• Enter a secure password for the root user, then enter it again in the Verify field, and click OK.

The root user should be used only for specific administration or monitoring tasks. After completing a task as the root user, log out of Mac OS X and log back in using a normal user account.

To ensure the security and stability of your system, disable the root user when you are not using it.

For more information: Click on FINDER--> go to HELP--->type ROOT ---> it will guide you how to enable the root user
