Enable root login on Mac OS X
I have a second hard drive in my MacBook Pro that stores the user’s files. To enable state safe manipulation of those data, I like to log as root. This way, I ensure that none of those files will be modified during operation (copy, move, …). Here’s how to enable root login on Snow Leopard: From the menu, select System Preferences ; From the System section, select the Accounts tool ; Select the Options option and click the Join button ; Click the Open Directory Utility button ; Click on the lock and enter the administrator password ; In the Edit menu, select the Enable Root User command ; Fill-in the root password and click OK.
