I’m getting rid of an old Apple Mac system, how do I make sure no-one can read my private information on it?

The most valuable thing on a computer is the data, so it’s important to wipe any system before disposing of it.

If you have an OS X or OS 9 system disk, you can completely wipe and “zero” the disk to make it extremely difficult for someone to recover any data from the old computer. Apple have detailed instructions on this at their How To Zero All Data On A Disk page.

Warning! Before following Apple’s instructions, make sure you have backed up all important and valuable data.
