How to Quickly Wipe a Mac without OS X System Disk (or CD)

You’ve got a new Mac or PC, and now you are planning to recycle your old Mac. You are told that one of the critical steps before selling a Mac is to wipe the hard drive clean. So you try to look for the OS X disk (or CD) to reinstall your old Mac OS X, but in vain.

Is there a way to wipe a Mac without the system disc or CD? You wondered.

Well, the thing is Apple has stopped distributing Mac OS X on DVD disk a long time ago, and you can barely find a Mac that comes with the optical drive to load a CD/DVD — according to a CNET report in 2013, Apple’s plan to wipe out disc drives is nearly complete.

But, that doesn’t mean there isn’t a way to erase your Mac hard drive. In this post, I’m going to show you how to get it done effortlessly.

STOP — before you start

The following guide aims to completely wipe your Mac hard drive. That means once done, all the data stored on that drive or partition are gone for good. Therefore, I highly recommend you triple check and make sure those important files and folders have been transferred to your new computer or have been backed up to an external hard drive. Take the steps below only after you’ve done so. You’ve been warned.

Things you’ll need

  • Stellar Wipe software (requires to download first)
  • Your old Mac
  • Internet connection

A tutorial to erase Macintosh hard drive without system disk

Step 1: Free download Stellar Wipe and install the application on your Mac machine from which you want to securely erase its hard drive. Launch the app, select the “Drive Wipe” option. This option ensures complete and permanent removal of all the data from the entire hard drive or partition.

Step 2: Click the “Continue” button. Now select the Macintosh partitions to proceed. Note: if you only have one main boot partition, you can’t use this app to perform the task. Click “Continue” to proceed.

Step 3: Now you’ll come to an interface with a list of wiping algorithms. You don’t need to go deep. Usually, a few zeroes are enough to wipe everything. If you are paranoid, select the highest algorithm which is beyond recovery for sure.

Step 4: Start the wiping process. Wait for a few minutes before it is complete. Now you have successfully erased a Mac hard disk without the CD. Done!
