In our last chapter, we learned how to backup your Macbook Pro with Time Machine in the event we have an issue while reformatting your Macbook Pro. This post will teach you how to make a MacOS Sierra boot drive. This post is in addition to the original instructions with the release of MacOS Sierra. You can always refer back to the table of contents to follow the entire process. If you booted from a USB disk, click “Continue” to advance to the installer.Note: This post is part of the the series: Reformat Macbook Pro to make brand new. If you booted from a functioning recovery partition, click the “Reinstall macOS” button. With your information wipe complete, you are now ready to reinstall macOS. If you choose three or five passes, you might want to leave this running overnight. If you opted to wipe your drive securely, this might take a while-30 minutes to an hour is not unreasonable for one pass. Just give your drive a name (I recommend “Macintosh HD”, just for consistency’s sake), then click “Erase” to start the overwriting process. You only need to write over a drive once to securely wipe it, but if you’re paranoid you can also wipe it three or five times.Ĭlick “OK” once you’ve decided, but remember: if your Mac has a solid state drive, you do not need to use these options. Now move the dial up, to randomly write data over your entire drive. You still need to wipe the drive, however, or your files will remain in place, so skip to the end of this step to do so.)

If you’re wiping a mechanical drive, click “Security Options” in the window that pops up. Click your primary drive, then click “Erase” If not you can find Disk Utility in the menu bar: click Utilities then Disk Utility.
To get started, click the Disk Utility option.ĭepending on how you started Recovery Mode, you may be presented with the option to start Disk Utility right away, as seen above. We’ve shown you how to securely wipe a hard drive with your Mac, and doing so in Recovery Mode isn’t really different from doing so within macOS. If you want a truly clean installation, however, you need to first wipe your hard drive. We recommend backing up files before you do this, just in case, but otherwise you’re ready for step three. Your user accounts and files will stay exactly where they are-only your operating system will be overwritten. If you want to re-install your operating system, but leave your files in place, you can skip this step.

You can access recovery without a partition using Network Recovery: hold Command+Shift+R while turning on your Mac and it will download the Recovery features for you. Failing that, you can create a bootable USB installer for macOS Sierra, and boot from that by holding “Option” while turning on your Mac.
If neither of these options work, don’t panic! You’ve got a couple of options yet.
