Normally when you install a new version of macOS, you just install it over the previous version. It’s quick, easy and means we can be back up and running in no time, with all your apps and data ready to use. Your data remains but your software and file junk remains as well.

That’s why, sometimes, it makes more sense to run a clean install. Whether it’s because your Mac has accumulated so many junk files that it’s performance is badly affected or because you’re passing your Mac onto someone else and want to make sure all your data is removed. Or maybe you just want that fresh out of the box Mac experience again. Whatever your reasons, here is how to clean install macOS High Sierra.

How to prepare your Mac for the clean install

Before you do anything, check that your Mac is able to run Apple's new operating system.

To complete the clean install procedure described below, you'll need:

macOS High Sierra Installer,available from the Mac App Store.
a 16GB or larger USB flash drive
Notice: USB drive is needed for a clean install on your Mac’s startup drive. If you plan to clean install macOS on a non-startup drive, you don't need it.
go for a system cleanup and backup your data - this will allow you to easily return your Mac to the condition it was in before you installed macOS.
and an hour or two to spare.

Choose the right way to clean install macOS High Sierra

Before you proceed, you need to make a choice how to run a clean install. If you only have one drive and it’s not partitioned and this is where you have all your files and your OS, your choice is to clean install on the startup drive. This way entails one important fact: all your files and data will be deleted during the process.

If you have another drive or volume other than your startup drive, use the second way which is clean installing on a non-startup drive. It’s a more lenient and less intrusive way because your Mac doesn’t get wiped clean, only your system.

If you don’t know which one you have, go with the first option, startup drive.
