In fact, Lion, Mountain Lion, and Mavericks automatically detect some incompatible programs and system add-ons the first time you log in, as explained in my main installation article. But the Snow Leopard installer and Setup/Migration Assistant were pretty good about not transferring incompatible software, and subsequent OS X installers have gotten even better. OK, so you can, but should you? Prior to Snow Leopard (OS X 10.6), I generally recommended a clean install.

Should you perform a clean install of Mavericks?
(In this situation, the more apps you’ve purchased through the Mac App Store, the better-you just launch the Mac App Store app and click a few buttons to automatically reinstall everything you’ve purchased.) If you want a truly clean start, you’ll instead need to manually copy your personal data from your backup to your new Mavericks installation, and then reinstall all of your software. Once you’ve done this, if you want to use Setup/Migration Assistant to restore data from your backup, proceed with Step 8. Specifically, scroll down to the section called “The brute-force method” and perform Steps 1 through 7, substituting “Mountain Lion,” “Lion,” or “Snow Leopard” for “Leopard” the result is a clean install.

In fact, you can use the instructions in my article on how to install Mavericks over Leopard.
So if you first back up your existing Mountain Lion, Lion, or Snow Leopard (OS X 10.6) installation and all your files-I recommend creating a bootable clone using SuperDuper or Carbon Copy Cloner-you can then boot from a bootable installer drive, erase your Mac’s normal startup drive, and install Mavericks on it. As explained in my main article on installing Mavericks, the installer will let you install the new OS on a blank drive. With the debut of Mavericks, as with Mountain Lion and Lion, many Mac users are asking two related questions: (1) Can you perform a clean install of Mavericks? (2) Should you? Here’s my take on each of these questions, which is essentially the same as with Mountain Lion last year.Ĭan you perform a clean install of Mavericks?įirst, the technical question: Given that the OS X 10.9 installer doesn’t include an official clean-install option, is it possible to perform such an installation? The simple answer is yes. Instead of using a bootable installation DVD, you download the latest OS X installer to your Mac and install the new OS from the same drive. This feature was eliminated in the Snow Leopard OS X 10.6 installer.)īut a new download-and-install procedure debuted with Lion (OS X 10.7) and has continued through Mavericks (OS X 10.9).

(The Mac OS X 10.2 installer debuted an Archive And Install option, which preserved your original 10.1-or problematic 10.2-installation in a special folder while installing a completely new, fresh copy of Mac OS X 10.2. For this reason, many people performed a “clean install”: wiping your hard drive (after backing it up, of course), installing the latest version of OS X, and then either using Setup/Migration Assistant to restore your applications and data, or manually reinstalling programs and copying over your data. It used to be that if you upgraded to a major new version of OS X, installing over an existing OS X installation-for example, installing 10.3 over 10.2-entailed some degree of risk, as existing applications, add-ons, and support files could conflict with the new OS.
