Migration Assistant does nothing but migrate the crap from the previous version of OS X that a clean install is supposed to get rid of. Once you do a clean install, it’s like having a new (and much faster) Mac.

For those apps/sofware that I purchased on third-party websites, I just go to those sites and re-download them at no charge (assuming you still have you license information). Then install new versions of my apps (most of which have been updated to work best on El Capitan) from the Mac App Store. After wiping my hard drive of all of the garbage that it has collected since the last install of OS X, I just go into Time Machine and drag over my photos, movies, music, and documents to their folders in Finder. I’ve never lost a single piece of data after a clean install.

Using Migration Assistant undermines the entire process of a “clean install.” It’s the worst way to install a new version of OS X because it simply restores (i.e., “migrates”) all of the crap that has built up on your hard drive from the previous version of OS X on you Mac, especially in the User Library (e.g., vast amount of cache garbage, old, corrupt. Now you’re ready to manually move your files and data back to the Mac, or start as new with nothing on the Mac, whatever works for you. No files, no data, nothing will be on the Mac except for what comes with OS X El Capitan, that is what a clean install is for. When finished, OS X El Capitan will boot into a brand new clean install, running through the initial OS X setup process on the Mac as if the Mac was brand new.

How to Clean Install OS X El Capitan & Start Fresh If you don’t know what you’re doing with a clean install, and you have not made backups, don’t try this, you will lose data.
