I want to change the way my Mac system is setup.

I currently have one large hard drive that has all the OS, applications and user data stored on it.

I would like to purchase a separate hard drive (preferably SSD), and have ONLY the Mac OS and applications installed on this. I will then use the current disk to store all user and applications data, files, media, etc.

My question is, how can I SAFELY migrate the Mac OS and Applications to the new drive but leave all other data on the current drive?

This question came from our site for professional and enthusiast programmers.

Ouch you might be out of luck, save important documents, reinstall on SSD, install applications? – Justin Meiners May 30 '13 at 21:24

Here is how I would do it:

  1. Backup the harddrive on a a backup drive (this could be done with Time Machine)
  2. Fresh reinstall of OSX on the SSD
  3. Follow this to setup the home on a different partition
  4. Use the migration assistant to grab accounts and App from the backup drive.

Because I'm lazy and coping/backing up takes for ever I would not wipe the hard drive and just rename /Users or try to use it as is directly actually :P and skipping step 4.1 (where 4.2 would be moving Apps to the SSD).
