I need space!

First of all, let me disabuse you of a misconception: Adobe all upgrades are FULL installers.  If you buy upgrades or new versions does not have one iota of difference.  Upgrade installation programs do not need to find a previous version installed, they invite you just for the old serial number as well as the old one and they are not based on the old version in the slightest.

Second, the time to uninstall an earlier version is BEFORE upgrading to a newer version.  If not, uninstall older versions will mess up with your new installation.  There are a gazillion of the files that are named the same and in the same locations as the other.

Your best bet now is to uninstall ALL versions of Photoshop, you have it installed, including the newest one, one by one, and then run the Adobe CS clean-up tool, and then run repair permissions of the Apple desktop utility and finally reinstall the latest version.

The other alternative, if your boot HD is quite large (very questionable in the case of a laptop as a Mac Book), is to leave all the versions on this subject.

Your choice.
