I have a couple of Macs and I would like to create some kind of script that I can use to:

1. Easily setup a new Mac after a reinstall
2. Update settings to consistent values (so if I decide to change some preferences on Mac A, I can run the script on Mac B to get it to match)

I'd be happy if I could use this script to customize:

• System Preferences
• Finder Preferences

I would prefer a method where I can use a script or config file to specifically set certain settings I choose to certain values. I don't really want something that will import/export ALL settings indiscriminately.

I also don't want some complicated IT management solution, since this is really just for me.
