Fresh in on OSX, what do need to keep?

[jackrabbit]

Just preparing to do a fresh install on my mac as its not behaving. Doing a dootable back up too which i can copy nesasary folders from.

What folders do I need to keep? i.e. to keep my racks, instrument rack samples, retro pack samples and any other relevant stuff

Got the obvious covered like vst/au folders, main samples are on external drive anyway.

Any advice to make this task successful and smooth is welcome
