Reset to factory settings for development?

[GameViewPoint]

I want to get a used iMac to develop games on, I was wondering, do I need to reset it back to factory settings to do that? I'm thinking when you sign up to the Apple developer program it uses the settings that are already on the machine? i.e the previous owners? So I need to reset it to put my own details into it?

Thanks for any advice.

Yes.
When you buy a used Mac it is always a good idea, to do a clean install.

To create a Clean Install (formerly known as Erase & Install) of Mac OS X 10.6 Snow Leopard (the 29 USD Upgrade DVD is a fully working retail version of Mac OS X and does not need a prior installation of Mac OS X on the Mac), follow one of the following guides:

• Short version: Clean Install of OS X 10.6 Snow Leopard
• Long version: Mac OS X v10.6 Snow Leopard: How to Erase and Install

That's what I suspected, I might be getting a Lion OS version though, how do I do the "clean install" option for Lion?

You get a Mac, that originally came with Lion or a Mac, that has been updated to Lion?
