I have a purchased copy of Leopard and want to install it on my computer and my parent's. Is it possible? Will it cause problem when we're both on the same network? Any problems updating?

Thanks!

Hmmmmmmmmmmmmm.

I could say something, like it will cause all your files to be deleted. That would deter you.

The answer is that you are supposed to buy a copy of Leopard for each computer you install it on.

I think this question needs to be a sticky: it gets asked SO often.

Technically: Yes.

Legally? No.

Apple doesn't make us go through activation hoops like Microsoft does with Windows; let's not give Apple a reason to do so.

Yep - Apple trust people, and does not make their software with all the spyware activation crap. Don't abuse that.

This is the reason for Leopard Family Pack existence. This 5-license package in the US costs about the same as a single Leopard license in the UK, so it's a bargain IMO.
