iSync question

I bought a mac on ebay but it does not have isync this is a program i really need i do not have the installation disc.

Does anyone know where I could acquire a copy?

I really need this app lol.

Thanks

I know this won't help you now, but I really wish people buying stuff on eBay would boycott computers that don't come with their disks.

iSync is only installed as part of the OS, so you need to ask the seller for the install disk, or return it saying the computer has an incompletre install of the OS - assuming that the version you have is even supposed to have iSync.

What version of OS X does it have, and does the software update work?

I think it is leopard.

i havent updated not enough room and dont want to delete anything.
