Q: How do I dowload or upload a web site designed in iweb to another Mac

The latest and final version of iWeb is iWeb 09 or version 3.

To move the iWeb created site you need to find your domain.sites file and move it to the other computer and then double click on the domain file and iWeb should open it.

The domain.sites files can be found in your User Library/Application Support/iWeb/domain.sites.  Locate this and it is your User Library and NOT your system Library and find the domain file and then transfer it - you can do this with a usb memory stick or an external hard drive or you could even e-mail it to yourself - but you need to transfer this is put it in the same place on the other computer and then double click it and iWeb should open it.

If you have iWeb 09 on the other Mac and the domain was created with iWeb 08 for example, then you should have no problem - remember that iWeb is not backward compatible though, so once opened with iWeb 09 you cannot again open that domain file with iWeb 08.
