A friend is going to get a Mac and now has an Ipad synched to a Windows computer. I know how to restore the Ipad but what I don't know is can you move the Apps you purchased on the Windows to a Mac computer?
To Apple, you are your iTunes account, not your computer. So just plug the iPad into the new computer, log on to iTunes with your account that has the apps, then wait as iTunes downloads your apps to your computer and your iPad.
