I now have Yosemite on my new MacBook Pro laptop but can not figure how to install on it. I have my license number.

All you should need to do is download a copy of 1Password 3 from the Legacy section of our AgileBits Download page and move the 1Password application into your /Applications/ folder, unless I'm misunderstanding and the question is about how to migrate your vault from one Mac to another?
OK, I think I downloaded it successfully. But how do I get all my PWs from the old laptop onto the new one? Do I have to use iCloud? If so, how?
@cammanned: Sorry for the confusion! 1Password 3 predates even the existence of iCloud, so that option isn't available there. However, you can use Dropbox to sync your 1Password data over, or — more simply — copy the .agilekeychain to your new Mac manually if you're not planing on using 1Password on the old one any longer:
When you set up 1Password on the new Mac, just tell it you're an existing user, and then point it to the .agilekeychain vault you copied over. I hope this helps!
