@Rosa_Jackson I replied to your post in this thread on the Mac forum from which it appears you were well on the way to working out what you needed to do. From what you said there it seems you have the stand alone version of 1Password with data stored in, and sync'd through, Dropbox. There's no "account" involved in that case.
If you have any more problems I suggest you post in the other thread rather than this one as you'll probably get more help on the Mac forum with problems specifically relating to 1Password for Mac.
@Rosa_Jackson: It sounds like you have a 1Password license, not an account. You'd only have a 1Password account if you'd signed up for 1Password Families (or Teams). I've resent your license information via email, and you can follow the instructions there to install and register the app on your new Mac.
I hope this helps. Be sure to let us know if you have any other questions. We're here for you! :)
