I'm migrating to a new MacBook. Do I have to spend another $64.99 to get the app on my new laptop?

Hey @Brian_MFS! Nope, your single-user license will work on any computers you own.

Information about adding your license to 1Password can be found here: Add your license.

And before you migrate, you may want to double-check and make sure iCloud or Dropbox syncing is enabled, so you'll have access to your saved items on your new MacBook. :)
