@bens1password: A 1Password license is only valid for specific version purchased. So, if I understand what you're proposing, the answer is no: you cannot use a 1Password for Windows version 4 license with 1Password for Mac version 6. You can, however, use the app in "read only" mode without a license.
However, you may want to consider a 1Password.com membership, since it gives you access to all of the apps, the web interface, and does away with license management and sync configuration altogether — you simply login to your account to authorize a device and access your data. You can try it for free for 30 days to take advantage of all of its benefits.
Anyway, I hope this helps. Be sure to let me know if you have any other questions!
Thanks, Brenty, that's helpful.
