Moving to a new Mac
A licence covers one Mac at a time, and moving it is yours to do. There is no support ticket in the way.1
Free the old activation
Open the store’s customer portal from your purchase email and release the
activation for the Mac you are leaving.Each activation is labelled with its
instance_name, which is Pomeroy
plus eight random characters, generated on that Mac. That label exists for
exactly this moment: so you can tell which activation is which without
Pomeroy having to know anything about your hardware.2
Activate on the new Mac
Install Pomeroy, open Settings → Licence, and paste the same key.
Nothing carries over automatically. Your toggles, grants and Messages
bookmark are per Mac, because they are macOS’s to give and yours to grant.
Expect to run through setup again, which takes a minute or two.
