Codebook synch iPhone to new MacBook Pro

I have replaced an old MacBook Pro with a new one. Previously synched the iPhone with old MacBook Pro on wifi. Now ant to synch to Codebook on new MacBook. Do I delete the Synch Key on the new MacBook?

Hi @Hugh, thanks for using Codebook!

Do I delete the Synch Key on the new MacBook?

I’m not sure I understand why you’d need to do that: when you ran Codebook for the first time on your new Mac, did it prompt you for the Sync Key you were already using on your iPhone and old MacBook?

Another way to put it: did you provide the Sync Key you were already using to your new MacBook using your iPhone during setup, or did you allow Codebook on the new MacBook to create a new one?

Sorry to answer a question with another question, but I don’t want to give you the wrong advice. Thanks!
