You restored from your time machine backup and your apple pay needs to reset.
But it can’t! As a result, you end up in an infinite loop of requests for elevated permissions.
Apple Pay is already configured on this disk for another Mac.
The solution (from Apple) after several levels of elevation to senior engineers is reported to be:
reinstall osx and don’t use a time machine backup
Unfortunately I just don’t have the time or inclination to do that, particularly when Time Machine exists to prevent that necessity!
Here’s how to reset your apple pay on your Mac. I’m running High Sierra, it should work for Sierra too.
The commands below do the following:
- Change to the private database directory.
- Move the applepay folder into another folder (you could move it back later, that way).
- Kill the seld (secure enclave) daemon process.
- Kill the nfc daemon that apple pay uses.
cd /private/var/db sudo mv -i applepay applepay.old sudo pkill seld sudo pkill nfcd
No restart needed, go back to System preferences -> Wallet and you should be able to set it up now.
