Anyone else having trouble viewing passes under Mac OS 10.13 High Sierra ?

We encounter a lot of validation errors these days for files which still work reliably under any iOS version (and Wallet is known to be rather strict with validation… 😉).


Does anybody know of new pass requirements for 10.13 ?


The issue occurs mostly with freshly generated passes from a variety of sources; not just our own ones.


Any hint is highly appreciated.
