Hi all,

We are getting a few reports from a couple of our more adventurous customers who are running a beta version of 10.13.2, saying that our app doesn’t launch (the App is available on the App Store and launches fine on 10.13.1).

From the description, it seems it fails extremely early in the launch process, and gives up long before it executes main(). We are trying to get logs and so on to see if there’s anything there. Officially we don’t support unreleased OS versions, and we’re not running this ourselves, so it’s not easy to quickly check out. However if there’s something changed about launching, we want to be ready for it.

Has anyone else seen this behaviour? If so, what’s the cause and should we do anything about it?
