Until Paul mentioned his own problems, I glossed over these failures because I was satisfied that my production built versions, linked against the 10.13 SDK, were “working fine.” But Paul’s report got me thinking: was it possible there is some unspoken contract here, whereby linking against the 10.14 SDK opens up my app to additional privacy related requirements?<\/p>\n

I tapped into Xcode’s Info.plist editor for FastScripts, added a new field, and typed “Privacy” on a hunch, because I’ve come to realize that Apple prefixes the plain-English description for most, if not all, of their “usage explanation” Info.plist fields with this word[…]<\/p>\n

Aha, that first one looks promising. You can right-click on an Info.plist string in Xcode to “Show Raw Keys\/Values”, and doing so reveals that the Info.plist key in question is “NSAppleEventsUsageDescription”. After adding the key to my app, I built and run again, and running the same script as above now yields the expected authorization pane[…]<\/p>\n<\/blockquote>\n\n

I believe the WWDC session<\/a> said that the other usage descriptions are required if you build with the macOS 10.14 SDK. NSAppleEventsUsageDescription<\/code> was not added until Beta 7<\/a>, though. It’s kind of odd that this key just has a single string value, since an app might want to send events to any number of different apps, for different reasons. Everything needs to go in that one string.<\/p>\n\n

And it’s too bad there’s no corresponding usage description or prompt for Full Disk Access. Your app just gets a permissions error, and you have to explain to the user how to enable access in System Preferences.<\/p>\n\n
