Hi! I'm debugging an XPC service with the ultimate aim to self-update one of my apps. The app itself is sandboxed, the service is not (which is OK as it's Developer-ID signed). So, the service runs well, downloads and installs the update if necessary, then launches the new version while quitting the old. All this works well, too, and I plan to release it soon, but... However, I see two strange errors in the Console log: 1) on my first call to the XPC service: ... com.apple.xpc.launchd[1]: (com.apple.xpc.launchd.domain.pid.<appName>.45747) Ignoring lax activation attempt for unsupported domain: <serviceBundleId> 2) when launching the updated app: ... com.apple.xpc.launchd[1]: (com.apple.xpc.launchd.domain.pid.(premature birth).45747) Could not resolve origin of domain. XPC services in this domain's bundle will not be bootstrapped: error = 3: No such process, taint = (untainted) This happens regardless of the value of "JoinExistingSession" in the XPC service's Info.plist. Note that both PIDs are the same, too! Any hints welcomed.
