Following that, the app’s frameworks and any other components are scanned for malware, according to iOS Platform Policy. LaunchServices sends the Open App initial AppleEvent to the app, and the ProcessManager () starts the app’s stopped process. Reset CPU monitoring limits to defaults.

RunningBoard then registers the launch request, executes it, and starts tracking the process.ġ.060032 Creating and launching job for: applicationġ.072092 Now tracking process: įrom here on, a long series of assertions are handled by RunningBoard, to change its management of the app as launch progresses. LaunchServices announces the app will be launched through RunningBoard, and sets the flag to disable pointer authentication for that launch. Wrapped iOS/iPadOS apps aren’t retained indefinitely, but periodically cleaned up.ġ.055056 LAUNCH: translocate to from The translocation path ensures the app’s name and path remain fixed. In macOS, the user can run apps from (almost) any path, such as the Desktop, and can rename apps.The path to the translocation folder guarantees that. iOS/iPadOS apps may expect to be run from a path which doesn’t contain whitespaces.This isn’t for security purposes (as is the case when first running macOS apps with a quarantine flag set), but to work around two limitations: All iOS/iPadOS apps run in macOS are translocated. LaunchServices prepares to translocate the app from its current location to a hidden folder, in which it’s wrapped with a couple of Property Lists and run. Next, a mobile service named MIS () checks the app bundle against a blacklist, and validates it, which System Security Policy declares as forming a valid App Wrapper.ġ.054198 MIS validation result: 0ġ.054230 appWrapperPolicyResult:, AWPolicyResult: 1,1,0 LaunchServices, which handles Finder interaction such as the launching of apps, recognises that this is an iOS app, and needs to be launched using CoreServicesUIAgent.

Giving the start time for these events at just after 1 second. I provide short snippets from the log to support each step, with times being given in decimal seconds.Īs this iOS app is being launched in the Finder, the double-click is marked by two pairs of activities recording that This article dives considerably deeper, looking in detail at how macOS launches an example iOS app. In my previous explorations of how M1 Macs run iOS and iPadOS apps, I discovered that they are always run in translocation, and that they engage in elaborate relationships with RunningBoard and other new sub-systems in macOS.
