On freshly set Mac, or in VM, when there is NO internet access, xcrun simctl boot <UDID> fails to boot any simulator with the error: Unable to boot device because we cannot determine the runtime bundle xcrun simctl list devices displays all created simulators with error message: runtime profile not found using "System" match policy As soon as you connect machine/VM to the internet, and start Xcode.app GUI, everything starts to work. Internet can be disconnected afterwards. This is very bad for CI automation. Feedback filled https://feedbackassistant.apple.com/feedback/13098070
