;; NOTE:
;; This profile is only used on macOS
;; As of July 2024, systemstatusd uses the temporary-sandbox profile on iOS (and presumably all other embedded OSes)
;; Many properties which are controlled by entitlements on iOS et al are instead part of the sandbox profile on macOS
;; When editing entitlements or this profile, please consider whether those changes are relevant on other platforms
