launchd StartCalendarInterval behavior changed
Hello! I've been successfully using StartCalendarInterval in Launch[Agent|Daemon] *.plists for years. You know the deal: Mac is sleeping when CalendarInterval passes, then launchd runs the job when Mac is awoken. (This behavior is described at the bottom of an Apple doc from 2016 -- exactly how it worked before!) Recently, behavior has changed: with the computer asleep, when the date/time of the CalendarInterval passes, macOS runs the job! Even when "sleeping". However, it gets stranger: macOS will start a job when sleeping, but then suspend it in the middle. I wrote a timestamped log to check this behavior: I see job start, pause in the middle, then resume hours later when a user wakes the computer. This all makes me think that "sleep" on macOS in the past few years is now defined differently -- perhaps an Apple Silicon change? But I can't find documentation that covers this. Buried in a WWDC video, maybe? Has anyone else seen this change in launchctl calendar scheduled jobs?
