DESCRIPTION
caffeinate creates assertions to alter system sleep behavior. If no
assertion flags are specified, caffeinate creates an assertion to prevent
idle sleep. If a utility is specified, caffeinate creates the assertions
on the utility's behalf, and those assertions will persist for the
duration of the utility's execution. Otherwise, caffeinate creates the
assertions directly, and those assertions will persist until caffeinate
exits.
Installing software generally requires user permission. Replacing Hw can be done surreptitiously. At least that’s the strongman variant of the security argument.
