This optional key is used as a hint to <literal>launchctl(1)</literal> that it should not submit this job to launchd when
|
|
loading a job or jobs. The value of this key does NOT reflect the current state of the job on the running
|
|
system. If you wish to know whether a job is loaded in launchd, reading this key from a configuration
|
|
file yourself is not a sufficient test. You should query launchd for the presence of the job using
|
|
the <literal>launchctl(1)</literal> list subcommand or use the ServiceManagement framework's
|
|
<literal>SMJobCopyDictionary()</literal> method.
|
|
|
|
Note that as of Mac OS X v10.6, this key's value in a configuration file conveys a default value, which
|
|
is changed with the [-w] option of the <literal>launchctl(1)</literal> load and unload subcommands. These subcommands no
|
|
longer modify the configuration file, so the value displayed in the configuration file is not necessarily
|
|
the value that <literal>launchctl(1)</literal> will apply. See <literal>launchctl(1)</literal> for more information.
|
|
|
|
Please also be mindful that you should only use this key if the provided on-demand and KeepAlive criteria
|
|
are insufficient to describe the conditions under which your job needs to run. The cost to have a
|
|
job loaded in launchd is negligible, so there is no harm in loading a job which only runs once or very
|
|
rarely.

This optional key describes, at a high level, the intended purpose of the job. The system will apply

resource limits to the job, throttling its CPU usage and I/O bandwidth. The following are valid values:
|

|
|
Background
|
|
Background jobs are generally processes that do work that was not directly requested by the user.
|
|
The resource limits applied to Background jobs are intended to prevent them from disrupting the
|
|
user experience.
|
|
|
|
Standard
|
|
Standard jobs are equivalent to no ProcessType being set.
|
|
|
|
Adaptive
|
|
Adaptive jobs move between the Background and Interactive classifications based on activity over
|
|
XPC connections. See <literal>xpc_transaction_begin(3)</literal> for details.
|
|
|
|
Interactive
|
|
Interactive jobs run with the same resource limitations as apps, that is to say, none. Interactive
|
|
jobs are critical to maintaining a responsive user experience, and this key should only be

used if an app's ability to be responsive depends on it, and cannot be made Adaptive.
