To install software updates, you create a software update rollout job. You can view the rollout jobs and their status at Manage > Jobs and Tasks > System Jobs and Tasks > Software > Patch Management > Mac > Rollout Jobs.
If you want to install multiple updates at a time, Symantec recommends that you combine them in one rollout job rather than installing each update on an individual schedule. This ensures that package downloads and restarts are not interfering each other.
To install individual software updates
It is safe to run the rollout job on all supported Mac computers. When the rollout job runs, it checks if the update that you want to install is needed. If the update is not needed, the job does not download and does not install the update.
