These questions and answers will help you strengthen your technical skills, prepare for the new job test and quickly revise the concepts.
In OS X, you can run a background job on a timed schedule in two ways: launchd
jobs and cron
jobs. (Older approaches, such as at
jobs and periodic
jobs are deprecated and should not be used.) This section explains these methods briefly and provides links to manual pages that provide additional details.
Timed Jobs Using launchd
The preferred way to add a timed job is to use launchd
. Each launchd
job is described by a separate file. This means that you can manage launchd
timed jobs by simply adding or removing a file.
To create a launchd
timed job, you should create a configuration property list file similar to those described in Creating a launchd Property List File except that you specify a StartCalendarInterval
key containing a dictionary of time values.
For example, the following property list runs the program happybirthday
at midnight every time July 11 falls on a Sunday.

For more information on these values, see the manual page for launchd.plist
.
Timed Jobs Using cron
Note: Although it is still supported, cron
is not a recommended solution. It has been deprecated in favor of launchd
.
Systemwide cron
jobs can be installed by modifying /etc/crontab
. Per-user cron
jobs can be installed using the crontab
tool. The format of these crontab
files is described in the man page for the crontab
file format.
Because installing cron
jobs requires modifying a shared resource (the crontab
file), you should not programmatically add a cron
job.
Effects of Sleeping and Powering Off
If the system is turned off or asleep, cron
jobs do not execute; they will not run until the next designated time occurs.
If you schedule a launchd
job by setting the StartCalendarInterval
key and the computer is asleep when the job should have run, your job will run when the computer wakes up. However, if the machine is off when the job should have run, the job does not execute until the next designated time occurs.
All other launchd
jobs are skipped when the computer is turned off or asleep; they will not run until the next designated time occurs.
Consequently, if the computer is always off at the job’s scheduled time, both cron
jobs and launchd
jobs never run. For example, if you always turn your computer off at night, a job scheduled to run at 1 A.M. will never be run.

1. Provision a macOS 10.12 Sierra node.
- To run iOS/Mac builds, you will first need to provision a macOS 10.12 Sierra machine in a private or public cloud. At this time, Shippable does not allow you to dynamically provision Mac nodes and we will be soon launching this functionality.The minimum requirements for the node are documented here.
- Only runSh jobs are supported for iOS/Mac at this time.
2. Purchase the Mac OS SKU
- Go to your subscription billing plan by following the instructions documented here.
- You can purchase the Mac OS SKU only if your subscription has been upgraded to the latest release. If you subscription has been upgraded, the billing plan page will look like this.

3. Configure Node pools
- After you create the Mac SKU, a default Node Pool is created and all the purchased nodes are assigned to the default Node Pool.
- You can however create more Node pools if you want and change the allocation of nodes amongst your node pools. Thereafteryou can assign your runSh jobs to a specific Node pool.
4. Initialize your BYON node
- Navigate to the Nodes setting page for your subscription by following the steps documented here.
- Initialize your BYON node by following the steps documented here.
5. Define CI jobs and resources.
- Your CI jobs and resources are defined in a shippable.yml in a repository in a supported SCM. The list of supported SCM integrations are documented here.
- Create the shippable.yml in any of your configured SCM integration repository, except the source code repository that you are building itself. This approach offers several benefits such as controlling execute permissions on the jobsdefined in the yml since only users who have write permissions on the repository can execute the jobs defined in it as well as commits to the yml file not triggering the build job itself. You can for experimentation purposes create the shippable.yml file in the source code repository itself, but this will create the undesired side-effect of running the build job whenever the shippable.yml file is committed, since the build job needs the repository as an input in order for it to checkout the repository. We are in the meantime actively working on a feature that will solve this job triggering issue.
- We now define a gitRepo resource in shippable.yml that points to the repository that you want to build. This resourcecreates the necessary webhooks on your repository so that the job is automatically triggered on commits/prs/release tags.You can configure which webhooks you want to create, documented here.
- We now define a runSh job in shippable.yml. This job lets you run anybuild script in your gitRepo or a macOS shell command. You can also specify a custom docker image to the runshjob which has your build tool chain already preinstalled. Using shell commands in the runSh job, you can also install any tools or utilities you need during run time.
- Commit the file and create a syncRepo.
The repository containing your jobs and resources is called a Sync repository and represents your workflow configuration. Follow these instructions to import your configuration files into your Shippable account.
- Trigger your pipelineAfter you create the syncRepo, you can view the runSh job in the SPOG view.Right click on the job in the SPOG and click Run job. You can also trigger the job by committing changes to the repository.
