Create a folder named 'YourApplication.app'. It can be created at any location that is convenient to your usage. Though, the most OS compliant locations may be /Applications or your own /Applications folder. Put your script file directly in this folder the way that suites you the best (Finder, terminal etc). When you turn on your Mac, various apps, add-ons, and invisible background processes start running all by themselves. This is usually what you want. $ appify your-shell-script.sh 'Your App Name' Obviously, this would create a stand-alone application named Your App Name.app that executes the your-shell-script.sh script. After that, you can very easily add a custom icon to the app if you want to. Adding a custom app icon. Mac App Store: Click a Button to Install an App. We’re all used to app stores on our phones, but on the desktop they remain an oddity. Still, the Mac App Store is a decent first place to check. Open the store, search for the app you want, and click “Get” then “Download.”.
A daemon is a program running in the background without requiring user input. A typical daemon might for instance perform daily maintenance tasks or scan a device for malware when it is connected.
launchd differentiates between agents and daemons. The main difference is that an agent is run on behalf of the logged in user while a daemon runs on behalf of the root user or any user you specify with the UserName key.
The behavior of a daemon/agent is specified in a special XML file called a property list. Depending on where it is stored it will be treated as a daemon or an agent.
Job definitions crucial for the operation of the operating system are stored below /System/Library. You should never need to create a daemon or agent in these directories. Third-Party definitions which are relevant for every user are stored below /Library. Job definitions for a specific user are stored below the respective user's Library directory.
| Type | Location | Run on behalf of |
|---|---|---|
| User Agents | ~/Library/LaunchAgents | Currently logged in user |
| Global Agents | /Library/LaunchAgents | Currently logged in user |
| Global Daemons | /Library/LaunchDaemons | root or the user specified with the key UserName |
| System Agents | /System/Library/LaunchAgents | Currently logged in user |
| System Daemons | /System/Library/LaunchDaemons | root or the user specified with the key UserName |

The following example shows a complete job definition with only three keys:
- Label This key is required for every job definition. It identifies the job and has to be unique for the launchd instance. Theoretically it is possible for an agent to have the same label as a daemon, as daemons are loaded by the root launchd whereas agents are loaded by a user launchd, but it is not recommended.
- Program This key defines what to start, in this case a shell script /Users/Me/Scripts/cleanup.sh.
- RunAtLoad This is one of several optional keys specifying when the job should be run, in this case right after it has been loaded.
launchd supports more than 36 different configuration keys. Most of them are explained in the Configuration-Section of this primer.
Upon system start the root launchd process will scan the daemon directories /System/Library/LaunchDaemons and /Library/LaunchDaemons for job definitions and load them depending on the existence/value of the Disabled key and the contents of the override database.
When a user logs in a new launchd process will be started for this user. This launchd process will scan the agent directories /System/Library/LaunchAgents, /Library/LaunchAgents and ~/Library/LaunchAgents for job definitions and load them depending on the existence/value of the Disabled key and the contents of the override database.
Loading a job definition does not necessarily mean to start the job. When a job is started is determined by the job definition. In fact, only when RunAtLoad or KeepAlive have been specified,launchd will start the job unconditionally when it has been loaded.
How to give apps permission to use your location
Some apps might not work unless you turn on Location Services.1 The first time an app needs to access your Location Services information, you'll get a notification asking for permission. Choose one of these options:
Free Script App
- Tap Allow to let the app use Location Services information as needed.
- Tap Don't Allow to prevent access.2
- Tap Ask Next Time to choose Always While Using App, Allow Once, or Don't Allow.
Maintenance Scripts Mac
iOS devices might use Wi-Fi and Bluetooth to determine your location. GPS and cellular location are available on iPhone and iPad (Wi-Fi + Cellular) models.
How to turn Location Services on or off for specific apps
- Go to Settings > Privacy > Location Services.
- Make sure that Location Services is on.
- Scroll down to find the app.
- Tap the app and select an option:
- Never: Prevents access to Location Services information.
- Ask Next Time: This allows you to choose Always While Using App, Allow Once, or Don't Allow.
- While Using the App: Allows access to Location Services only when the app or one of its features is visible on screen. If an app is set to While Using the App, you might see your status bar turn blue with a message that an app is actively using your location.
- Always: Allows access to your location even when the app is in the background.
From here, apps should provide an explanation of how the app will use your location information. Some apps might offer only two options. Learn more about privacy and Location Services.

- Location Services uses GPS and Bluetooth (where they're available), along with crowd-sourced Wi-Fi hotspots and cellular towers to determine the approximate location of your device.
- Apps won't use your location until they ask for your permission and you allow permission.
