Erasing a disk or volume permanently deletes all of its files. Before continuing, make sure that you have a backup of any files that you want to keep.

How to erase your disk

Start up from macOS Recovery. Then select Disk Utility from the Utilities window and click Continue.
If you're not erasing the disk your Mac started up from, you don't need to start up from macOS Recovery: just open Disk Utility from the Utilities folder of your Applications folder.
Choose View > Show All Devices from the menu bar in Disk Utility. The sidebar now shows your disks (devices) and any containers and volumes within them. The disk your Mac started up from is at the top of the list. In this example, Apple SSD is the startup disk:
Select the disk that you want to erase. Don't see your disk?
Click Erase, then complete these items:
- Name: Type the name that you want the disk to have after you erase it.
- Format: Choose APFS or Mac OS Extended (Journaled). Disk Utility shows a compatible format by default.
- Scheme: Choose GUID Partition Map.
Click Erase to begin erasing your disk and every container and volume within it. You might be asked to enter your Apple ID. Forgot your Apple ID?
When done, quit Disk Utility.
If you want your Mac to be able to start up from the disk you erased, reinstall macOS on the disk.

How to erase a volume on your disk

Start up from macOS Recovery. Then select Disk Utility from the Utilities window and click Continue.
If you're not erasing the volume your Mac started up from, you don't need to start up from macOS Recovery: just open Disk Utility from the Utilities folder of your Applications folder.
In the sidebar of Disk Utility, select the volume that you want to erase. The volume your Mac started up from is named Macintosh HD, unless you changed its name. Don't see your volume?
Click Erase, then complete these items:
- Name: Type the name that you want the volume to have after you erase it.
- Format: Choose APFS or Mac OS Extended (Journaled). Disk Utility shows a compatible format by default.
If you see an Erase Volume Group button, the volume you selected is part of a volume group. In that case, you should erase the volume group. Otherwise, click Erase to erase just the selected volume. You might be asked to enter your Apple ID. Forgot your Apple ID?
When done, quit Disk Utility.
If you want your Mac to be able to start up from the volume you erased, reinstall macOS on that volume.

Reasons to erase

You can erase at any time, including in circumstances such as these:

You want to permanently erase all content from your Mac and restore it to factory settings. This is one of the final steps before selling, giving away, or trading in your Mac.
You're changing the format of a disk, such as from a PC format (FAT, ExFAT, or NTFS) to a Mac format (APFS or Mac OS Extended).
You received a message that your disk isn't readable by this computer.
You're trying to resolve a disk issue that Disk Utility can't repair.
The macOS installer doesn't see your disk or can't install on it. For example, the installer might say that your disk isn't formatted correctly, isn't using a GUID partition scheme, contains a newer version of the operating system, or can't be used to start up your computer.
The macOS installer says that you may not install to this volume because it is part of an Apple RAID.

About APFS and Mac OS Extended

Disk Utility in macOS High Sierra or later can erase using either the newer APFS (Apple File System) format or the older Mac OS Extended format, and it automatically chooses a compatible format for you.

How to choose between APFS and Mac OS Extended

Disk Utility tries to detect the type of storage and show the appropriate format in the Format menu. If it can't, it chooses Mac OS Extended, which works with all versions of macOS. If you want to change the format, answer these questions:

Are you formatting the disk that came built into your Mac?
If the built-in disk came APFS-formatted, Disk Utility suggests APFS. Don't change it to Mac OS Extended.
Are you about to install macOS High Sierra or later for the first time on the disk?
If you need to erase your disk before installing High Sierra or later for the first time on that disk, choose Mac OS Extended (Journaled). During installation, the macOS installer decides whether to automatically convert to APFS—without erasing your files.
Are you preparing a Time Machine backup disk or bootable installer?
Choose Mac OS Extended (Journaled) for any disk that you plan to use as a Time Machine backup disk or as a bootable installer.
Will you be using the disk with another Mac?
If the other Mac isn't using macOS High Sierra or later, choose Mac OS Extended (Journaled). Earlier versions of macOS don't work with APFS-formatted volumes.

How to identify the format currently in use

If you want to know which format is currently in use, use any of these methods:

Select the volume in the Disk Utility sidebar, then check the information shown on the right. For more detail, choose File > Get Info from the Disk Utility menu bar.
Open System Information and select Storage in the sidebar. The File System column on the right shows the format of each volume.
Select the volume in the Finder, then choose File > Get Info from the menu bar. The Get Info window shows the Format of that volume.

If your disk or volume doesn't appear, or the erase fails

Shut down your Mac, then unplug all nonessential devices from your Mac.
If you're erasing an external drive, make sure that it's connected directly to your Mac using a cable that you know is good. Then turn the drive off and back on.
If your disk or volume still doesn't appear in Disk Utility, or Disk Utility reports that the erase process failed, your disk or Mac might need service. If you need help, please contact Apple Support.

If you can't start up from macOS Recovery, you can use a different startup disk instead.
If Disk Utility shows a Security Options button in the Erase window, you can click that button to choose between a faster (but less secure) erase and a slower (but more secure) erase. Some older versions of Disk Utility offer the option to zero all data instead. These secure-erase options aren't offered or needed for solid-state drives (SSDs) and flash storage.

Intune includes built-in settings to customize features on your macOS devices. For example, administrators can add AirPrint printers, choose how users sign in, configure the power controls, use single sign-on authentication, and more.

Use these features to control macOS devices as part of your mobile device management (MDM) solution.

This article lists these settings, and describes what each setting does. It also lists the steps to get the IP address, path, and port of AirPrint printers using the Terminal app (emulator). For more information on device features, go to Add iOS/iPadOS or macOS device feature settings.

Note

The user interface may not match the enrollment types in this article. The information in this article is correct. The user interface is being updated in an upcoming release.

Before you begin

Create a macOS device features profile.

Note

These settings apply to different enrollment types, with some settings applying to all enrollment options. For more information on the different enrollment types, see macOS enrollment.

AirPrint

Settings apply to: All enrollment types

AirPrint destinations: Add one or more AirPrint printers users can print from their devices. Also enter:
- Port (iOS 11.0+, iPadOS 13.0+): Enter the listening port of the AirPrint destination. If you leave this property blank, AirPrint uses the default port.
- IP address: Enter the IPv4 or IPv6 address of the printer. For example, enter 10.0.0.1. If you use host names to identify printers, you can get the IP address by pinging the printer in the Terminal app. Get the IP address and path (in this article) has more details.
- Path: Enter the resource path of the printer. The path is typically ipp/print for printers on your network. Get the IP address and path (in this article) has more details.
- TLS (iOS 11.0+, iPadOS 13.0+): Your options:
  - No (default): Transport Layer Security (TLS) isn't enforced when connecting to AirPrint printers.
  - Yes: Secures AirPrint connections with Transport Layer Security (TLS).
Import a comma-separated file (.csv) that includes a list of AirPrint printers. Also, after you add AirPrint printers in Intune, you can Export this list.

Get the IP address and path

To add AirPrinter servers, you need the IP address of the printer, the resource path, and the port. The following steps show you how to get this information.

On a Mac that's connected to the same local network (subnet) as the AirPrint printers, open Terminal (from /Applications/Utilities).
In the Terminal app, type ippfind, and select enter.
Note the printer information. For example, it may return something similar to ipp://myprinter.local.:631/ipp/port1. The first part is the name of the printer. The last part (ipp/port1) is the resource path.
In the Terminal, type ping myprinter.local, and select enter.
Note the IP address. For example, it may return something similar to PING myprinter.local (10.50.25.21).
Use the IP address and resource path values. In this example, the IP address is 10.50.25.21, and the resource path is /ipp/port1.

Associated domains

In Intune, you can:

Add many app-to-domain associations.
Associate many domains with the same app.

This feature applies to:

macOS 10.15 and newer

Settings apply to: User approved device enrollment, and Automated device enrollment

Associated domains: Add an association between your domain and an app. This feature shares sign on credentials between a Contoso app and a Contoso website. Also enter:
- App ID: Enter the app identifier of the app to associate with a website. The app identifier includes the team ID and a bundle ID: TeamID.BundleID.
  The team ID is a 10-character alphanumerical (letters and numbers) string generated by Apple for your app developers, such as ABCDE12345. Locate your Team ID (opens Apple's web site) has more information.
  The bundle ID uniquely identifies the app, and typically is formatted in reverse domain name notation. For example, the bundle ID of Finder is com.apple.finder. To find the bundle ID, use the AppleScript in Terminal:
  osascript -e 'id of app 'ExampleApp'
- Domain: Enter the website domain to associate with an app. The domain includes a service type and fully qualified hostname, such as webcredentials:www.contoso.com.
  You can match all subdomains of an associated domain by entering *. (an asterisk wildcard and a period) before the beginning of the domain. The period is required. Exact domains have a higher priority than wildcard domains. So, patterns from parent domains are matched if a match isn't found at the fully qualified subdomain.
  The service type can be:
  - authsrv: Single sign-on app extension
  - applink: Universal link
  - webcredentials: Password autofill

Tip

To troubleshoot, on your macOS device, open System Preferences > Profiles. Confirm the profile you created is in the device profiles list. If it's listed, be sure the Associated Domains Configuration is in the profile, and it includes the correct app ID and domains.

Content caching

Content caching saves a local copy of content. This information can be retrieved by other Apple devices without connecting to the Internet. This caching accelerates downloads by saving software updates, apps, photos, and other content the first time they're downloaded. Since apps are downloaded once and shared to other devices, schools and organization with many devices save bandwidth.

Note

Only use one profile for these settings. If you assign multiple profiles with these settings, an error occurs.

For more information on monitoring content caching, see View content caching logs and statistics (opens Apple's web site).

This feature applies to:

macOS 10.13.4 and newer

Settings apply to: All enrollment types

For more information on these settings, see Content Caching payload settings (opens Apple's web site).

Enable content caching: Yes turns on content caching, and users can't disable it. When set to Not configured (default), Intune doesn't change or update this setting. By default, the OS might turn it off.

Type of content to cache: Your options:
- All content: Caches iCloud content and shared content.
- User content only: Caches user's iCloud content, including photos and documents.
- Shared content only: Caches apps and software updates.
Maximum cache size: Enter the maximum amount of disk space (in bytes) that's used to cache content. When left blank (default), Intune doesn't change or update this setting. By default, the OS might set this value to zero (0) bytes, which gives unlimited disk space to the cache.
Be sure you don't exceed the space available on the devices. For more information on device storage capacity, see How iOS and macOS report storage capacity (opens Apple's web site).
Cache location: Enter the path to store the cached content. The default location is /Library/Application Support/Apple/AssetCache/Data. It's recommended that you don't change this location.
If you change this setting, your cached content isn't moved to the new location. To move it automatically, users need to change the location on the device (System Preferences > Sharing > Content Caching).
Port: Enter the TCP port number on devices for the cache to accept download and upload requests, from 0-65535. Enter zero (0) (default) to use whatever port is available.
Block internet connection and cache content sharing: Also known as tethered caching. Yes prevents Internet connection sharing, and prevents sharing cached content with iOS/iPadOS devices USB-connected to their Mac. Users can't enable this feature. When set to Not configured (default), Intune doesn't change or update this setting.
Enable internet connection sharing: Also known as tethered caching. Yes allows Internet connection sharing, and allows sharing cached content with iOS/iPadOS devices USB-connected to their Mac. Users can't disable this feature. When set to Not configured (default), Intune doesn't change or update this setting. By default, the OS might turn this off.
This feature applies to:
- macOS 10.15.4 and newer
Enable cache to log client details: Yes logs the IP address and port number of the devices that request content. If you're troubleshooting device issues, this log file may help. When set to Not configured (default), Intune doesn't change or update this setting. By default, the OS might not log this information.
Always keep content from the cache, even when the system needs disk space for other apps: Yes keeps the cache content, and makes sure nothing is deleted, even when disk space is low. When set to Not configured (default), Intune doesn't change or update this setting. By default, the OS might purge content from the cache automatically when it needs storage space for other apps.
This feature applies to:
- macOS 10.15 and newer
Show status alerts: Yes shows as alerts as system notifications. When set to Not configured (default), Intune doesn't change or update this setting. By default, the OS might not show these alerts as system notifications.
This feature applies to:
- macOS 10.15 and newer
Prevent the device from sleeping while caching is turned on: Yes prevents the computer from going to sleep when caching is on. When set to Not configured (default), Intune doesn't change or update this setting. By default, the OS might allow the device to sleep.
This feature applies to:
- macOS 10.15 and newer
Devices to cache: Choose the devices that can cache content. Your options:
- Not configured (default): Intune doesn't change or update this setting.
- Devices using the same local network: The content cache offers content to devices on the same immediate local network. No content is offered to devices on other networks, including devices reachable by the content cache.
- Devices using the same public IP address: The content cache offers content to devices using the same public IP address. No content is offered to devices on other networks, including devices reachable by the content cache.
- Devices using custom local networks: The content cache provides content to devices in the IP ranges you enter.
  - Client listen ranges: Enter the range of IP addresses that can receive the content cache.
- Devices using custom local networks with fallback: The content cache provides content to devices in the listen ranges, peer listen ranges, and parents IP addresses.
  - Client listen ranges: Enter the range of IP addresses that can receive the content cache.
Custom public IP addresses: Enter a range of public IP addresses. The cloud servers use this range to match client devices to caches.
Share content with other caches: When your network has more than one content cache, the content caches on other devices automatically become peers. These devices can consult and share cached software.
When a requested item isn’t available on one content cache, it checks its peers for the item. If the item is available, it’s downloaded from the content cache on the peer device. If it’s still not available, the content cache downloads the item from:
- A parent IP address, if any are configured
  OR,
- From Apple through the Internet
When more than one content cache is available, devices automatically select the right content cache.
Your options:
- Not configured (default): Intune doesn't change or update this setting.
- Content caches using the same local networks: Content cache only peers with other content caches on the same immediate local network.
- Content caches using the same public IP address: Content cache only peers with other content caches on the same public IP address.
- Content caches using custom local networks: Content cache only peers with other content caches in the IP address listen range you enter:
  - Peer listen ranges: Enter the IPv4 or IPv6 start and ending IP addresses for your range. The content cache responds only to peer cache requests from content caches in the IP address ranges you enter.
  - Peer filter ranges: Enter the IPv4 or IPv6 start and ending IP addresses for your range. The content cache filters its list of peers using the IP address ranges you enter.
Parent IP addresses: Enter the local IP address of another content cache to add as a parent cache. Your cache uploads and downloads content to these caches, instead of uploading/downloading directly with Apple. Only add a parent IP address once.
Parent selection policy: When there are many parent caches, select how the parent IP address is chosen. Your options:
- Not configured (default): Intune doesn't change or update this setting.
- Round robin: Use the parent IP addresses in order. This option is good for load-balancing scenarios.
- First available: Always use the first available IP address in the list.
- Hash: Creates a hash value for the path portion of the requested URL. This option makes sure the same parent IP address is always used for the same URL.
- Random: Randomly use an IP address in the list. This option is good for load-balancing scenarios.
- Sticky available: Always use the first IP address in the list. If it's not available, then use the second IP address in the list. Continue to use the second IP address until it's not available, and so on.
