Apple forbids modifying system items on Macs. The SIP limits the actions that the user can perform on protected parts of the Mac operating system. The problem is that, even if you have a third-party application, it may be able to create files that Apple thinks are default system files. In this way, such applications protect themselves from being deleted.So, to remove a problematic file or app, you would need to disable the Apple System Integrity Protection. Below, we will show how to do this.

Mobile Application Management (MAM) app protection policies allows you to manage and protect your organization's data within an application. Many productivity apps, such as the Microsoft Office apps, can be managed by Intune MAM. See the official list of Microsoft Intune protected apps available for public use.
You can create mobile app management policies for Office mobile apps that connect to Microsoft 365 services. You can also protect access to Exchange on-premises mailboxes by creating Intune app protection policies for Outlook for iOS/iPadOS and Android enabled with hybrid Modern Authentication. Before using this feature, make sure you meet the Outlook for iOS/iPadOS and Android requirements. App protection policies are not supported for other apps that connect to on-premises Exchange or SharePoint services.
MDM, in addition to MAM, makes sure that the device is protected. For example, you can require a PIN to access the device, or you can deploy managed apps to the device. You can also deploy apps to devices through your MDM solution, to give you more control over app management.
There are additional benefits to using MDM with App protection policies, and companies can use App protection policies with and without MDM at the same time. For example, consider an employee that uses both a phone issued by the company, and their own personal tablet. The company phone is enrolled in MDM and protected by App protection policies while the personal device is protected by App protection policies only.
You can use App protection policies to prevent company data from saving to the local storage of the device (see the image below). You can also restrict data movement to other apps that aren't protected by App protection policies. App protection policy settings include:
Any app that has been integrated with the Intune SDK or wrapped by the Intune App Wrapping Tool can be managed using Intune app protection policies. See the official list of Microsoft Intune protected apps that have been built using these tools and are available for public use.
The Outlook mobile app currently only supports Intune App Protection for Microsoft Exchange Online and Exchange Server with hybrid modern authentication and does not support Exchange in Office 365 Dedicated.
A managed location (i.e. OneDrive) is needed for Office. Intune marks all data in the app as either "corporate" or "personal". Data is considered "corporate" when it originates from a business location. For the Office apps, Intune considers the following as business locations: email (Exchange) or cloud storage (OneDrive app with a OneDrive for Business account).
There are additional requirements to use Skype for Business. See Skype for Business license requirements. For Skype for Business (SfB) hybrid and on-prem configurations, see Hybrid Modern Auth for SfB and Exchange goes GA and Modern Auth for SfB OnPrem with Azure AD, respectively.
Once enabled, the OneDrive and SharePoint apps for iOS/iPadOS and Android are protected with the selected settings by default. An IT Pro can edit this policy in the Microsoft Endpoint Manager admin center to add more targeted apps and to modify any policy setting.
Intune PIN securityThe PIN serves to allow only the correct user to access their organization's data in the app. Therefore, an end user must sign in with their work or school account before they can set or reset their Intune app PIN. This authentication is handled by Azure Active Directory via secure token exchange and is not transparent to the Intune SDK. From a security perspective, the best way to protect work or school data is to encrypt it. Encryption is not related to the app PIN but is its own app protection policy.
In order to support this feature and ensure backward compatibility with previous versions of the Intune SDK for iOS/iPadOS, all PINs (either numeric or passcode) in 7.1.12+ are handled separately from the numeric PIN in previous versions of the SDK. Another change was introduced in the Intune SDK for iOS v 14.6.0 that causes all PINs in 14.6.0+ to be handled separately from any PINs in previous versions of the SDK.
When On-Premises (on-prem) services don't work with Intune protected appsIntune app protection depends on the identity of the user to be consistent between the application and the Intune SDK. The only way to guarantee that is through modern authentication. There are scenarios in which apps may work with an on-prem configuration, but they are neither consistent nor guaranteed.
Intune app protection policies allow control over app access to only the Intune licensed user. One of the ways to control access to the app is to require either Apple's Touch ID or Face ID on supported devices. Intune implements a behavior where if there is any change to the device's biometric database, Intune prompts the user for a PIN when the next inactivity timeout value is met. Changes to biometric data include the addition or removal of a fingerprint, or face. If the Intune user does not have a PIN set, they are led to set up an Intune PIN.
The intent of this process is to continue keeping your organization's data within the app secure and protected at the app level. This feature is only available for iOS/iPadOS, and requires the participation of applications that integrate the Intune SDK for iOS/iPadOS, version 9.0.1 or later. Integration of the SDK is necessary so that the behavior can be enforced on the targeted applications. This integration happens on a rolling basis and is dependent on the specific application teams. Some apps that participate include WXP, Outlook, Managed Browser, and Yammer.
Users can disable an app's Universal Links by visiting them in Safari and selecting Open in New Tab or Open. In order to user Universal Links with Intune app protection policies, it's important to re-enable the universal links. The end user would need to do an Open in in Safari after long pressing a corresponding link. This should prompt any additional protected app to route all Universal Links to the protected application on the device.
The Teams app on Microsoft Teams Android devices does not support APP (does not receive policy through the Company Portal app). This means that app protection policy settings will not be applied to Teams on Microsoft Teams Android devices. If you have app protection policies configured for these devices, consider creating a group of Teams device users and exclude that group from the related app protection policies. Additionally, consider modifying your Intune Enrollment Policy, Conditional Access Policies and Intune Compliance policies so they have supported settings. If you cannot change your existing policies, you must configure (exclusion) Device Filters. Verify each setting against the existing Conditional Access configuration and Intune Compliance policy to know if you have unsupported settings. For related information see Supported Conditional Access and Intune device compliance policies for Microsoft Teams Rooms and Teams Android Devices. For information related to Microsoft Teams Rooms, see Conditional Access and Intune compliance for Microsoft Teams Rooms.
Public apps are supported are apps from Microsoft and partners that are commonly used with Microsoft Intune. These Intune protected apps are enabled with a rich set of support for mobile application protection policies. For more information, see Microsoft Intune protected apps. Custom apps are LOB apps that have been integrated with the Intune SDK or wrapped by the Intune App Wrapping Tool. For more information see Microsoft Intune App SDK Overview and Prepare line-of-business apps for app protection policies.
You can edit an existing policy and apply it to the targeted users. However, when you change existing policies, users who are already signed in to the apps won't see the changes for an eight-hour period.
After your changes to the assignments are ready, select Save to save the configuration and deploy the policy to the new set of users. If you select Cancel before you save your configuration, you will discard all changes you've made to the Include and Exclude tabs.
Select the Save to save your changes. Repeat the process to select a settings area and modify and then save your changes, until all your changes are complete. You can then close the Intune App Protection - Properties pane.
In many organizations, it's common to allow end users to use both Intune Mobile Device Management (MDM) managed devices, such as corporate owned devices, and un-managed devices protected with only Intune app protection policies. Unmanaged devices are often known as Bring Your Own Devices (BYOD).
When you are in protected view, editing is locked, so you can't cursor around the document as expected. However, if you need to navigate through a document in Protected View with a screen reader, you can press F7 to turn on caret browsing. This action should allow you to navigate through the text without being in edit mode.
iCloud already protects 14 sensitive data categories using end-to-end encryption by default, including passwords in iCloud Keychain and Health data. For users who enable Advanced Data Protection, the total number of data categories protected using end-to-end encryption rises to 23, including iCloud Backup, Notes, and Photos. The only major iCloud data categories that are not covered are iCloud Mail, Contacts, and Calendar because of the need to interoperate with the global email, contacts, and calendar systems. 2ff7e9595c
