Known issues

Apple fixed an issue on macOS Ventura upgrade and macOS Sonoma upgrade with the latest OS update. The issue impacts Microsoft Defender for Endpoint security extensions, and might result in losing Full Disk Access Authorization, impacting its ability to function properly.
In macOS Sonoma 14.3.1, Apple made a change to the handling of Bluetooth devices that impacts Defender for Endpoint device control's ability to intercept and block access to Bluetooth devices. At this time, the recommended mitigation is to use a version of macOS earlier than 14.3.1.

Sequoia support

In macOS Sequoia (version 15.0), if you have Network Protection enabled, you might see crashes of the network extension (NetExt). This issue results in intermittent network connectivity issues for end users.

Note

The core functionalities of antivirus, endpoint detection & response, and threat and vulnerability management continue functioning.
We're recommending that customers who have Network Protection enabled in their organization to either:
1. Delay updating to macOS Sequoia (version 15.0); or
2. Use the instructions to disable Network Extension as described in Troubleshoot NetExt issues in Microsoft Defender for Endpoint on Mac. This causes Network Protection, Web Content Filtering, and IP address/URL Indicators to be nonfunctional.
Microsoft Defender is collaborating with Apple to provide our mutual customers a solution when Network Protection is enabled in Microsoft Defender for Endpoint on macOS Sequoia (version 15.0).

macOS Deprecation

Microsoft Defender for Endpoint no longer supports Big Sur (11).
macOS 12 (Monterey) will not be supported starting December 2024.

Releases for Defender for Endpoint on Mac

Behavior Monitoring for macOS is now in public preview

Behavior monitoring monitors process behavior to detect and analyze potential threats based on the behavior of the applications, daemons, and files within the system. As behavior monitoring observes how the software behaves in real-time, it can adapt quickly to new and evolving threats and block them. To learn more, see Behavior Monitoring in Microsoft Defender for Endpoint on macOS.

What's new

This version adds support for macOS 12.3. Starting with macOS 12.3, Apple is removing Python 2.7. There's no Python version preinstalled on macOS by default. ACTION NEEDED:
- Users must update Microsoft Defender for Endpoint for Mac to version 101.59.50 (or newer) before updating their devices to macOS Monterey 12.3 (or newer). This minimal version 101.59.50 is a prerequisite to eliminating Python-related issues with Microsoft Defender for Endpoint for Mac on macOS Monterey.
- For remote deployments, existing MDM setups must be updated to Microsoft Defender for Endpoint for Mac version 101.59.50 (or newer). Pushing via MDM an older Microsoft Defender for Endpoint for Mac version to macOS Monterey 12.3 (or newer) results in an installation failure.

Resolved an issue where some VPN applications couldn't connect due to the network content filter that is distributed with Microsoft Defender for Endpoint for Mac
Addressed an issue discovered in macOS 12.2 preview 2 where the installation package couldn't be opened due to a change in the operating system (OS) that prevents installation of packages with certain characteristics. While it appears that this OS change isn't included in the final release of macOS 12.2, it's likely that it will be reintroduced in a future macOS version. As such, we encourage all enterprise administrators to refresh the Microsoft Defender for Endpoint package in their management console to this product version (or a newer version).
Addressed an issue seen on some M1 devices where the product was stuck with invalid anti-malware definitions and couldn't successfully update to a working set of definitions.

Caution

To ensure the most complete protection for your macOS devices and in alignment with Apple stopping delivery of macOS native security updates to OS versions older than [current - 2], MDATP for Mac deployment and updates will no longer be supported on macOS Sierra [10.12]. MDATP for Mac updates and enhancements will be delivered to devices running versions Catalina [10.15], Mojave [10.14], and High Sierra [10.13].

If you already have MDATP for Mac deployed to your Sierra [10.12] devices, please upgrade to the latest macOS version to eliminate risks of losing protection.

Caution

macOS 10.15 (Catalina) contains new security and privacy enhancements. Beginning with this version, by default, applications are not able to access certain locations on disk (such as Documents, Downloads, Desktop, etc.) without explicit consent. In the absence of this consent, Microsoft Defender for Endpoint is not able to fully protect your device.

The mechanism for granting this consent depends on how you deployed Microsoft Defender for Endpoint:

For manual deployments, see the updated instructions in the Manual deployment topic.

For managed deployments, see the updated instructions in the JAMF-based deployment and Microsoft Intune-based deployment articles.
