Network protection available for macOS

Known issues

Apple fixed an issue on macOS Ventura upgrade, which is fixed 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 controls ability to intercept and block access to Bluetooth devices. At this time, the recommended mitigation is to use a version of macOS less than 14.3.1.

Sonoma support

Microsoft Defender supports macOS Sonoma (14.0) in the current Defender release.

 Published: Feb 28, 2022
 Build: 101.59.50
 Release version: 20.122021.15950.0

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. **\n

• Improved the handling of device control policies containing invalid vendor IDs and product IDs. Before this version, if the policy contained one or more invalid IDs, the entire policy was ignored. Starting from this version, only the invalid portions of the policy are ignored. Issues with the policy are surfaced through mdatp device-control removable-media policy list.

• 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.
