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.
