Hi, donevans!


Welcome to Trend Micro Home Users Community.


The "Legacy System Extension" notification appears after installing Antivirus for Mac to macOS version 10.15.4. This message appears because Antivirus for Mac will need to be updated to improve compatibility with the new Mac operating system. Rest assured, Trend Micro Antivirus for Mac works with the latest Mac version and its earlier versions. We will be releasing a compatible version of Antivirus for Mac to comply with the next macOS requirements and to ensure that you have continuous protection for your Mac.
