Fix Full Disk Access Error in Trend Micro Antivirus on Mac

You see this error message after installing Trend Micro Antivirus on your Mac.

"Full Disk Access required to protect your files"

What is Full Disk Access?

Full Disk Access is a security feature, introduced in macOS Mojave, that requires applications to be given full permission to access user-protected files. If not enabled, some data on the Mac will not be accessible.

In previous macOS versions, this permission was automatically given during installation.

Why Did This Happen?

For Trend Micro Antivirus to scan protected files, you must allow Full Disk Access to the iCoreService file, an important component of the program.

1. Open Trend Micro Antivirus.
2. Click the Allow Full Disk Access button.

   

3. A new window will appear. Click the Open Full Disk Access button.

   

4. Enable Trend Micro Antivirus and Trend Micro Antivirus Extension.
