Why do I get the System Extension Blocked notification on macOS 10.13 (High Sierra)?

Among the features introduced in the recent macOS High Sierra, there are also changes to the Kernel Extensions (KEXT) that are not signed by Apple. Third-party KEXT are no longer automatically installed and require user approval before loading.



To install Endpoint Protector on macOS 10.13 and approve system extensions signed by CoSoSys, follow the below steps:

1. Go to the System Preferences and select Security & Privacy.
2. Select the General tab and click the Lock icon on the bottom left to allow changes.
3. Click the Allow button next to the prompt System software from developer “CoSoSys” was blocked from loading.



4. In some circumstances, the OS will also prompt for a restart.

In case the issue persists, please contact Support.
