To resolve this:
- Reboot into recovery mode to disable SIP (temporary limitation by Apple).
- Run in terminal.app (You may run either with root and non-root user):
- systemextensionsctl reset
- systemextensionsctl uninstall E8P47U2H32 com.trendmicro.icore.es and systemextensionsctl uninstall E8P47U2H32 com.trendmicro.icore.netfilter
- User will be prompted for credential for each command.
- Kill the process in the Activity Monitor.
After resetting, it is highly recommended to reboot macOS, as:
- A workaround to a bug in Network Extension framework
- A change to enable SIP
For additional reference in configuring SIP, refer to this Apple Developer article .
