Because Apple has strengthened network security in macOS 26 (Tahoe), Karing requires additional "System Extension" authorization upon first launch to function properly. This tutorial will guide you through the setup process step by step.
⚠️ Scope of Application
After opening the Karing App, two notification windows will appear simultaneously:
Left: macOS system pop-up
Right side: Karing's tooltip
Please note:
Do not click "OK"
Please select "Open System Settings"

After clicking "Open System Settings," the system will automatically take you to System Settings.
On this page, find Karing's extended features and click "Enable."
Return to the Karing App to use it normally.

If you closed the prompt, please manually enable the extended features by following these steps:
Open System Settings
Click in sequence: [General] → [Login Items & Extensions] → [Extensions] → [By Category] → [Network Extensions]
Find Karing in the list and enable it.

After completing the above steps, Karing should run normally on macOS 26.
App Store Installation: No action is required; the system will automatically enable it.
