+
+::: info Note
+TUN mode requires certain permissions.
+
+- On Windows, run Clash Nyanpasu as an administrator to enable TUN mode.
+- On macOS, click the Settings icon next to Clash Kernel on the Settings page, open kernel settings, click the small lock icon on the kernel side, enter the password for authorization, and restart the kernel.
+- On Linux, similar to macOS, you can run with sudo to achieve authorization.

+
+#### Manual Authorization on macOS
+

+# clash core
+sudo chown root:admin /Applications/Clash\ Nyanpasu.app/Contents/MacOS/clash
+sudo chmod +sx /Applications/Clash\ Nyanpasu.app/Contents/MacOS/clash
