By default, Proxyman will automatically override your Network Proxy Setting by using networksetup CLI. However, networksetup is bottleneck when starting or quitting the app.
Proxyman offers a better approach: Proxy Setting Helper Tool, which is Privileged Helper Tool macOS in order to override Network Proxy in high performance.
At the first launch, Proxyman will present the Popup to install the Proxyman Proxy Setting Tool. You can skip it and install later in Preference -> Advanced Tab
Install Proxy Helper tool require privilege permission.
You can uninstall the Proxy Helper Tool in Preference -> Advance Tab -> Uninstall Proxy Setting Tool
