A new system for v2ray and clash has been introduced, which allows for a direct installation using 'brew install v2ray clash' and copying the previous configuration. Some concerns may arise regarding the security implications, as the original source code of clash is no longer available. Moreover, it is uncertain whether the version of clash provided by Homebrew is genuine. In recent times, we have seen a proliferation of new and innovative protocols, such as Hysteria and sing-box, which may potentially render old tools obsolete.
