Getting a "can't verify the developer" warning?
If you see a warning on first launch, go to System Settings > Privacy & Security and click "Open Anyway". Open source software usually isn't signed with an Apple developer certificate, which is normal.
Clicking "Download" takes you to a source confirmation page first; the download starts after confirmation.
About Watt Toolkit
Watt Toolkit (formerly known as Steam++) is an open-source, cross-platform game toolbox licensed under GPL-3.0. It provides network acceleration through a local reverse proxy, enabling smoother access to gaming websites. It supports quick switching between multiple platform accounts and management of family shared libraries. Users can manage Steam game inventories, customize covers, and handle cloud saves and achievements. The built-in local token feature supports importing HOTP/TOTP/Steam tokens and batch confirmation of transactions. It primarily supports Windows 10 1809 and later, macOS 10.15 and later, and Ubuntu 20.04 and later. Some features require the Steam client to be installed.
