Clamshell mode without closing your MacBook
You want one screen. The big one. Clamshell needs a charger. Brightness to zero doesn't disable it. Apps still open there. OneDisplay fixes this with one click. Click the menu bar icon, MacBook display turns off, only your external monitor stays on. Click again to bring it back. No setup. No background process. No configuration. Works on Apple Silicon (M1, M2, M3, M4) and macOS Ventura or later. $9. One-time. Yours forever. Not happy? Full refund, no questions asked.

Built this because I wanted to use my external monitor only without closing the lid. Spent a weekend reverse engineering the private API macOS uses internally. Happy to answer any questions about how it works!
