Traffic Lights+ is a native macOS menu bar utility that makes the close, minimize, and zoom buttons in the top-left corner of any window bigger and easier to click. Many people find those small circular controls hard to hit precisely, and this app addresses that without modifying any system files, injecting code into other applications, or requiring System Integrity Protection to be turned off. According to the README, a user can adjust the size of the enlarged controls between 18 and 48 points, change the spacing between the circular buttons or switch to a square style flush with the window's corner, and choose whether hovering near the corner reveals the whole group of buttons or just the single nearest one. Each of the red, yellow, and green controls can be set independently to close the window, quit the app, minimize, zoom, hide the app, or do nothing at all. There is also an option to minimize the current window by clicking its Dock icon again, and the app tracks window position in real time, including while dragging, so the enlarged buttons stay correctly placed and properly hidden when covered by another window. The app requires macOS 13 Ventura or later and works on both Apple Silicon and Intel Macs, though full-screen window support is still listed as in development. Setup involves installing the app from a downloaded disk image and then granting it Accessibility permission, which the README says is used only to find standard window buttons, read window positions, and carry out the actions the user configured, not for anything else. The README explains that macOS has no public way to resize a window's built-in traffic-light buttons across applications, so the app instead reads window information through the Accessibility API and draws its own enlarged buttons in separate overlay panels. Everything runs locally, with no network access beyond checking for software updates, and no analytics or account system. The project can be built from source with Swift and is released under the MIT license.
