If you look around you see that Google Headphones are sometimes only partially supported and neatly integtrated into MacOS in comparison to their Apple counterparts. Most likely due to the nature of a full services eco-system, however there are Tools that can actually help you when you use Google Pixel Buds and MACOS. Check out the “PixelBudsMacOS”-Tool which gets you the same neat features, without the need to use the “https://mypixelbuds.google.com” website in the chrome-browser.
A native macOS menu-bar app for Google Pixel Buds Pro (Gen 1 & Gen 2). No Electron, no Chrome tab — talks to the buds directly over Bluetooth Classic RFCOMM using the reverse-engineered Maestro/Pigweed RPC protocol, plus Google Fast Pair (GFPS) for ring-my-buds.
