What about macOS?
The macOS application is still completing native Apple Silicon validation and is not offered here yet. We publish an architecture only after its installation and core scan journey pass on the intended hardware.
What about Windows?
Windows is not a Chowder launch target and is not marketed or sold. Windows customers already have Microsoft Defender; retained Windows engineering is deferred.
