Mac.apk runs Android apps as native Mac processes, with no emulator or VM (github.com)
Mac.apk implements the Android app environment directly on Apple Silicon macOS. Apps appear in the Dock with their own windows and draw through the GPU. It is alpha: 10 of 66 tested apps only partly work and 4 don't run.
The README warns that saved data lives inside each app's bundle, so trashing the app erases it. A commenter says the newest release moves it to Application Support.
