odourless

Odourless is a tool for preventing .DS_Store creation. It works on MacOS latest Catalina.

Alpha version! Use it at your own risk!

How it works

It use mach_inject to inject Finder.app and frida-gum to replace some syscall including open, openx_np, getattrlist, setattrlist.

Whenever Finder try call these function with .DS_Store file, it will replace the path to a fake one under the odourless cage directory /usr/local/var/.odourless_cage.

As you see, it do not delete .DS_Store, but place all .DS_Store into one directory that you donot care about.

Many thanks to @darwin and @JK3Y !
