1. On darwin with m1 CPU, When run all tests with ninja -C out/host check command it will gives me this error:

The TestDnssd test is pretty broken. It makes a lot of assumptions that happen to be false in various cases, and are definitely false on m1/2/3 laptops.

[bzbarsky-apple]

@imsadegh In the meantime, you should be able to compile with --args='chip_enable_dnssd_tests=false' when doing your gn gen step to unblock you.
