valet: The ping test after installation doesn't work

Hi everyone,

I just installed for the first time Valet on my Mac. So i did all the process for the installation.

1 / Installed HomeBrew 2 / Installed PHP 7.3 with a homebrew install php@7.3 & composer in global mode 3 / Did the composer global require laravel/valet

I had no problems during the installation. But now, when i am trying to test a .dev domain with a ping this is what i am getting :

MBP:~ anthony$ ping hhh.dev ping: cannot resolve hhh.dev: Unknown host

Does anyone have the answer for this issue ? Thanks guys !
