MacOS – internet connection sharing assigned IP

Setting the internet connection sharing is straighforward from the OSX preferences. So I set the sharing via the ethernet cable so that when I ifconfig, I see some new entry bridge100 that is has 192.168.2.1 IP .
Then I connected my pi via the ethernet. Now, I try to find the IP that is assigned to the PI but when I ping the subnet 192.168.2.*, I get nothing else but 192.168.2.1. However, I notice that the ethernet cable is using en5 interface but with no IP. Do I need to set a static IP to en5 ?
