I have tried everything, from nmap to AngryIP scanner to PiFinder and i cannot find the IP address. How could I go about this using a complete and total headless method - because on top of it all the HDMI to HDMI cable that I'm using doesn't work to display anything, and I can't use my MacBook as a display until I get the IP address in order to use Screen Sharing. Below is my last attempt. I need help I am really struggling. And I am a beginner to RPi stuff.

$ ping raspberrypi.local ping: cannot resolve raspberrypi.local: Unknown host

From your description I do not think the networking is alive, else nmap would've found it.

Just to make sure you can run nmap with the following options -A 192.168.1.0/24 (where 192.168.1.0/24 is your own network) The /24 will scan each host from 192.168.1.0 to 192.168.1.255.

If it doesn't show up on the nmap scan, then I sincerely doubt that it even has networking running.

May I ask how you set up your PI before you connected the ethernet cable?

My preferred method is to do an install with HDMI so that you see what is going on and only when you have networking fully enabled to go into an ssh method for management.

Check if you have properly formatted the SD card in FAT32 format and that the raspberry pi is able to detect the SD card. If the green LED glows continuously just after power on then your SD card may not have been detected properly. Once you know see that the green LED blinks then you can confirm that your pi is able to boot. You can follow this tutorial to do a headless install https://www.youtube.com/watch?v=1pGSnPgYYrU . Once the installation is complete, use port scanners or check your router to get the IP address.

If it is your only Pi on the network and it is on the same subnet, you could try an fping to the complete work (fping -g -r 1 192.168.0.0/24; replace the 192.168.0.0/24 with your subnet). And then do an arp -a. The Pi will probably have a mac-ID starting with B8-27-EB, DC-A6-32 or E4-5F-01. The arp -a will list the associated IP address.
