Some articles that might help (or hinder):

This one is Ubuntu specific and you can't make your own spin of Zorin:

I am wondering if your Mac cannot use the home wifi band i.e. is limited to 2.4GHz and your home wifi is 5GHz.
Just a thought, as we have seen a user affected by this previously.

I checked out the first article Default txpower is 31dBm and is unable to connect in Ubuntu 20.04
And after running the command:

sudo iwconfig wlp2s0 txpower 10dBm

The wifi instantly connected

Does it stick after reboot or do you have to run the command again?

No, I have to re-enter the command after reboot, I'm sure that can be automated with crontab or something

This complex solution for increasing dBm might help you in reverse.

That is irrelevant in this case as Apple Silicon processors were only announced in 2020:

The Macbook used by enate is from 2017

Basically my solution is to run the command:

sudo iwconfig wlp2s0 txpower 10dBm

every time I boot up the machine, if your looking a stable device to run ZorinOS don't go with Mac, I'm also having issues with built-in speakers.
