Sometimes you just need to have a new MAC address on your computer.

Open up Terminal on MAC and use the below command to see which interface is in use (with an IP to your connected network), for me, it's en0

We can checkout current mac address using the following command:

ifconfig en0 |grep ether

Type the following command to randomly generate a new mac address:

openssl rand 6 | xxd -p | sed 's/\(..\)/\1:/g; s/:$//'

And then to change your mac address, replacing the x's with the mac address you just generated:

sudo ifconfig en0 ether xx:xx:xx:xx:xx:xx

We can check to see if it's worked by checking our mac address again:

ifconfig en0 |grep ether

Now we recommend to disable and enable your connected interface (For wireless, turn it off and on and for ethernet, pull the cable out and put it back in)
