I followed all of the step in the link that Phoenixfire suggested but not all of them worked and I am still having trouble.
Looks like you skipped a few commands if that was the entire terminal?
Not using Mac myself but I'm fairly sure you were meant to run these one by one too.
touch ~/.bashrc
echo "export CFLAGS=\"-arch x86_64\"" >> ~/.bashrc
echo "export ARCHFLAGS=\"-arch x86_64\"" >> ~/.bashrc
source ~/.bashrc
brew update
brew doctor
After that it looks like you've got openssl 1.1 rather than 1.0. droark suggests this:
brew reinstall https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb
As for the "Downloading and Verifying Armory" steps you've got a typo.
gpg --recv-keys --keyserver eyserver.ubuntu.com 4922589A
should be
gpg --recv-keys --keyserver keyserver.ubuntu.com 4922589A
Another typo later on with the asc file - in the next command it doesn't look like you downloaded that file from step 4 as well.
This doesn't look like an offline install so just use copy and paste for each line instead of typing them out
