Thank you, I overlooked the mention of clicking back to the Download page for the verification links.
Ran the steps, however working out the following errors now:

Code:

Mac:Downloads macUser$ ls
Bitcoin-Qt.app SHA256SUMS.asc
SHA256SUMS bitcoin-27.0-x86_64-apple-darwin.zip
-snip-
shasum: bitcoin-28.0-x86_64-apple-darwin.zip: No such file or directory
bitcoin-28.0-x86_64-apple-darwin.zip: FAILED open or read

Since you've downloaded the older version Bitcoin Core v27.0, you should also download the "SHA256SUMS" and "SHA256SUMS.asc" file for that specific version.
You can find it in their previous releases link: https://bitcoincore.org/bin/bitcoin-core-27.0/

It wont fix the "Unknown option: ignore-missing" error though since it looks like an issue with your OS and shasum.
At least, ignore the obviously missing file results since you haven't downloaded those.
