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:
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.
