invalid file when downloading bitcoincore

[onefocus]

Hello everyone!
I am downloading a file from the official website bitcoincore.org wallet for Macbook. I download by clicking in the browser.
The file is downloaded .tar instead of tar.gz!
after checking (shasum -a 256 --ignore-missing --check SHA256SUMS) the output is: no file was verified!
Then I do the command shasum -a 256 and it gives me a sum that is not in the SHA256SUMS file. You can see everything in the photo.
What could it be?
How is this possible?

Hiding the file extension sounds like a Windows thing to do.

Then I do the command shasum -a 256 and it gives me a sum that is not in the SHA256SUMS file.

If it's a different file, the different checksum is no surprise. What link did you download?
Link from the site: https://bitcoincore.org/bin/bitcoin-core-28.1/bitcoin-28.1-x86_64-apple-darwin.tar.gz
If I download this, I get the correct checksum from your screenshot. If I gunzip the file, the remaining .tar file produces the same checksum you got. Any chance you have a browser extension that extracted the file?

So your browser extracted it. That's the only possibility, so it's a Mac problem, not a Bitcoin problem.

MacOS will automatically unzip .gz and .zip files.

In that case: maybe bitcoincore.org should add hashes for the uncompressed .tar for apple files to SHA256SUMS. I'm not sure though how that would work for the .zip, if that instantly produces a directory structure with files.
