It's ridiculous that when you download an image file to run a node, eg raspiblitz....img.gz, a Mac will automatically unzip the download and throw the original in the trash. You are then left with raspiblitz...img and when you hash it you'll get the wrong hash. Because you're hashing the extracted (wrong) file. You have to take the original out of the trash and has that.

What’s ridiculous is you want to check a file hash but don’t know how to change settings on your mac.
Use tar instead
Is this safari? Pretty sure there is a setting to disable this
