How to check md5 and Sha356 values on MAC OS.
Open Terminal.
Navigate to the folder that contains the file whose MD5 checksum you want to verify.
You can open Terminal right at a folder from Finder.
Type md5 followed by the filename:
md5 <file>
Dragging and dropping: You can also type md5, then drag and drop the file you want to check onto the Terminal window.
How to Check SHA-256 on macOS
Open the Terminal app by searching for it in Spotlight (Cmd + Space) or via Launchpad.
Type the command below, making sure to add a space after 256:
shasum -a 256
Drag and drop your file directly from Finder into the Terminal window to automatically fill in the correct file path.
Press Enter to run the command and generate the hash.
