How to Verify downloads with SHA checksum using macOS

 

Step 1: 

Download file from official site or repository and ensure to get the corresponding SHA checksum

For reference, we will be using the following

Downloaded filename : name_of_downloaded_file

Downloaded file's checksum : sha_checksum_of_downloaded_file

Step 2:

Open Terminal

Step 3: 

Run the following command in the Terminal from the directory where file was downloaded

> echo "sha_checksum_of_downloaded_file" *name_of_downloaded_file | shasum -a 256 --check

Step 4: 

Check output or response after executing above command. You should get similar output as below

name_of_downloaded_file: OK

Step 5: Done.

Example (taken from Ubuntu site - https://ubuntu.com/download/server)

> echo "f8e3086f3cea0fb3fefb29937ab5ed9d19e767079633960ccb50e76153effc98 *ubuntu-20.04.3-live-server-amd64.iso" | shasum -a 256 --check

ubuntu-20.04.3-live-server-amd64.iso: OK
