How can I verify the SHA256 hash of 0.10.3 “Wolfram Warptangent” on macOS?

Question

How can I verify the SHA256 hash published for the official 0.10.3 "Wolfram Warptangent” release matches the file that I downloaded for macOS, 64-bit?

Answer 1

On macOS:

1. Downloading the tar.bz file. I will assume it is located in the normal "Downloads" directory, and it's name is monero-mac-x64-v0.10.3.1.tar.bz2. Other names/locations are fine but you'll have to adjust the process accordingly.
2. Open Terminal. Easiest way is ⌘+spacebar and type "Terminal", then hit enter.
3. Change to the Downloads directory. Type cd ~/Downloads and hit enter.
4. Get the Sha-256 Checksum. Type shasum -a 256 monero-mac-x64-v0.10.3.1.tar.bz2 and hit enter.
5. Compare it with the checksum on the Monero page.

On Linux (tested on Ubuntu 16.04) the command is sha256sum rather than shasum -a 256.

On Windows, the command is pinch nose, scrunch eyes, and hope everything is good as you unzip the file. Just kidding. I don't know the Windows command though.
