I don't know if this the best route, but right now when I try to install
the kinematic-beta I'm told the checksum doesn't match:
```
❯ brew cask install kinematic-beta
==> Downloading https://github.com/docker/kitematic/releases/download/v0.12.0/Kitematic-0
==> Verifying checksum for Cask kinematic-beta
==> Note: running "brew update" may fix sha256 checksum errors
Error: sha256 mismatch
Expected: 161d702e25cfda4337c5f9b1315ad1487b287cd581e8951caee7ff529595370c
Actual: 0d6770197ed1db1c9a653c78bc51bb0d1483882233cf2d2bf688609b1a5251ef
File: /Users/andrew/Library/Caches/Homebrew/Cask/kinematic-beta--0.12.0.zip
To retry an incomplete download, remove the file above.
```
I snagged the value via a direct download of kitematic from GitHub:
```bash
curl -sL https://github.com/docker/kitematic/releases/download/v0.12.0/Kitematic-0.12.0-Mac.zip \
| shasum -a 256
```
