I've flashed my Google Coral Dev Board going through the instructions on this page:
<https://coral.withgoogle.com/docs/dev-board/get-started/#requirements>

I've downloaded the mendel development tool with 

```
    pip3 install --user mendel-development-tool

```

But when I try to connect to the board's shell via MDT, using

```
    mdt shell

```

I'm met with 

```
    mdt: command not found

```

I'm using a macOS, for reference. Any advice on whether I've downloaded MDT correctly, or am missing something else is greatly appreciated.
