Setup for macOS

To connect with the server we will download, install and configure:

• A server access key, which serves as a kind of password for logging in to the server.
• FileZilla, an open source file transfer application. This provides a drag and drop interface for transferring files between the server and your laptop.
• Terminal, a built-in Apple utility which provides a command line interface for UNIX operating systems

Having done so, we will prepare a workspace and will be ready to make art.

#Prepare your workspace
You'll be sharing the server with other workshop participants, To keep everyone's work seperate you've been assigned a username.

Find your user folder in FileZilla

The contents of the server are listed in the panel on the right. The top section of that panel shows the directories on the server, the lower section shows the contents of the selected directory. By default, you start in the root folder. We can navigate from here to your user folder

1. in the lower panel, double-click the users directory
2. double-click the folder with your username

Inside your user folder you will see 2 folders. The pictures folder contains the images that neural-style works with. The server renders its output to the temp folder. Note that pictures inside the temp folder tend to be overwritten, so it's always a good idea to save pictures you want to keep to your laptop.

Copy the pictures folder to your laptop

It's easier to review and manage pictures on your laptop than on the server. We'll work with pictures locally and upload any changes or new material to the server.

Find your user folder in the Terminal

In FileZilla you may have noticed a few files in your user folder in addition to the pictures and temp folders. These are rendering scripts. To start painting a picture you must type the name of these files into a Terminal window, but first you will need to point the terminal to your user folder

1. Click anywhere inside the Terminal window to make it active
2. Type this command: cd users
3. Type this command, and replace USERNAME with the username you were given 'cd USERNAME` for example, if your username is tiger, you should type: 'cd tiger'
4. Now the the following command, this will list the contents of your user folder: 'll'
