Installation Instructions for FirstClass Online Client 16.109 for Mac OS X

NOTE: In order to install FirstClass Client you will need the access privileges of an Administrator account.

1. Let us start by double clicking the following link if you have not yet downloaded the client:

Double client on the downloaded disk image so that the client "disk" will be mounted on the desktop and you will see a window with the "Install FirstClass Client" installer.  Double click on the installer to begin.

2.  Installation Screens

a. Introduction - The first screen is a splash of the FirstClass logo. Click Continue.
b. License - click Continue. A dialog box will appear asking you to agree to the terms of the software license agreement. Click Agree.
c. Installation Type - Leave it set to "Easy Install" and click Install.
d. Installing - the installing screen now appears and the software is installed.
e. Finish Up - click Quit.


We will now need to configure the FirstClass Client by filling in some information into the FirstClass Login screen.

1. If the FirstClass Client is not automatically launched, click the FirstClass icon now on your desktop to start the program. Now you should see the FirstClass Login window.

a.      Click the "Advance Tab" on the bottom left to expand the FirstClass Login screen. Locate the "Address" field.  This should be set to "home.fc".  If it is not, using the pulldown menu to the right of this field select home.fc.
b. Now click on the Setup button located on the right side of the Login Screen. This will open a window called "Service Setup". You will need to make the following changes:
* Set Connect via to the following
High-Speed Internet.FCP” - regardless of your connection type
* Type into the "Server" field.  Please take care to type this correctly with no spaces before or after.
* Set Encryption to CAST-128.

After doing this click the button Save. Below is how the “Service Setup” will look like for a “High-Speed Internet.FCP” setting.


2. Now enter your User ID and Password that was provided to you into the User ID and Password fields of the FirstClass Login screen.  If you are in a Western Nation and you are using a computer at your home, you may now click "Save" to keep your user id and password.  Your password is scrambled for security reasons, this is why it gets longer when saved.  Anyone outside of a Western Nation should NEVER save their password. Now, while connected to the Internet, click "Login".

3. If this your first time using FirstClass or CAST-128 encryption, you will be prompted to save the encryption key, as seen below. Click Accept.


Your FirstClass Desktop window should open!
