Mac OS Download Page
To download the 8.3 Client for Mac OS X (Universal Binary) click here.
This will begin the download of the installer. When the download completes, the installer will automatically be decompressed by a decompression program such as "Stuffit Expander" or Apple's "Disk Utility."
At the end of this step you should have a new item on your desktop called "FC8325US.dmg". You may also have a new icon on your desktop called "InstallFirstClassClient8325" containing one item named "Install FirstClass Client". Double-click on this and follow along the install prompts.
When the Login screen appears, simply enter your user ID and password and click Login.
NOTE: We strongly discourage saving your password.
Saving passwords usually results in a forgotten password, and it will allow anyone with access to your computer to login to your account. Please do not click "Save" when there is a password (displayed as asterisks) entered into the password field.
If you have difficulty with this installation, you can reach technical support at 207.772.7250.
