Getting started
1. Start your Mac and make sure you have an active Internet connection.
2. Plug your magicJack into your Mac.
Note: On Mac Mini, please do NOT use the USB port on the keyboard.
Your magicJack needs to be plugged into the port on your computer or into a powered USB hub.
3. Mac OS will recognize your magicJack device and mount its drives. Two drive icons will appear on your desktop.
4. Depending on the OS version and settings, a window may open with the instructions to run magicJack by clicking the magicJack icon. If it does not open, please double-click the mounted “magicJack” drive.
5. In the displayed window, double-click the large magicJack icon.
Note: Do not unplug your magicJack without dismounting its drives first. To dismount the drives, select the icons of the drives on your desktop and drag them into the Trash Can on the bottom right corner.
Troubleshooting
On Leopard, magicJack and/or other programs hang when I attempt to dismount the drives
Please unplug the magicJack. If this does not help, please reboot your computer.
magicJack is not visible in the system (the drives do not mount)
Please check if the OS version is supported. If it does, please check that the magicJack is not plugged into a keyboard port or passive hub.

Please unplug your magicJack and plug it back in after a few seconds.
