Clearance No.: FTDI# 123
FTDI drivers may be obtained from the FTDI website.
There are two types of driver: VCP (Virtual COM Port) and D2XX (direct access).
2.1 Getting VCP
VCP creates a virtual com port on the MAC and allows applications that use the POSIX programming
interface to communicate with the device. This is effectively the same us using a legacy com port.
The download is a Disk Image (dmg) file at: http://www.ftdichip.com/Drivers/VCP.htm
Download the version relevant to your OS version.
Clicking the weblink starts a download.
Inside the FTDIUSBSerialDriver_v2_2_18.dmg there are 2 package files:
FTDIUSBSerialDriver_10_3.mpkg which is specific to OS X 10.3 (Panther)
FTDIUSBSerialDriver_10_4_10_5_10_6_10_7.mpkg which is specific to OS X 10.4 (Tiger), OS X 10.5
(Leopard), 10.6 (Snow Leopard), 10.7 (Lion) and 10.8 (Mountain Lion).
Inside the FTDIUSBSerialDriver_v2_3.dmg there is 1 package file:
FTDIUSBSerial.pkg is suitable for OS X 10.9 (Mavericks) and later.
2.2 Getting D2XX
D2xx uses FTDI’s programming interface to access advanced features of the chips.
The download is a Disk Image (dmg) file at http://www.ftdichip.com/Drivers/D2XX.htm
The current version at the time of writing (version 1.2.2) covers all versions of OS X from 10.4 onwards.

3 Installing Drivers
3.1 Installing VCP Drivers on OS X 10.3 to OS X 10.8
To install the driver on the MAC you simply click on the .mpkg that matches your version of OS X.
With Lion and Mountain Lion, you will need to bypass the new Gatekeeper security function to install the
pkg file. Simply press Cntrl-Click when you select FTDIUSBSerialDriver_10_4_10_5_10_6_10_7.pkg.
This will bring up a pop-up menu. Select Open from this menu:
The following pop-up will appear:
Select “Open” and the VCP driver install process will begin ( see next page).
