I recently bought an SSD for my old Apple computer. I updated the system from Snow Leopard to Yosemite as some applications requires a newer system.

Mac OS X now comes with drivers for FTDI-based USB serial ports. Unfortunately, if you plug in a JTAG adapter, such as Amontec JTAGkey, you will get a serial port but CrossWorks won't be able to access the JTAG part of the adapter. In order to correct this you must unload the FTDI drivers: sudo kextunload -b com.FTDI.driver.FTDIUSBSerialDriver. There is a different driver version for Mac 10.3-10.8 and Mac OS 10.9 and above. Make sure you select the proper one for your OS. When working with most of our FTDI products you are going to be using the FTDI as a 'Virtual Com Port' or VCP. This is important to note when looking at the FTDI driver download page.
Two weeks after I found that my FTDI chip (serial to USB converter) was faulty. Use another, same problem. After a quick loop with an oscilloscope, the reset signal was not good...
After a look on the internet, I found thah Apple now develops its own drivers but they which are faulty :/

So the workaround is to
- Disable Apple's driver by copy/pasting the following command in a terminal
- Reboot
- Install the driver from FTDI, which is signed in case you care about :)
