Hi All, Yesterday I got a FTDI (UART to USB) board from unknown manufacturer. I plugged in to the iMac and without a surprise, it was not working. I have tried all the possible combinations, but no luck. Then after some digging in Apple documentation and Google about kext, FTDI and related, I finally made it. Here are the steps: 1. In order to disable the AppleUSBFTDI.kext extension (From Mac OS X 10.8 there is Apple driver implementation for the FTDI chip). Cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns sudo mv AppleUSBFTDI.kext AppleUSBFTDI.disabled 2. Downloading and installing. Install the driver. Optional you can check if it is there and loaded. ![]() ![]() Ls -ld `/System/Library/Extensions/FTDIUSBSerialDriver.kext` kextstat| grep FTDI 4. Run system_profiler -detailLevel full in order to find device details with a plugged in FTDI board. Adobe photoshop free install download. “idVendor” = 0x403 “idProduct” = 0x0 “bcdDevice” = 0x600. My changes in Info.plist/IOKitPersonalities / FT232R USB UART 6. Now with the changes, signature of the driver is not correct so you need to turn on kext dev mode in the OS. Sudo nvram boot-args=”kext-dev-mode=1″ Reboot 7. Unload/Load the driver. You can skip this step if you just rebooted. It can be use when you do changes in the info file. Sudo kextunload /System/Library/Extensions/FTDIUSBSerialDriver.kext/ sudo kextload /System/Library/Extensions/FTDIUSBSerialDriver.kext/ 8. Plug in the FTDI to USD board and if you are lucky, you will see something likes this: ls /dev|grep usbserial cu.usbserial-A9GBBDLL tty.usbserial-A9GBBDLL Hope it helps.
