FTDI releases signed drivers for Yosemite
FTDI has released new signed drivers for OS X 10.10 Yosemite. Although Apple now includes their own FTDI driver with OS X, many have reported issues using some older or unusual FTDI-based USB devices. Hopefully, these new drivers will solve any existing issues, and will allow users running older non-signed drivers to avoid having to run in development mode.
The new signed FTDI drivers can be downloaded here.
