While connecting a wired Elite trainer on PC is basically plug-and-play, on Mac you will need to download a driver for it to work:
- OSX 10.3 to 10.8: http://www.ftdichip.com/Drivers/VCP/MacOSX/FTDIUSBSerialDriver_v2_2_18.dmg
- OSX 10.9 and up: http://www.ftdichip.com/Drivers/VCP/MacOSX/FTDIUSBSerialDriver_v2_3.dmg
After you install that, Zwift should be able to see the trainer under both the Power and Controllable Trainer categories.
Some important notes about the functionality of wired Elite trainers:
- Some wired Elite trainers use a different protocol and aren't supported. Models manufactured after ~2006 should work, but if your trainer doesn't show up under Power or Controllable Trainer, we recommend contacting Elite to confirm that it's not a trainer compatibility limitation.
- ERG mode isn't supported on some of the older wired versions. As we're not sure when this feature was added in the product lifespan, we recommend contacting Elite to confirm this is an option on your trainer if you don't see the functionality available on the workout selection screen.
