- USB works (mouse, keyboard, headset, USB 3.0 flash drive)
- 1920x1200 monitor output works via 3rd-party DisplayPort->DVI adapter (haven't tried direct HDMI)
- 1920x1080 monitor output works via direct HDMI and 3rd-party DisplayPort->HDMI adapter
- Port multiplier eSATA works (tried 2 volumes)
- Ethernet works (1000BaseT auto negotiated properly with my router)
- S/PDIF stereo works (PCM)
- Have not managed to get S/PDIF multichannel passthrough to work (it seems the Mac needs a USB multichannel passthrough enabler). Might be ready to work on a Hackintosh.
- Does not like being unplugged and replugged to the computer (screens constantly redetecting, needs reboot to connect external monitor again)
This was with Yosemite 10.10.3 on 17" MBP Early 2011 (Thunderbolt 1)
