Macintosh bootable volumes are supported on the internal 2-port PCI card (part number TSATA) but are not supported on any of the other SATA cards at this time.
Failure to power off a Tempo card before ejecting it may have an unpredictable result for OS X.
You should follow these steps:
1. Unmount any drives attached to the Tempo card by dragging them to the Eject icon in the dock.
2. Click the Card's icon in the menu bar and select "Power Off Card" from the drop down menu.
3. Push and release the Tempo card to eject.
