Thunderbolt is a revolutionary I/O technology that supports high-resolution displays and high-performance data devices through a single, compact port. It dramatically redefines the idea of expansion. And it’s standard on every Mac.

http://www.apple.com/thunderbolt/[11/17/13, 6:11:44 PM] Apple - Thunderbolt: Next-generation high-speed I/O technology.

On every new Mac, Thunderbolt technology gives you access to a world of high-speed peripherals and high-resolution displays via one simple port and a cable that carries both DisplayPort and PCI Express data.

Now with Thunderbolt 2 built into the new Mac Pro and MacBook Pro with Retina display, you can connect the latest 4K desktop displays and get double the bandwidth for your peripherals. And the two generations of Thunderbolt technology are compatible with each other.

http://www.apple.com/thunderbolt/[11/17/13, 6:11:44 PM] Apple - Thunderbolt: Next-generation high-speed I/O technology.

PCI Express is the technology that links all the high-performance components in a Mac. And it’s built into Thunderbolt. Which means you can get PCI Express speed outside the box. With Thunderbolt, your external devices like RAID arrays and video capture solutions become hot‑pluggable and easy to move between your Mac computers.

http://www.apple.com/thunderbolt/[11/17/13, 6:11:44 PM] Apple - Thunderbolt: Next-generation high-speed I/O technology.

Thunderbolt gives you two channels on the same connector with 10Gb/s of throughput in both directions. Ultrafast, ultraflexible Thunderbolt 2 pushes that to 10Gb/s Channel 20Gb/s. You can move data to and from peripherals up to One 20 times faster than with USB 2 and up to 12 times faster10Gb/s Channel

than with FireWire 800. You also have more than enough ThunderboltTwo

bandwidth to daisy-chain multiple high-speed devices 5Gb/s without using a hub or switch. For example, you can connect several high-performance external disks, a video USB 3 capture device, and even a display to a single 2.5Gb/s Thunderbolt chain while maintaining maximum ExpressCard throughput.

800Mb/s Expansion is no longer confined by the space inside your FireWire 800 Mac. Now you can plug in your PCI Express cards using a

Thunderbolt chassis. You can even connect more than 480Mb/s

one chassis together to plug in many more cards than USB 2 you could in a computer with a finite number of expansion slots. With PCI Express technology, you can use your USB and FireWire peripherals — and connect to Gigabit Ethernet and Fibre Channel networks — using simple adapters.

http://www.apple.com/thunderbolt/[11/17/13, 6:11:44 PM] Apple - Thunderbolt: Next-generation high-speed I/O technology.

Thunderbolt 2 gives you access to the latest 4K monitors. In fact, with the Mac Pro, you can connect up to three 4K displays at once. And because Thunderbolt is based on DisplayPort technology, it provides native support for the Apple Thunderbolt Display and Mini DisplayPort displays. DVI, HDMI, and VGA displays connect through the use of adapters.

If you’re a video editor, imagine using a single port to connect high-performance storage, a 4K display, and high-bit-rate video capture devices to handle all the post- production for a feature film. Thunderbolt I/O technology allows you to daisy-chain up to six Thunderbolt peripherals, including an Apple Thunderbolt Display and the Promise Pegasus 2 RAID or LaCie 2big disk. *

http://www.apple.com/thunderbolt/[11/17/13, 6:11:44 PM] Apple - Thunderbolt: Next-generation high-speed I/O technology.

And with Thunderbolt standard on every Mac, you can easily share high-performance peripherals among your Mac computers. You can even use a Thunderbolt cable to create a fast 10Gb/s link between Mac computers, thanks to IP over Thunderbolt support in OS X Mavericks.

All that power and blazing-fast data transfer flows through the Apple Thunderbolt Cable, one of the most advanced cables ever made. No single cable has been able to do so many things and do them with such astonishing speed. It doesn’t just connect high-performance devices. It is one in its own right. Thunderbolt also provides double the power of USB 3, delivering 10 watts to peripherals like external solid-state drives for improved performance on the go. And with cables available in lengths from half a meter to 30 meters, there’s plenty of room to grow.

15. How many Apple Thunderbolt Displays can I use with a Mac in Windows 7 or 8 with Boot Camp?

You can use only one Apple Thunderbolt Display with Windows 7 or 8 with Boot Camp.

16. Can I connect a Mini DisplayPort display to my Apple Thunderbolt Display for computers that support using more than one display?

Mini DisplayPort displays will not function if connected to the Thunderbolt port of an Apple Thunderbolt Display. Displays connected via Mini DisplayPort video adapter or cable to the Thunderbolt port of an Apple Thunderbolt Display will not work.

17. Can I use an Apple Thunderbolt Display and an iMac in Target Display Mode to act as two additional displays for my Thunderbolt-equipped Mac?

Yes. If your Thunderbolt-equipped Mac supports two Thunderbolt displays this is possible. Your Thunderbolt- equipped Mac will need to be connected to your Apple Thunderbolt display and the iMac will need to be connected to the Thunderbolt port of the Apple Thunderbolt display. Once connected, place the iMac into Target Display Mode to enable it as the second external display.

Notes:

Make sure the Thunderbolt Display is connected to your Thunderbolt-equipped Mac and is being recognized and used by the Thunderbolt-equipped Mac before connecting the iMac to the Thunderbolt display. If the iMac is placed in the Thunderbolt chain before the Apple Thunderbolt Display, the Thunderbolt display will work as an external display for the iMac and it will stay active as an external display for the iMac, but it will not function with the main Thunderbolt-equipped Mac using the iMac's display. To use an iMac in Target Display Mode when connected to an Apple Thunderbolt Display, the iMac must be Thunderbolt-enabled, and a Thunderbolt cable must be used (not a mini-DP cable).

18. Can I connect a Mini DisplayPort monitor or monitor using a Mini DisplayPort adapter to a Thunderbolt port on my Thunderbolt-equipped Mac?

Yes. A Mini DisplayPort display or a display connecting with a Mini DisplayPort to VGA, DVI, or HDMI adapter will work just like it was connecting to a Mini DisplayPort connector when plugging in directly to the Thunderbolt connector on your Apple computer. Click here for more information on Mini DisplayPort connections and adapters.

19. How do I connect my Mini DisplayPort monitor or monitor using a Mini DisplayPort adapter to my Thunderbolt-equipped Mac when I have other Thunderbolt devices connected?

When connecting a Mini DisplayPort display or a display using a Mini DisplayPort adapter to a Thunderbolt peripheral (except as described in question 14), make sure the display is connected at the end of the Thunderbolt chain. You can use only one Mini DisplayPort device in the Thunderbolt chain.

Note: Systems with more than one Thunderbolt port, like an iMac, can have more than one Mini DisplayPort monitor or monitor connected with a Mini DisplayPort adapter connected as each Thunderbolt port can support one Mini DisplayPort display.

20. Can I connect my Mini DisplayPort monitor or monitor using a Mini DisplayPort adapter to my Apple Thunderbolt Display?

Mini DisplayPort Monitors or Monitors connecting with Mini DisplayPort adapters will not function when connected through a Thunderbolt Display. They must be connected directly to the Thunderbolt port on the computer or to a non-display device as indicated above.

21. Why isn't my device recognized when I plug it directly into the Thunderbolt port when running Windows 7 or 8 via BootCamp?

Windows 7 and 8 scans and activates devices connected to the Thunderbolt port only during the startup process. If a device isn't connected when the computer starts up, Windows will not recognize the device. Restart the computer with the device connected to the port. Thunderbolt devices may also need a driver when running on Windows 7 or 8.

22. Can I plug and unplug devices (Hot Plug) into a Thunderbolt port under Windows 7 or 8 via BootCamp?

No. To add Thunderbolt devices, shut down the computer, connect the new devices, and then boot to Windows

23. My Macintosh running Windows 7 or 8 does not sleep when a Thunderbolt device is plugged in. Is this normal?

Yes. Sleep is disabled in Windows 7 or 8 while a Thunderbolt device is plugged in.

24. Can I use Target Display Mode or Target Disk Mode with Boot Camp and Windows 7 or 8 using a Thunderbolt-capable iMac?

No. Target Display Mode and Target Disk mode are not supported using Boot Camp and Windows 7 on a Thunderbolt-capable iMac.

25. If I eject a Thunderbolt device using the Taskbar tool or disconnect the Thunderbolt cable, can I

http://support.apple.com/kb/HT5219[11/18/13, 12:05:12 PM] Thunderbolt ports and displays: Frequently asked questions (FAQ)

reconnect it again without restarting?

No. A directly-connected Thunderbolt device that is removed with the Taskbar tool or by disconnecting the Thunderbolt cable will not be recognized until you restart the computer.

26. Do Thunderbolt devices stay connected if my Mac hibernates?

If the battery in your portable Mac is depleted enough to cause your portable to hibernate, all Thunderbolt devices will be disconnected. After connecting to power and waking the system, restart your computer to reconnect your Thunderbolt devices.

27. Why doesn't the ExpressCard I insert into my MacBook Pro ExpressCard slot seem to be recognized while I'm using Windows with Boot Camp?

"Plug and Play" with ExpressCard does not work while a Thunderbolt device is connected to your MacBook Pro. Disconnect or eject the Thunderbolt device to use your ExpressCard slot.
