apters designed to work with Mini DisplayPort, such as adapters for DVI and VGA displays, still work with
Thunderbolt ports. Unfortunately, devices designed for Thunderbolt do not work with Mini DisplayPort con-
nectors.

The fourth- and fifth-generation MacBook Airs come with a Thunderbolt port for connections to external displays and
other devices.

Thunderbolt supports
daisy-chaining,
which means a single port can support multiple devices,
up to six at a time. This works because many Thunderbolt-compatible devices come with multiple Thunderbolt
ports. For example, take a look at the rear of the Promise Pegasus R4 RAID storage unit, shown in Figure 1.2.
As you can see, it includes two Thunderbolt ports. This means you can run a Thunderbolt cable from your Mac
to the device, and then run a second cable from the other Thunderbolt port to another device.
