Operating System Requirements: Mac OS X 10.7+ Description: This software provides Thunderbolt support for Sonnet's Presto Gigabit Pro PCIe card when used with a Mac mini installed in Sonnet's xMac mini Server PCIe 2.0 expansion system/1U rackmount enclosure.
Thunderbolt connectors need to be in close physical proximity due to the very high speed board layout requirements. Sonnet thought it important to put the connectors outside to give rear panel access to connect additional Thunderbolt devices.
