Sonnet Technologies notes that its upgrade cards for Mac fully support Mac OS X v10.5 “Leopard.”
The company has given the thumbs up for Leopard for its entire expansion card family. That includes PCI Express (PCIe) cards for the Mac Pro, Xserve and Power Mac G5; PCI and PCI-X cards for the Power Mac G5 and Power Mac G4, ExpressCard/34 cards for the MacBook Pro, CardBus cards for PowerBook G4 laptops, and its line of Encore/ST and Encore/MDX processor upgrade cards for Power Mac G4 and Xserve G4 systems.
Sonnet notes that in some Power Mac G4 systems using Sonnet 1GHz to 1.8GHz processor upgrades, Leopard use may be possible — Apple says Leopard requires an 867MHz or faster G4 processor in order to work.
