network workflow and productivity will remain uninterrupted as they migrate
to Apple's new operating system. This is what sets Group Logic apart - our

competitors and innovations within the industry."

ExtremeZ-IP 5.1.1 has undergone extensive testing with the new Mac Leopard
platform. In addition to maintenance changes that ensure the product is
certified for the new Mac OS X Leopard 10.5, ExtremeZ-IP version 5.1.1 also
incorporates a number of other enhancements including improvements to
Unicode compatibility.
