Now X is designed for:
• Intel-based computers
• 2G of RAM
• Mac OS X 10.5 Leopard
Because Now X is designed to take advantage of newer technologies, we recommend an Intel processor with two gigabytes of RAM. Minimum system requirements are PPC-based computers with 1G of RAM. Now X runs on both Mac OS X 10.4 Tiger and Mac OS 10.5 Leopard.
Public beta for Windows XP and Vista is in development and will have similar hardware requirements.
