LogicielMac publishes a screenshot for the system requirements for Mac OS X Snow Leopard which was seeded to developers this week. The requirements list the following:
- An Intel Processor
- An internal, external, or shared DVD drive
- At least 512 MB of RAM
- Display connected to an Apple-supplied video card
- 9GB of disk space, or 12GB for developer tools
Developers received an early copy of Snow Leopard at WWDC this week. As this is an early version, requirements could change in the future, but the dropping of PowerPC support has been long rumored. MacRumors can independently verify that these are the current requirements for Snow Leopard.
