In order to perform a "clean install" of Lion -- on a new hard drive or when restoring a machine to sell it, for example -- users will need to install Snow Leopard first, according to an email forwarded to MacRumors, purportedly from Apple CEO Steve Jobs. We have inspected the raw header information included in the email and believe it to be genuine, but these emails must always be taken with a grain of salt. And Steve's typically short response: If this is true, it seems likely Apple will continue to sell Snow Leopard for the foreseeable future for users upgrading from Leopard and to perform clean installs. Apple still sells Leopard for users who wish to upgrade their pre-Intel PowerPC Macs. Leopard is $129 and only available through 800-MY-APPLE, not the Apple Online Store or the retail stores. The company could offer Snow Leopard in the same surreptitious manner. Article Link: Lion Clean Install Requires Snow Leopard Disk?
