in mac rumors i read this:
- Mac OS X Lion requires a minimum of an Intel Core 2 Duo, leaving out compatibility for Apple's earliest Intel-based machines offering Core Solo or Core Duo processors.
this rumor abut that Lion would be 64 bit only.. and..
does it mean that quicktime and quartz will work in 64 bit mode?
and does it mean that all apps should be rewritten in 64 bit and VDMX too?
