Parallels update brings memory enhancements
Parallels (a virtualization solution for OS X) users that own Mac Pros or the new Intel iMacs will want to download the latest Parallels release (as will most other Parallels users). Why am I specifying the Mac Pro and the Intel iMac? Well, Parallels had a nasty little problem with being able to access all the RAM on those systems. A number of hacks had to be put in place in order to get things working properly, but no more.
The latest update addresses the RAM issues on the 64 bit Macs, as well as introducing support for Leopard as a primary OS, and official Vista support. The rest of the enhancements can be seen here.
