For most users, this will not be a problem, as the 64-bit kernel of Snow Leopard only starts up by default only for Snow Leopard Server on 20 Xserves. However, VMware Fusion 2.0.5 is NOT compatible with the optional 64-bit kernel of Snow Leopard and Snow Leopard Server. The 64-bit kernel can be enabled optionally on a number of 2008, 2009 Macs In addition to the default Snow Leopard install, which is the 32-bit kernel with support for 32-bit and 64-bit applications, Snow Leopard now offers a 64-bit kernel option that is available by default for Snow Leopard Server on 20 Xserves. VMware Fusion 2.0.5 offers experimental support for the default install of Snow Leopard, which runs both 32-bit applications and the new faster 64-bit applications on the default 32-bit kernel. So, even though you are running the 32-bit kernel by default, the rest of Mac OS X Snow Leopard is running in 64-bit mode for better performance. According to Apple, all included Apple applications are now 64-bit for higher performance, but the default kernel for every Mac except the Xserve is the 32-bit kernel.

Just so you know, I’m writing this blog post in Windows XP virtual machine on an iMac running VMware Fusion 2.0.5 on Snow Leopard and it works great. Our initial testing of VMware Fusion 2.0.5 with the final release of Snow Leopard has gone very well, but we are still running our full suite of tests on the final Snow Leopard release just to be sure. However, there was always the minor chance that something could change before the final version of Snow Leopard. Of course, we kept up with the pre-release seeds of 10.6 and done a great deal of testing of VMware Fusion 2.0.5 and found that it worked well on the default Snow Leopard install (the 32-bit kernel which runs both 32-bit and 64-bit applications). Many VMware Fusion users have been wondering how VMware Fusion 2.0.5 fares on Snow Leopard, and we’re proud to report that VMware Fusion 2.0.5 now offers experimental support for the Snow Leopard when running the default 32-bit kernel!
