Mac OS X Tiger build 8R4031 is a build of Mac OS X Tiger 10.4.10. It was only preinstalled on the Mid-2007 iMac, as the machine was announced prior to the release of Mac OS X Leopard but was released six days after the release of that OS on 1 November 2007, leading to an awkward transitional period. Unlike other builds in this category, it wasn't shipped on restore DVDs. Instead, build 8R4088 was shipped. Critically, this build features kernel support for Penryn models of Core 2 processors.
