Mac OS X Tiger build 8R4061a

Mac OS X Tiger build 8R4061a is a build of Mac OS X Tiger 10.4.10. It was only bundled on early models of the late 2007 MacBook Pro, 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. It is present on restore discs for the machines, however. Critically, this build features kernel support for later models of Core 2 processors.
