On January 10, 2006, Apple released the first [[x86|Intel x86]]-based Macs along with the 10.4.4 update to Tiger. This operating system functioned identically on the [[PowerPC]]-based Macs and the new Intel-based machines, with the exception of the Intel release dropping support for the Classic environment.<ref name=":1" /> 10.4.4 introduced [[Rosetta (software)#Rosetta|Rosetta]], which translated 32-bit PowerPC machine code to 32-bit x86 code, allowing applications for PowerPC to run on Intel-based Macs without modification.
Only PowerPC Macs can be booted from retail copies of the Tiger client DVD, but there is a Universal DVD of Tiger Server 10.4.7 (8K1079) that can boot both PowerPC and Intel Macs.
