Unfortunately for these people the latest security update has broken some aspects of Rosetta's functions, which is now causing their PowerPC applications to not work properly. Rosetta was available in OS X up until Snow Leopard but was left out of OS X Lion, a decision that forced a number of people to stay with Snow Leopard in order to continue using their PowerPC applications. This technology allowed for a relatively seamless transition to Intel CPUs in 2006, giving developers time to build native Intel versions of their programs.

Rosetta is a dynamic instruction translator for PowerPC code that allows PowerPC-based programs to run on Intel CPUs. Along with the OS X 10.7.3 update, Apple issued Security Update 2012-001 for Snow Leopard to address a number of security vulnerabilities in the latest version of that OS.Īfter installing the update, a number of people have found that Rosetta applications no longer work properly, and are reporting problems with applications crashing, no longer being able to perform tasks like saving files, or having problems with services like printing.
