OSX is a file format used by Mac OS X operating system. OSX files contain a header for compiled PowerPC applications that run on RISC processors. These PowerPC applications were run using Rosetta, a software emulator available for Mac OS X. Rosetta is no longer supported by Apple.
OSX files and Rosetta emulator were supported in Mac OS X 10.4, 10.5, and 10.6. Newer versions of Mac OS not only remove Rosetta from the program list, but also prevent it being installed.
An OSX file contains a program header for a Power PC application saved in the PEF (PowerPC Executable Format) binary executable format. It can run directly in Mac OS X on PowerPC-based Macintosh computers or via Rosetta on Intel machines. OSX files may also reference other files required for the program to run.
Programs that support OSX file extension can be encountered on all system platforms, including mobile, yet there is no guarantee each will properly support such files.
Common issues related to files with OSX extension can be resolved by the users themselves quickly without an IT expert.
