(2) An emulator from Apple that ran PowerPC-based applications on Intel-based Macs under OS X. Included with Apple's first Core Duo-based laptops, Rosetta ran most OS X applications except for those that used specific instructions in the G5 processor. Named after the Rosetta Stone, which inscribed a decree in 196 BC of the Egyptian King Ptolemy V in three languages, the Rosetta emulator was discontinued in the Lion version of Mac OS X. See Mactel.
