Rosetta is arguably one of the most important pieces of software Apple ever shipped, and the tale of how it came from a British startup with a unique, powerful technology is rarely sung as a UK tech industry success story. Here we talk to the CTO and co-founder of that company to find out how it happened.
Rosetta is the software that allowed Apple to make a shift that resulted in it opening Macs up to a much wider market by switching from the PowerPC processors it had used before to Intel chips which, crucially meant Macs could dual-boot to run Microsoft Windows much more effectively than before – a big selling point for customers considering a switch to Apple computers. Intel’s processors had lower power consumption too, leading to longer battery life on laptop computers.
Rosetta was unveiled when Steve Jobs announced the switch to Intel processors in June 2005. Billed as “The most amazing software you’ll never see,” Rosetta allowed apps designed for PowerPC processors to run on Intel-powered Macs. That was no mean feat – this kind of translation took serious technical expertise but without it, Apple would have faced a serious backlash from users whose apps would be rendered obsolete the second they upgraded to an Intel-powered Mac.
