Universal Apps Intel Macs By the end of 2006 Apple had switched its entire Macintosh product line over to Intel s Core Duo processors the successor to the Pentium . Yes that Intel. The company that Mac partisans had derided for years as part of the Dark Side. The company that Steve Jobs routinely belittled in his demonstrations of PowerPC chips which IBM and Motorola supplied to Apple for more than a decade . The company whose marketing mascot Apple lit on fire in a 1996 attack ad on TV. Why the change Apple s computers can only be as fast as the chips inside them and the chips that IBM had in the works just weren t keeping up with the industry. As one editorial put it Apple s doing a U-turn out of a dead-end road. And sure enough Intel-based Macs start up and run much faster than the old Macs thanks to the endless march of speed improvements in the chip-making world. And thanks to that Intel chip today s Macs can even run Microsoft Windows and all of the thousands of Windows programs. Chapter 8 has details. At the time though there was a small glitch Existing Mac software didn t run on Intel chips. Apple would have to ask the world s software companies to rewrite their programs yet again after already having dragged them through the Mac OS 9-to-Mac OS X transition only a few years earlier. Fortunately the transition wasn t as gruesome as you might expect. First Apple had already secretly recompiled reworked Mac OS X itself to run on Intel chips beginning with Mac OS X . Furthermore Apple wrote an invisible translation program code-named Rosetta which permits the existing library of Mac OS X programs Photoshop Word and so on to run unmodified on Intel Macs. They do not however run especially fast on Intel Macs. In fact many of them run slower than they did on pre-Intel Macs. To make their programs perform at full speed on Intel-based Macs programmers have to update their wares. All the big software companies promised to make their programs into .
