Transitive Technologies Power Rosetta

News.com confirms that Transitive Technologies is, in fact, the technology behind Apple's Rosetta PowerPC Emulator for their upcoming Intel-based Macintoshes.

Jobs reportedly confirmed Transitive's role in a New York Times interview, but in general, Apple has been very quiet about their Transitive's role in Rosetta. Of note, Jobs' keynote speech on Monday gave no mention to the startup.

It appears Transitive's technology can provide 60-80 percent performance of native software based on real world experience with SGI. Some analysts, however, have doubts about the performance promises.

First mention of Transitive came in July 2003. The most accurate and earliest rumor about Transitive's use by Apple came as a Page 2 news item in February 2005:

...there is evidence that Apple has had special internal seeds of Tiger which support [Transitive's technology] for the x86 platform. Beyond allowing Tiger to run on x86, perhaps more significantly is the potential to also allow existing Mac OS X applications to be run on the x86 (PC) platform without recompilation.


Apple, of course, is not offering Mac OS X for the PC, but instead offering Intel-based Macs.

Man I was wondering about this.Now I know..

So we're seeing the Transitive at work in this "transition"

So is QuickTransit/Rosetta a chip or a piece of software?

Old news... I already said this four days ago.

I think most people that are regulars here already knew (or had a good bet on it) this was the way they would switch to intel.

I wonder what type of performance we will see after a year of further development and tweaking on the part of Apple and Transitive. We may see near-full performance using Rosetta when it ships.

One thing I have been thinking about is this, Steve said that they would probably have the first Intel based Macs ready to show and probably sell by WWDC 2006 but Leopard is not going to ship for some time after that. So, I am wondering what version of Mac OS X will be shipped on these Macs. Is much of the software needed for the Intel based Macs already present in Tiger? Or will Apple be shipping a new version of Tiger that can be installed on either the PowerPC platform or the Intel platform.

i could be wrong, but doesnt this seem like its only a minor hack away from being able to put OSX on any old PC. i dont know how to do it myself, but it seems like once the switch to intels is made, it wouldnt me to hard for someone to manipulate their PC to accept and run OSX, any thoughts?

i seriosuly doubt that this will work, only a limited number of hardware configurations will work and apple will be the only ones supplying them

i think macs running on intel will have a different chipset, something like altivec or equivalent or some other propietary chip that will add funtionality and make it "different" than normal wintel machines... it will also make difficult to run plain windows from the box on them...

There are some Darwin folks over on ars.technica involved in porting Darwin to other chipselts, and according to them, it's far from a minor hack.

Some people dismiss that, but I would think practical experience would trump web board BSing....

The current "reported" performance of around 805% is pretty darn impressive, I sincerely doubt that they'll be able to tweak it much more that that.

Steve also said that OS X has been "leading a double life". They've had it running on Intel for the last five years, so I figure most of the code is already in ther, and just needs to be "activated". Hopefully a Software Update (restart required, natch) will do the trick.
