Intel transition to be easiest in Apple history

First indications from Mac developers point to a quick and smooth transition to the Intel platform. In fact, this transition could be "the easiest of all those yet experienced by Apple developers," according to a report by RedNova. "The most difficult part about it is switching to Xcode, which is something that we'd be doing anyway," said Chuck Rogers of MacSpeech. For those who have already made that transition, the Intel switch promises to be painless. Because Apple has prepared well for the move to Intel, developers are expecting relatively few problems. "They had the OS up and running for so long," said Rich Siegel of Bare Bones, "and because the fundamental architecture of the OS is different -- everything is abstracted -- it's much easier to adapt your code for a new CPU architecture because the OS really protects you from all that."

My little telescope controller app is written with Cocoa in XCode and recompiled and ran without a hitch as a universal binary the first time. A friend tested it for me at WWDC on one of the developer transition machines.

The proof of the pudding is in the eating – right now I don’t really care how good the cooks say it is.

From a consumer standpoint, I don't remember the transition from 68000 processors to PPC being all that difficult. Didn't the PPC processors have 68k emulation?

The emulation was done in software, if I remember correctly.

Not exactly. Apple wrote emulator, which I believe was part of the ROM, because the emulator could also be used on system code, not just applications. Anyway, the emulator was completely transparent to both user and programmer. The emulator emulated the 68020.

...and everyone has already predicted the outcome!

It SHOULD be easy. As long as both processors are supported it should be easier than switching from Windows to Mac. It's Mac to Mac!

Oh yeah. G4 and G5 required code will take work. Oh well...

The emulator emulates the 68LC040, a low-power version of the 68040 that does not include hardware floating point.

Someone says it'll be painless. So we all know its going to be painless.

Well, unless your software requires Altivec. Or you're still running some Classic software because the company is out of business or no longer supports the mac. Or the peripheral maker decides not to make a driver for Intel.

But besides that....

The turtle worries a lot more than it needs to.

Existing PPC Macs won't stop running when the Intel-based Macs appear.

Apple will still be making PPC Macs for a while longer.

Even used Macs will still run, and can be had on the used market.

And most "altivec-enabled" software falls back on non-altivec code if it isn't running on a G4/G5 Mac. It's called degrading performance gracefully.

Irritating and annoying, some, painful, for a few, occasionally.

But keep on worrying; the sky may yet fall.
