Rumors of an ARM-based MacBook Air are not new. In May, one report claimed that Apple had built a test notebook featuring the same low-power A5 processor found in the iPad 2. The report, which came from Japan, suggested that Apple officials were impressed by the results of the experiment.

via AppleInsider | Apple seen merging iOS, Mac OS X with custom A6 chip in 2012.

Following up on an article they did back on May 27th, and one prior to that on May 6th,  AppleInsider does a bit of prediction and prognosticating about the eventual fusion of iOS and Mac OS X. What they see triggering this is an ARM chip that would be able to execute 64-bit binaries across all of the product lines (A fabled ARM A-6). How long would it take to do this consolidation and interweaving? How many combined updaters, security patches, Pro App updaters would it take to get OS X 10.7 to be ‘more’ like iOS than it is today? Software development is going to take a while and it’s not just a matter of cross-compiling to an ARM chip from a software based on Intel chips.

Given that 64-bit Intel Atom chips are already running on the new Seamircro SM10000 (x64), it won’t be long now I’m sure before the ARM equivalent ARM-15 chip hits full stride. The designers have been aiming for a 4-core ARM design that will be encompassed by the ARM-15 release real soon now (RSN). The next step after that chip is licensed and piloted, tested and put into production will be a 64-bit clean design. I’m curious to see if 64-bit will be applied across ALL the different product lines within Apple. Especially when the issue of power-usage and Thermal Design power (TDM) is considered, will 64-bit ARM chips be as battery friendly? I wonder. True Intel has jumped the 64-bit divide on the desktop with the Core 2 Duo line some time ago and made them somewhat battery friendly. But they cannot compare at all to the 10 hours+ one gets on a 32-bit ARM chip today using the iPad.

Lastly, App Developers will also need to keep their Xcode environment up to date and merge in new changes constantly up to the big cutover to ARM x64. No telling what that’s going to be like apart from the previous 2 problems I have raised here. Apple in the 10.7 Lion run-up was very late in providing the support and tools to allow the developers to get their Apps ready. I will say though that in the history of migrations in Apple’s hardware/software, they have done more of them, more successfully than any other company. So I think they will be able to pull it off no doubt, but there will be much wailing and gnashing of teeth. And hopefully we’ll see something better as the end-users of the technology, something better than a much bigger profit margin for Apple (though that seems to be the prime mover in most recent cases as Steve Jobs has done the long slow fade into obscurity).

If ARM x64 is inevitable and iOS on Everything too, then I’m hoping things don’t change so much I can’t do things similarly to the way I do them now on the desktop. Currently on OS X 10.7 I am ignoring completely:

  1. Gestures
  2. Misson Control
  3. Launch Pad
  4. AppStore (not really because I had to download Lion)

Let’s hope this roster doesn’t get even longer over time as the iOS becomes the de facto OS on all Apple Products. Because I was sure hoping the future would be brighter than this. And as AppleInsider quotes from May 6th,

“In addition to laptops, the report said that Apple would ‘presumably’ be looking to move its desktop Macs to ARM architecture as well. It characterized the transition to Apple-made chips for its line of computers as a ‘done deal’.”
