Apple Another Apple-to-switch-Macs-to-ARM post. "Apple engineers have grown confident that the chip designs used for its mobile devices will one day be powerful enough to run its desktops and laptops, said three people with knowledge of the work, who asked to remain anonymous because the plans are confidential. Apple began using Intel chips for Macs in 2005." No idea when Apple will make the switch, but they will do it. I'm thinking 5-10 year timeframe.

"...but you already have a iOS device emulator for Mac OS X... for 5 years now.

they (Apple) do not even call it "emulator" but rather "simulator" (since there is nothing to emulate! e.g. ARM ;) )

Not sure what you meant by "since there is nothing to emulate" followed by a winky face, but if your comment was meant to be tongue-in-cheek, sarcastic, or ironic somehow, note that there literally is nothing to emulate. Apps built in Xcode for the simulator are built as x86 targets, not for ARM.
ok, let's elaborate this:

if you need emulator: that mean that you need to emulate ARM CPU on intel Macs.

if you have "simulator": that is meant that you do not need to emulate ARM CPU because all code (frameworks) are compiled for Macs x86 and you still have iOS apps & OS itself running on x86 CPU without emulating ARM.

EXACTLY as you said:

Apps built in Xcode for the simulator are built as x86 targets, not for ARM.

there is no need to emulate ARM.

back to first topic: there is no need to switch Mac to ARM just to be able to run iOS Apps!
