Can the iPhone 8 run Mac OS ? With the A11’s power?

    With geekbench scores already higher than the MacBook Air’s
    I believe the iPhone 8 is more than able to run MacOS with a lightening to display port.

    It definitely can, but they're not going to. At least not yet. iOS is starting to become more macOS like though, which is apparent with iOS 11.

    Processing power is only one small part of the equation

    With a dongle hub. It already has super fast SSD and power.

    I am looking forward to the A11X in next years iPad Pro. Much less thermal throttling. And the ability to use HMP heterogeneous multiprocessing. And a faster clock and a 12'Core or More GPU I always thought the purpose of the iPad Pro was to run Mac OS. With optional Keyboard.

    Now that iPad Pro prices are at a Delta with MacBook Air prices. Just sell us a $899 OLED iPad Pro with 1 USB-C port and Dual Boot option MacOS or iOS. And Keep MacBook Airs at $799

    iOS uses the XNU Mach 2.5 derivative that underlies Darwin, the Open Source BSD Unix variant.
    Mac OS X is the base off of which iOS is designed.
    Obviously, the kernel was ported to ARM type processors. This is not difficult given that Mach was designed for heterogeneous environments (processor agnostic/independent).

    Your iPhone and iPad run an optimized Mac OS X, using Cocoa (CocoaTouch) and Darwin BSD.
    Both Mac OS Sierra and iOS 10 are running Darwin 16.0.

    For all intents and purposes, it already is.

    However, you mean the actual Mac OS with its full libraries and APIs.

    Let's benchmark the slowest machine Apple lists on its updateable list as the lowest possible requirements.
    High Sierra will be used as the benchmark.

    This, of course will be the Macbook Air 11 Inch in Late 2010.

    1.4GHz Intel Core 2 Duo processor with 3MB on-chip shared L2 cache; or optional 1.6GHz Intel Core 2 Duo processor with 3MB shared L2 cache

    800MHz frontside bus
    2GB of 1066MHz DDR3 SDRAM onboard (4GB maximum)

    Now, let's look at the iPhone 7 (not the Plus)
    Quad-core (2× Hurricane + 2× Zephyr) 2.34 GHz max clock on Hurricane. Zephyr assumed anything below that.
    L1 cache Per core: 64 KB instruction + 64 KB data
    L2 cache 3 MB shared
    L3 cache 4 MB shared

    Although ARM chips used to be severely underpowered versus their mobile and desktop variants, you can still compare based on pure computational scores.
    Daring Gruber gives us this info.

    The iPhone 7 (not the Plus) outperformed the Macbook Air 2015 in single core score but was in a technical tie on multicore scores (the MacBook Air 2015 barely beat it).

    Therefore, the iPhone 7 is capable of running the full Mac OS X, Darwin/Mach/Cocoa and all of their full desktop APIs, calls, and plug-ins.

    I hope this answers your questions.

    Would need a lot more memory and all sorts of different other chip support

    The A11 cannot run Mac OS X because the architecture does not support it.

    The A11, and all other common mobile processors use ARM architecture. Mac OS X was originally designed to run on Power PC architecture, but now runs on Intel x86 processors found in other consumer PCs.

    If Apple wanted OS X to run on the A11, they would need to have to rewrite the OS to be compatible with ARM. It was originally said that iPhone OS is the spiritual successor of Mac OS X for mobile devices.

    It could if were ported to ARM, it has enough power. I just don't really see the point and Apple would never do it. I could see an ARM MacBook at some point though.

    That is my eventual dream machine...where the iPhone is a portable hub that can plug into a desktop workstation and be a full desktop machine, or even sell a laptop/tablet shell with larger screen and keyboard options. When they kept touting the change to 64 bit processors as having desktop computing power, I thought maybe they were heading in that direction. Would love to have 1 ultra-portable computer (my phone) that can be used as the base for different form factor workstations.

    I can't remember, but I think there is an old video of Steve Jobs imagining this very thing. Hopefully they keep that same spirit.

    Most of MacOS is written in high level language (C++ or such) and would not be a huge job porting it to ARM and I would not be surprised if Apple already has something in their hidden labs. If you are programming in low level such as assembler it would be more difficult though.

    iOS is Mac OS X. It is the same codebase. Plus, they would not have to rewrite the entire OS.
    The Kernel of both iOS and Mac OS is designed for heterogeneity. Mac OS X was Intel ready from Mac OS 10.0 Beta

    It took them 7 months to transition Mac OS X from Power PC to Intel because Mac OS X was ALREADY compiled for x86.
    And since iOS is Mac OS X at its core, it would take Apple little under a year to compile and port for two reasons:
    1. iOS has ten years on ARM. So, not too hard to figure out how to work on ARM
    2. They design ARM processors, unlike their PCs that use third party vendor chips.
    Will not be hard, and half their work is already done.

    They should just integrate USB-C with host capabilities and a trackpad with multi-touch gestures.
    No other change needed, seriously.
    Obviously I'm talking about the iPad, not the iPhone.

    Wasn't there information on Apple testing macOS in an A5-powered MacBook Air?
