(October 2015) The Apple–Intel architecture, or Mactel, is an unofficial name used for Apple developed and manufactured by that use processorsrather than the and processors used in their predecessors. With the change in architecture, a change in became necessary; Apple selected the Intel-designed Extensible Firmware Interface (EFI) as its comparable component to the Open Firmware used on its PowerPC architecturesand as the firmware-based replacement for the PC from Intel. With the change in processor architecture to, Macs gained the ability to boot into x86-native operating systems (such as ), while brought near- with Mac OS X as the host OS. Main articles: and With the change in architecture, a change in became necessary. Extensible Firmware Interface (EFI) is the firmware-based replacement for the PC from Intel.

Designed by Intel, it was chosen by Apple to replace, used on architectures. Since many operating systems, such as Windows XP and many versions of Windows Vista, are incompatible with EFI, Apple has released a firmware upgrade with a compatibility support module that provides a subset of traditional BIOS support with their product. GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical hard disk.

It is a part of the Extensible Firmware Interface (EFI) standard proposed by Intel as a substitute for the earlier PC BIOS. The GPT replaces the Master Boot Record (MBR) used with BIOS. Booting To Mac operating systems Intel Macs can boot in two ways: directly via EFI, or in a 'legacy' BIOS compatibility mode. For, holding down 'Option' gives a choice of bootable devices, while the is commonly used for added configurability. Standard cannot be used on Intel Macs; the EFI firmware can recognize and boot from USB drives, but it can only do this in EFI mode–when the firmware switches to BIOS mode, it no longer recognizes USB drives, due to lack of a BIOS-mode USB driver.

Many operating systems, such as earlier versions of Windows and Linux, can only be booted in BIOS mode, or are more easily booted or perform better when booted in BIOS mode, and thus USB booting on Intel-based Macs was for a time largely limited to, which can easily be booted via EFI. To non-Mac operating systems. Mac Mini with Intel Core On April 5, 2006, Apple made available for download a public version of, a collection of technologies which allows users of Intel-based Macs to boot Service Pack 2. The first non-beta version of Boot Camp is included in, 'Leopard.'

Before the introduction of Boot Camp, which provides most hardware drivers for Windows XP, drivers for XP were difficult to find. can also be booted with Boot Camp.

Differences to standard PCs Intel-based Mac computers use very similar hardware to PCs from other manufacturers which ship with or operating systems. In particular, and are entirely compatible. However, Apple computers also include some custom hardware and design choices not found in competing systems:. is a custom Apple chip that controls various functions of the computer related to, including handling the power button, management of battery and thermal sensors, among others. It also plays a part in the protection scheme deployed to restrict booting macOS to Apple hardware (see below). Laptop input devices. Early and computers used an internal variant of as a and interconnect.

Since the 2013 revision of, Apple started to use a custom controller instead. The additionally uses a custom internal USB device dubbed 'iBridge' as an interface to the Touch Bar and components, as well as the. PC laptops generally use internal variant of the legacy keyboard interconnect. PS/2 also used to be the standard for PC laptop pointing devices, although a variety of other interfaces, including USB, and, may also be used.

Additional custom hardware may include a GMUX chip that controls, non-compliant implementations of and non-standard configurations of subsystem. has significant differences between. While PC keyboards can be used in, as well as Mac keyboards in, some functional differences occur.

For example, the (PC) and ⌥ (Mac) keys function equivalently; the same is true for ⊞ (PC) and ⌘ (Mac) – however, the physical location of those keys is reversed. There are also keys exclusive for each platform (e.g.

), some of which may require software remapping to achieve the desired function. Compact and laptop keyboards from Apple also lack some keys considered essential on PCs, such as the, although some of them are accessible through the key. Boot process. All Intel-based Macs have been using some version of as the boot firmware. At the time the platform debuted in 2006, it was in a stark contrast to PCs, which almost universally employed legacy, and Apple's implementation of EFI did not initially implement the that would allow booting contemporary standard PC operating systems.

Apple updated the firmware with CSM support with the release of in April 2006, and since the release of in 2012, has required its partners to use UEFI boot process on PCs, which made the differences smaller. However, Apple's version of EFI also includes some custom extensions which are utilized during regular macOS boot process, including:. A driver for the with support locating the bootloader based on the 'blessed directory' and 'blessed file' properties of HFS+ volumes. The is thus not used or necessary for regular macOS boot process. Rudimentary pre-boot GUI framework, including support for image drawing, mouse cursor.

This is used by to present the login screen before loading the operating system. Other non-standard EFI services for managing various firmware features such as the computer's and boot arguments. Some of these differences can pose as obstacles both to and booting alternative operating systems on Mac computers – Apple only provides for its custom hardware for and (as part of ); drivers for other operating systems such as need to be written by third parties, usually volunteer enthusiasts. Digital Rights Management in the Apple–Intel architecture is accomplished via the Dont Steal Mac OS X.kext, sometimes referred to as DSMOS or DSMOSX, a file present in Intel-capable versions of the. Its presence enforces a form of, preventing Mac OS X being installed on stock PCs.

The name of the kext is a reference to the Mac OS X license conditions, which allow installation on Apple hardware only. According to Apple, anything else is Mac OS X. The kext is located at /System/Library/Extensions on the volume containing the operating system.

The extension contains a kernel function called pagetransform which performs decryption of 'apple-protected' programs. A system lacking a proper key will not be able to run the Apple-restricted binaries, which include Dock, Finder, loginwindow, SystemUIServer, mds, ATSServer, backupd, fontd, translate, or translated.

After the initial announcement of first Intel-based Mac hardware configurations, reporting a among system components, it was believed that the TPM is responsible for handling the DRM protection. It was later proven to not be the case.

The keys are actually contained within the, a component exclusive to Apple computers, and can be easily retrieved from it. These two 32-byte keys form a human-readable ASCII string copyrighted by Apple, establishing another possible line of legal defence against prospective clone makers. Virtualization.

(October 2015) The (and later, including the current i5, i7 and Xeon) processors found in Intel Macs support, allowing for high performance (near native), which gives the user the ability to run and switch between two or more operating systems simultaneously, rather than having to dual-boot and run only one operating system at a time. The first software to take advantage of this technology was, released in June 2006.

The Parallels virtualization products allow users to use installations of Windows XP and later in a virtualized mode while running OS X. Is virtualization software from, which was released January 2007. Available for Mac OS X as well as other host operating systems, it supports and can run multiple other guest operating systems, including Windows XP and later. It is available free of charge under either a proprietary license or the license and is used by default when running images of other operating systems offers a product similar to Parallels calledreleased August 2007. VMware's virtualization product also allows users to use installations of Windows XP and later under OS X. Regardless of the product used, there are inherent limitations and performance penalties in using a virtualized guest OS versus the native Mac OS or booting an alternative OS solution offered via Boot Camp.

Advertisement Installing While Mac OS X works well for most tasks, there are times when it just can't do what you want it to. More often than not this means running Windows on your Mac., but did you know you can install macOS on a PC? It’s not a project for those who don’t like to get hands-on with hardware, but with the right combination of components and effort, it is possible. In order to It's really easy to save the macOS installer to avoid multiple downloads, and worth doing even if you only have the one Mac., you’re going to need to use another Mac to Microsoft offers a simple tool to create a bootable USB on Windows, but there is no such tool for Mac users.

Fortunately the process is pretty easy, if you know how. You’ll also need access to the Mac App Store to download macOS in the first place.

So let’s take a look at how it’s done. Before You Begin Back in the day (, to be precise), this tutorial explained how to install (what was then) Mac OS X on a Windows PC without the need for a Mac. This is no longer possible with modern versions of macOS.

Apple strictly forbids the use of macOS on any machines other than its own, whether it’s a modified version or not. You should be aware that by doing this, you’re violating the terms of the macOS license agreement, and that you do so at your own risk. If you have an older PC, you’ll be pleased to know you can install every version of macOS (or OS X) from 10.7.5 Lion right up to 10.12 Sierra. Whether or not your older machine will be compatible is another story entirely.

It's official, updating my hackintosh/getting it to work is officially the most frustrating thing I've ever done — Alex Walling (@AlexWalling) It’s worth reiterating that installing macOS on a non-Apple computer is hard work. You may encounter hardware problems, card readers and Wi-Fi might not work, and you’ll need to go the extra mile if you want to use features like iMessage or audio-over-HDMI. Things You’ll Need To install the latest version of macOS on your PC, you will need:.

a PC with compatible hardware. a Mac running the latest version of macOS. the. free apps.

an 8GB or larger USB drive. patience Don’t worry if you’re unsure about anything on the list, we’ll explain these requirements in the steps below. If you haven’t got a Mac, ask to borrow a friend’s for a few minutes (you won’t need it for long, though make sure you get the root admin password). Ensure Your PC is Compatible The best way to ensure compatibility is to build your machine to specification. By doing this you’ll be using hardware that’s the same or very similar to what Apple puts in its own machines. You’ll be able to build a high powered machine for a fraction of the cost of a new Mac. Alternatively, you may want to install macOS on a laptop or PC that you already have lying around.

This route is harder, you might have to work around issues that arise, or you may have incompatible hardware. Feelin' proud– just finished an almost one-week quest to turn a $100 used Dell into an 'iMac'. — WS (@shortwill) Assuming you’re currently running Windows, you can download free app to get a Even if you’re not overly geeky, you probably have a rough idea of how much memory and what sort of processor your computer has.

But what about its other statistics? For example, do you know. You can then use the following resources to ascertain compatibility. — a well-maintained resource for hardware components and pre-built laptops and desktops that play nicely with macOS. — a constantly-updated “shopping list” for building macOS compatible computers in a variety of form factors. Online forums — check out, and Hackintosh Zone No Longer Available if you want to ask questions or search for builds similar to your own. Download Your Software Once you’re confident your machine is compatible, grab your Mac and launch the Mac App Store.

Search for the latest version of macOS and hit Download. The file is around 4.7GB in size, and once downloaded appears as Install macOS Sierra in your Applications folder. Leave it there for now. Next head to and register an account, which will grant you access to the. From here you should download the latest version of UniBeast. At the time of writing is designed purely for Sierra, while previous versions work with earlier editions of the OS.

You should also download the version of MultiBeast that corresponds with your macOS version. For macOS Sierra, this is.

You can unzip it and leave it in your Downloads folder for now, we’ll need it later. UniBeast is a tool for installing any legally downloaded version of macOS from the Mac App Store on compatible hardware. It can also be used as a Mac (or hackintosh) system recovery tool in a pinch. Extract UniBeast and Switched to a Mac and getting to grips with the basics? Wondering how to install software from the command line? Got old Windows apps that you simply must run on your Apple computer? By dragging it to your Applications folder.

Create Your USB Installer Insert the USB drive you’ll be using into your Mac and launch your Mac’s in-built Disk Utility application. Everything on the drive — including the partition itself — will be removed so make sure your data is safe before proceeding. When you’re ready, select your USB device in the list on the left and click Erase. Give it a name and choose Mac OS Extended (Journaled) under “Format” and GUID Parition Map under “Scheme” then click Erase.

Your USB device is now ready to become a bootable macOS installation drive. Launch UniBeast and follow the prompts — you’ll have to click Continue about four times, then Agree with the software license agreement (above). When you’re prompted for an install destination, select the USB drive you erased with Disk Utility (below). The installer will now prompt to choose the version of macOS you downloaded from the Mac App Store earlier (below). For this to work the Mac App Store download needs to have finished and the Install macOS Sierra file should stay in your Applications folder.

Next you’ll need to choose Bootloader Options (below). According to the UniBeast documentation, choose UEFI Boot Mode for UEFI-capable systems (most modern hardware) or Legacy Boot Mode for older machines that still use BIOS ( Sometimes when troubleshooting, you'll need to know whether your PC uses UEFI or BIOS. Here's how you can check with ease.). The penultimate step is to choose a graphics card manufacturer if you’re using an older card (this step is optional).

You can then click Continue, make sure your settings are correct, enter your admin password, and UniBeast will write the macOS installer to the drive. Wait for the image to be written to the USB drive. The last thing you need to do is to copy MultiBeast to the root directory of your USB drive. Install macOS on Your PC Now you’re ready to begin installing macOS on your PC. Turn on your PC and press and hold the Delete (or equivalent) key to bring up your UEFI or BIOS settings. This is where things get a little tricky — the recommends the following:. Set BIOS/UEFI to Optimized Defaults.

Disable your CPU’s VT-d, if supported. Disable CFG-Lock, if supported. Disable Secure Boot Mode, if supported. Disable IO SerialPort, if present. Enable XHCI Handoff.

Disable USB 3.0 UEFI/BIOS settings are a common cause for issues when trying to install macOS. You’ll probably need to hit the forums if you experience issues here, as each manufacturer does things a little differently. Save and exit once you’ve configured your BIOS/UEFI, then power the machine off. Insert the USB installer we created earlier into your PC, preferably into a USB 2.0 port. Power on your PC and while it boots press the boot device keyboard shortcut — probably F12 or F8. When prompted, choose your USB drive, then on the Clover boot screen select Boot Mac OS X from USB.

The installer will now launch, and you’ll first need to select a Language. As you’ll be installing macOS from scratch, you need to prepare the installation volume.

Click on Utilities at the top of the screen and open Disk Utility. Choose your target destination for macOS, then click on the Erase button. Give it a name (e.g Hackintosh), choose OS X Extended (Journaled) under “Format” and GUID Parition Map under “Scheme” then click Erase.

You can now continue with the installer, making sure you choose this disk when prompted for an installation location. That's right — nick.js (@npsmith90) Assuming it all goes to plan, you should be able to see the installer through to the end at which point your Mac will restart. 5. Finishing Touches Now you’ll need to make your Mac install partition bootable, so you’re not depending on the USB bootloader. Restart your machine and hold down the boot device select key (probably F12 or F8), then boot from your USB device as you did last time. At the Clover boot screen, select your installation volume (e.g. Hackintosh) and follow the instructions to finalize the macOS installation. When you eventually boot into macOS, navigate to your USB installer and run the MultiBeast app.

For fresh installs, click on Quick Start and choose between UEFI Boot Mode or Legacy Boot Mode (for older hardware), then select relevant audio and network options on the Drivers tab. You can see even more options under Customize before saving or printing your chosen configuration. Now hit Build then Install. If you’re using unsupported NVIDIA hardware, now is the time to and install them. The final step is to restart your Hackintosh and remove your USB drive, as your macOS installation partition should boot automatically from now on.

Now the Fun Begins There are so many things that could go wrong with this process. It’s unlikely you’ll make it all the way without a small snag or larger setback, and at the end of it all you’ll still need to fiddle with things to get some features working the way you’d like. If things aren’t quite working for you, hit up the relevant forums for advice tailored to your predicament. You can also try the comments below. Have you ever built a Hackintosh? Did it go well?
