Download Mac Os Sierra From Windows

Whether you want to occasionally examination a website in Safari, or try out a niggling bit of software in the Mac environs, having access to the latest version of macOS in a virtual machine is useful. Unfortunately, you're not really supposed to do this—so getting macOS running in VirtualBox is, to say the least, catchy.

Update: The instructions here apply to older versions of macOS. If you lot want to install a newer version of macOS in VirtualBox, check out this script on GitHub. It promises to have yous through the process of installing and setting up a macOS virtual automobile. We haven't yet tested it ourselves, but we've heard good things.

It's not impossible, however. Some of the folks at theInsanelyMac forums have figured out a process that works. The only thingnot working is sound, which for some reason is highly distorted or nonexistent. Other than that, though, this is macOS High Sierra, running smoothly in VirtualBox.

To make things a lilliputian easier for people, we've combined methods from a few different forum threads into a single, footstep-by-step tutorial, complete with screenshots. Allow's dive in.

Notation: In order to get this working, y'all volition need access to a real Mac in guild to download High Sierra. Yous could, we suppose, obtain a High Sierra ISO by other ways, simply we don't recommend it. Infringe a friend's Mac for an hour if you don't have ane, and you lot should be fine—everything beyond step i of this tutorial tin can be done on your Windows PC.

If you're on a Mac and want a macOS virtual motorcar for employ on that Mac, nosotros recommend checking out out Parallels Desktop Calorie-free instead, because information technologytin create macOS virtual machines for complimentary and is a lot easier to work with.

Ready to go started? Let'southward jump in!

Step One: Create a macOS High Sierra ISO File

To offset, we'll need to create an ISO file of macOS High Sierra's installer, and then we can load information technology in VirtualBox on our Windows motorcar. Grab your borrowed Mac, caput to the Mac App Store, search for Sierra, and click "Download."

When the process is washed, the installer will launch—that's okay, just shut information technology with Command+Q. We don't want to upgrade your friend's Mac; we merely need the downloaded files.

To catechumen those files to an ISO, we'll demand to use the Terminal, which you can notice in Applications > Utilities.

Start, run the post-obit control to create a blank disk image:

hdiutil create -o /tmp/HighSierra.cdr -size 7316m -layout Spud -fs HFS+J

Next, mount your blank image:

hdiutil attach /tmp/HighSierra.cdr.dmg -noverify -nobrowse -mountpoint /Volumes/install_build

At present yous're going to restore BaseSystem.dmg from the installer over to the newly mounted image:

asr restore -source /Applications/Install\ macOS\ High\ Sierra.app/Contents/SharedSupport/BaseSystem.dmg -target /Volumes/install_build -noprompt -noverify -erase

Note that, after doing this, the name of our destination mount betoken has changed to "Bone Ten Base System/Organization." You're virtually done! Unmount the epitome:

hdiutil detach /Volumes/Bone\ X\ Base\ System

And, finally, convert the image you created into an ISO file:

hdiutil convert /tmp/HighSierra.cdr.dmg -format UDTO -o /tmp/HighSierra.iso

Motion the ISO to the desktop:

mv /tmp/HighSierra.iso.cdr ~/Desktop/HighSierra.iso

And you've got a bootable Loftier Sierra ISO file!

Copy it to your Windows machine using a large flash drive, an external hard drive, or over your local network.

Pace Two: Create Your Virtual Machine in VirtualBox

Adjacent, head to your Windows machine, and install VirtualBox if you haven't already, making sure you have the latest version (seriously, older versions may not work.)

Open it upwardly and click the "New" push button. Name your Virtual Car "Loftier Sierra," and choose "Mac OS Ten" for the operating arrangement and "Mac Bone X (64-bit)" for the version (as of this writing, "macOS High Sierra" is not offered, simply that's fine.)

Continue through the process. For retentivity, we recommend you employ at to the lowest degree 4096MB, though yous can opt for more if yous have enough RAM to spare on your Windows machine.

Next, you lot'll be asked about your hard drive. Choose "Create a Virtual Hard disk Now" and click Create.

Choose VDI for hard disk type and click Side by side. You'll be asked if y'all want a dynamically sized drive or fixed. We recommend Stock-still Size, since information technology's a bit faster, though information technology'll take up a bit more hard drive infinite on your Windows machine.

Click Next. You lot'll exist asked how big a drive you desire; we recommend at least 25GB, which is big enough for the Bone and a few applications. Depending on your storage state of affairs, you lot could offer more, but nosotros don't recollect you can really use much less than that.

Click through the prompts, and yous've created an entry for your virtual machine! At present it'due south fourth dimension to do a little configuration.

Pace Three: Configure Your Virtual Machine in VirtualBox

Yous should see your virtual auto in VirtualBox's primary window.

Select it, and then click the big yellow "Settings" button. First, head to "System" in the left sidebar. On the Motherboard tab, make sure that "Floppy" is unchecked.

Next head to the "Processor" tab, and make certain you have at least two CPUs allocated to the virtual motorcar.

Side by side, click "Display" in the left sidebar, and make certain Video Retentiveness is set to at to the lowest degree 128MB.

Next, click "Storage" in the left sidebar, then click the "Empty" CD bulldoze. Click the CD icon at the superlative correct, and then browse to the High Sierra ISO file you created earlier.

Exist sure to click "OK" to finalize all the changes you've made, and so close VirtualBox. No, seriously: shut VirtualBox at present, or the adjacent steps won't work.

Step Four: Configure Your Virtual Machine From The Command Prompt

We've made a few tweaks, but we need to make a few more more in order to convince the operating system it'southward running on a real Mac. Sadly, there are no options for this from VirtualBox's interface, so you'll need to open the Command Prompt.

Open the Start Carte, search for "Command Prompt," then right-click it and select "Run equally administrator."

Yous need to run a number commands, in order. Paste the following commands, pressing Enter after each 1 and waiting for it to complete:

cd "C:Program FilesOracleVirtualBox"

VBoxManage.exe modifyvm "Loftier Sierra" --cpuidset 00000001 000306a9 04100800 7fbae3ff bfebfbff

VBoxManage setextradata "High Sierra" "VBoxInternal/Devices/efi/0/Config/DmiSystemProduct" "MacBookPro11,iii"

VBoxManage setextradata "High Sierra" "VBoxInternal/Devices/efi/0/Config/DmiSystemVersion" "one.0"

VBoxManage setextradata "High Sierra" "VBoxInternal/Devices/efi/0/Config/DmiBoardProduct" "Mac-2BD1B31983FE1663"

VBoxManage setextradata "Loftier Sierra" "VBoxInternal/Devices/smc/0/Config/DeviceKey" "ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc"

VBoxManage setextradata "High Sierra" "VBoxInternal/Devices/smc/0/Config/GetKeyFromRealSMC" i

That'due south information technology! If everything worked, you shouldn't see any feedback; the commands volition only run. If the control did not work, make sure your virtual machine is named "High Sierra" exactly; if it isn't, edit the commands above putting your machine'due south name in the quotes. Become ahead and shut the Command Prompt. We're heading back to VirtualBox at present.

Step Five: Boot and Run The Installer

Re-open VirtualBox, click your Sierra machine, and so click "Beginning." Your machine will start to boot. You will encounter a lot of superfluous information every bit this happens—and I mean a lot—but don't worry about information technology. It's normal, even some of the things that look similar errors.

You should only worry if a specific fault hangs for five minutes or more than. Just walk away and let it run for a bit. If you lot've done everything correct, it'll kicking.

Eventually, you lot'll come across the installer request yous to selection a linguistic communication:

Pick "English language," or whatever linguistic communication y'all adopt, then click "Next." Before y'all do anything else, all the same, click "Deejay Utility" and so "Continue."

Yous won't run across the drive: don't panic, High Sierra hides blank drives by default. In the menu bar, click "View" followed by "Evidence All Devices."

Yous should at present see your empty virtual drive in the sidebar. Click it, then click the "Erase" option.

Name the bulldoze "Macintosh Hd," and leave the other ii settings as-is: "Mac OS Extended Journaled" and "GUID Sectionalisation Map". Practice not create an AFS partition, because it will not piece of work and you'll have to starting time over with a new virtual hard drive. Click "Erase," then shut Deejay Utility when the process is consummate. You'll be brought dorsum to the main window.

Select "Reinstall macOS" then click "Keep." You'll exist asked to concur with the terms.

Agree and you'll eventually be asked to choose a difficult drive; select the sectionalisation you just fabricated.

The installation will begin! This might take a while, and so exist patient. Eventually your virtual motorcar will restart and accept you…dorsum to the installer. Don't panic: this is to exist expected.

Step Half dozen: Boot Installer Stage Two From the Virtual Difficult Drive

At this point the installer has copied files onto the virtual hard drive, and expects to boot from there. For whatever reason this does not work on the virtual machine, which is why you're seeing the installer once again.

Turn off your virtual machine and open up its settings. Caput to Storage, click "HighSierra.iso" in the "Storage Tree" console, then click the CD icon at top-right and click "Remove Disk from Virtual Drive." This volition completely disconnect our installation ISO.

Now start up the virtual motorcar and you lot'll run across this lovely screen.

This is the EFI Internal Trounce, and every bit long as yous encounter "FS1" listed in yellow, y'all tin can use it to launch the rest of the installer. Click the virtual machine and allow information technology to capture you mouse and keyboard, and so blazon fs1: and hit Enter. This will switch directories to FS1, where the rest of the installer is located.

Next nosotros're going to run a few commands in order to switch to the directory we need:

cd "macOS Install Data" cd "Locked Files" cd "Kick Files"

At present nosotros can run the installer itself with the post-obit control:

boot.efi

The installer will pick up where it left off. First you'll encounter a series of text, like before, but eventually you'll see the GUI installer come back. (Don't worry, yous only have to go through this procedure once.)

We're getting there, but need a little bit more than patience.

Step Eight: Log Into macOS High Sierra

Eventually the virtual machine volition reboot again, this fourth dimension into macOS High Sierra. If that doesn't happen, try ejecting the ISO from the Virtual Machine. When High Sierra does kick, y'all'll need to go through choosing your state, setting up a user, and the rest of the initial setup process.

Eventually, you'll make information technology to the Mac desktop. Yay!

Yous tin can now endeavour out any Mac software, though some functions, similar FaceTime and Letters, won't piece of work considering Apple won't recognize your figurer as a existent Mac. Just a lot of the basic stuff should work. Have fun!

Step Viii (Optional): Change Your Resolution

By default, your virtual machine will accept a resolution of 1024×768, which is not a lot of room to piece of work with. If you endeavor to change the resolution from inside macOS, however, yous will see no option to do so. Instead, you lot need to enter a few commands.

Shut downward your Virtual Automobile by shutting downwards macOS: click the Apple tree in the carte bar, then click "Shut Down." Adjacent, close VirtualBox entirely (seriously, this step will not piece of work if VirtualBox is withal open!) and head back to Windows' Control Prompt every bit an admin. You demand to run the following two commands:

cd "C:Program FilesOracleVirtualBox"

VBoxManage setextradata "High Sierra" "VBoxInternal2/EfiGopMode" Due north

In the second command, you need to replace the N with a number from one to five, depending on what resolution you want:

1 gives yous a resolution of 800×600
2 gives you a resolution of 1024×768
3 gives yous a resolution of 1280×1024
4 gives yous a resolution of 1440×900
five gives you a resolution of 1920×1200

Outset up VirtualBox, load up your virtual machine, and it should boot to your preferred resolution!

From now on, you can open VirtualBox for whatsoever Mac-related testing you desire to do. Again, you'll encounter a lot of errors pop up during boot, but they're fine; ignore them. Also, remember that audio won't piece of work, nor volition things like FaceTime or iMessage, which crave a real Mac. This isn't going to exist perfect, which is to be expected from an entirely unsupported setup. But it's macOS, in a virtual machine, and that'southward not bad! Exist sure to check out our guide to VirtualBox'south advanced features to go the virtually out of your machine, too.

I more affair: a huge shout-out to Republic of chad South. Samuels, without whom I could not take updated this guide for High Sierra. Thank you so much!
