Next head to the “Processor” tab, and make sure you have at least two CPUs allocated to the virtual machine. On the Motherboard tab, make sure that “Floppy” is unchecked. First, head to “System” in the left sidebar. Select it, then click the big yellow “Settings” button. You should see your virtual machine in VirtualBox’s main window. Step Three: Configure Your Virtual Machine in VirtualBox Depending on your storage situation, you could offer more, but we don’t think you can really use much less than that.Ĭlick through the prompts, and you’ve created an entry for your virtual machine! Now it’s time to do a little configuration. You’ll be asked how big a drive you want we recommend at least 25GB, which is big enough for the OS and a few applications.

We recommend Fixed Size, since it’s a bit faster, though it’ll take up a bit more hard drive space on your Windows machine.Ĭlick Next. You’ll be asked if you want a dynamically sized drive or fixed. Choose “Create a Virtual Hard Disk Now” and click Create.Ĭhoose VDI for hard disk type and click Next. Next, you’ll be asked about your hard drive. For memory, we recommend you use at least 4096MB, though you can opt for more if you have enough RAM to spare on your Windows machine. Name your Virtual Machine “High Sierra,” and choose “Mac OS X” for the operating system and “Mac OS X (64-bit)” for the version (as of this writing, “macOS High Sierra” is not offered, but that’s fine.)Ĭontinue through the process. Next, 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.)
Step Two: Create Your Virtual Machine in VirtualBox

Move the ISO to the desktop: mv /tmp/ ~/Desktop/HighSierra.isoĪnd you’ve got a bootable High Sierra ISO file!Ĭopy it to your Windows machine using a large flash drive, an external hard drive, or over your local network.
To start, we’ll need to create an ISO file of macOS High Sierra’s installer, so we can load it in VirtualBox on our Windows machine. Grab your borrowed Mac, head to the Mac App Store, search for Sierra, and click “Download.”Īnd, finally, convert the image you created into an ISO file: hdiutil convert /tmp/ -format UDTO -o /tmp/HighSierra.iso Ready to get started? Let’s jump in! Step One: Create a macOS High Sierra ISO File If you’re on a Mac and want a macOS virtual machine for use on that Mac, we recommend checking out out Parallels Desktop Lite instead, because it can create macOS virtual machines for free and is a lot easier to work with. Borrow a friend’s Mac for an hour if you don’t have one, and you should be fine-everything beyond step one of this tutorial can be done on your Windows PC. You could, we suppose, obtain a High Sierra ISO by other means, but we don’t recommend it.

NOTE: In order to get this working, you will need access to a real Mac in order to download High Sierra.

RELATED: Beginner Geek: How to Create and Use Virtual Machines To make things a little easier for people, we’ve combined methods from a few different forum threads into a single, step-by-step tutorial, complete with screenshots. Other than that, though, this is macOS High Sierra, running smoothly in VirtualBox. The only thing not working is sound, which for some reason is highly distorted or nonexistent. Some of the folks at the InsanelyMac forums have figured out a process that works. We haven’t yet tested it ourselves, but we’ve heard good things. It promises to take you through the process of installing and setting up a macOS virtual machine. If you want to install a newer version of macOS in VirtualBox, check out this script on GitHub.
The now-abandoned systems will be supported with security-only updates to the last-chance Catalina through the summer of 2022, however.Update: The instructions here apply to older versions of macOS. Macs that didn't make Big Sur's list but were on Catalina's included the mid- and late-year 2012 MacBook Pro, mid-2012 MacBook Air, mid-2012 and late-2013 iMac, and late-2012 Mac Mini machines. So it wasn't a surprise when the system requirements were narrowed for the new OS.Īccording to Apple, these Macs will run Big Sur:

Apple has used an odd-even cadence for its operating system upgrades' requirements, alternately retaining the prior year's models on the newest version's support list in odd-numbered years with odd-numbered editions, as in 2019's Catalina, macOS 10.15, and dropping models from the list during even-numbered years with even-numbered editions.īig Sur would have been 10.16 if Apple had hewed to tradition, but it's still an even-numbered upgrade because of its year.
