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. #I need a mac os x boot disk for vbox without a mac how to#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. #I need a mac os x boot disk for vbox without a mac install#If you want to install a newer version of macOS in VirtualBox, check out this script on GitHub. Apple also offers Shift-Command-Option-R, which installs the version of OS X or macOS with which your computer shipped, or the next oldest compatible system still available for download.Update: The instructions here apply to older versions of macOS. ![]() While Command-R at startup always installs whatever the most recent version you installed on your Mac, holding down Command-Option-R brings down the very latest compatible version that can be installed. However, if you have normal Recovery installed and it refuses to install macOS for some reason, you can manually invoke Internet Recovery. #I need a mac os x boot disk for vbox without a mac full#There, the Mac reaches out over a Wi-Fi or ethernet connection to download the relatively modest Recovery software, which then bootstraps the download of the full macOS installer.Īpple says Internet-based Recovery should happen automatically on supported models, and you should see a spinning globe when that mode is invoked while the download occurs. #I need a mac os x boot disk for vbox without a mac upgrade#However, there’s yet another option: macOS Recovery over the Internet, which requires either a Mac model released in 2012 or later, or most 20 models with a firmware upgrade applied. When complete, it installs it and reboots, and places the installer in the Applications folder. (Apple doesn’t document that, and I haven’t had to test that for years.)įailing finding it, Recovery downloads the currently installed version of macOS (or OS X), which is about 5GB. In that mode, when you choose to reinstall without erasing the drive, my recollection is that Recovery looks for the current OS system installer on your startup disk in the Applications folder, and uses that. That allows you to run Disk Utility, reinstall or wipe and install the system, access Terminal for command-line functions, and so on. Normally, you can start up a Mac while holding down Command-R to boot into what Apple now calls macOS Recovery. The article includes instructions on obtaining the installer, which might involve you having to use someone’s else Mac to download it, if you don’t have a replacement Mac on hand yet.īut if you can’t get access to another Mac or the necessary drive, it’s still possible to use a different Recovery mode on all recent Macs, dating back to 2010. We have instructions for making a bootable installer with macOS Sierra (as well as archived versions for several previous releases). Recovery lets you install onto an erased partition, but only if Recovery wasn’t erased, too!īecause Recovery didn’t work, the fastest way to install fresh is to make or borrow a macOS installer on a USB flash drive or a disk drive. There are a couple of options with an erased partition. My friend was wiping my Mac so I could sell it and I’m pretty sure they’ve deleted the start up disk? It’s not letting me reinstall the OS on a recovery startup. ![]()
