Run these commands one at a time ( Update :: I changed the 5130m to 5200m based on feedback from the comments)īut I am trying to use the ISO file I created to launch a virtual machine (10.13 Host, 10.14 guest).

Overview of how to create a bootable macOS 10.13 High Sierra ISO image:Ĭlick this link to open the macOS High Sierra download in the App StoreĮspecially if you’ve already upgraded to high sierra and deleted the installer data (with CleanMyMac etc) you will need to download this again before proceeding with this article. This means you actually need a Mac or a MacBook to create this bootable ISO.
To abide with Apple’s terms of use, you must go through official channels to obtain the macOS installer. This guide will also be useful for those who can run Virtual Machines of macOS in environments like VirtualBox etc. As an owner of a MacBook Pro, it’s slightly unsettling that I wouldn’t necessarily be able to plug in a bootable USB or insert a DVD with the macOS installer image in the event that I needed to re-install my OS because my SSD ate the dust, or something. OS X was a different story, but also you had to pay for those versions. See OSX guests on non-Apple hardware scottgus1 Site Moderator Posts: 15199 Joined: 30.Normally you can’t obtain bootable media of macOS. (*) You need to have Mac hardware to legally run a Mac guest. How to do this with a Mac image would be a subject for a Google search.
If your image was a Macrium image I would suggest using a Macrium boot CD on the guest with the mounted VHD and restore the image to the guest.
Try to figure out how to do something similar on you Mac. On a Windows PC one could make a VHD virtual disk, mount it on the PC, load the image into the VHD, then unmount it and attach the VHD to the guest as a second drive. dev/disk0 (internal, physical): : TYPE NAME SIZE IDENTIFIER 0: GUIDpartitionscheme 251.0 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: AppleAPFS Container disk1 150.4 GB disk0s2 3: AppleHFS Recovery HD.

Getting the image into the virtual environment can be tricky. The problem is I am unsure on how to increase the size of my main Mac OS partition as I have no experience with this new container disk stuff.

The Virtualbox manual section 1 shows how to start a guest and install an OS from a CD or ISO. How would you install an image on a real Mac? Do the same to a Virtualbox guest running on a Mac (*). Fig. I'm no Mac guru, but Virtualbox essentially provides 'hardware' you can do anything with that you can do with a real computer. Open the Terminal application and type the following command to list disks: diskutil list.
