Mac Os Sierra Disk Image Download: Why You Should Try This Amazing OS

You can create a disk image that includes the data and free space on a physical disk or connected device, such as a USB device. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 80 GB in size and include data and free space. You can then restore that disk image to another volume.

The error was as the screenshot above shows; trying to open a dmg (disk image), macOS showed the error "no mountable file systems". If you see the "no mountable file systems error" while opening a dmg, here's what you should try:

macOS Sierra (10.12) and earlier is not able to mount the new Apple File System (APFS). So if you're on macOS Sierra (10.12) or earlier and you ran hdiutil and see references to Apple_APFS or error 112, the issue is likely legitimate incompatibility, and this disk image won't open on this Mac without an update to the operating system.

Another suggestion added by a reader (thank you, Markus!) is that filesystem errors on your main Mac drive could be the cause of the disk image mounting errors. Here are instructions from Apple for scanning and repairing errors using Disk Utility. Note that in order to scan and repair errors on your main Macintosh HD drive, you'll need to reboot your Mac into recovery mode. You'll want to choose Disk Utility in the utilities listed in the recovery mode menu.

Hi! I had problems with my iMac and tried to erase the OS and re-install, but I did something wrong and now all I have is asingle partition with OS X Base System that is the size of my HD (1 TB), see picture 1. This new disk image cannot be partitioned: when I hit the + sign in the partition screen, nothing happens. In the Disk Utility, the options for erase, restore and unmount are all unavailable (see picture 2), I imagine that's because you normally cannot do any of these on the OS X Base System disk. This disk is also locked, so I cannot re-install High Sierra (see picture 3).

I suspect you are looking at the installer disk image that is part of the installation system. Have you tried restarting the computer to see if the installer will pick up and continue? If the installer does not continue then get yourself back into the Recovery HD. Click on the Install OS X option in the Utility Menu and click on the Continue button. You may be asked for your Apple ID and/or Admin password so have them handy.

(UPDATED OCT 2022) How to install macOS (High Sierra 10.13, Mojave 10.14, Catalina 10.15, Big Sur 11) on Windows 10 in a VMware Workstation virtual machine including Google drive links to download the VMware VMDK virtual disk images.

This example is for installing High Sierra 10.13 on Windows 10 using VMware Workstation 15. This guide will also work for other versions of macOS e.g. Mojave 10.14, Catalina 10.15 or Big Sur 11. Google drive links to download the virtual disk images for these macOS versions are also included below.

1 Run VMWare macOS Unlocker2 Download macOS VMware VMDK disk image file from Google Drive3 Create macOS VMware Workstation Virtual Machine4 Edit the Virtual Machine settings5 Attach the recovery VMDK disk image6 Boot virtual machine from the recovery disk7 Run Disk utility to erase the OS disk8 Install macOS on the virtual machine9 Install VMware tools

The VMware VMDK images below are based on macOS recovery installation images, they are not the full macOS operating system installation image. The recovery installer will boot macOS and download the full operating system during setup.

We need to attach the macOS recovery disk image (that you downloaded in step 2) so we can boot the VM and run the macOS installer. The VM will have two hard disks attached - the recovery disk macOS-recovery.vmdk and another 100GB hard drive that we will install macOS onto

For distribution outside of the Mac App Store, the preferred options are to use a signed disk image (DMG) or signed installer package. Signing these allows validation of the contents and their source. ZIP archives may also be used, but this is discouraged.

If using a disk image to ship an app, users should drag the app from the image to its desired installation location (usually /Applications) before launching it. This also applies to apps installed via ZIP or other archive formats or apps downloaded to the Downloads directory: ask the user to drag the app to /Applications and launch it from there.

This practice avoids an attack where a validly signed app launched from a disk image, ZIP archive, or ISO (CD/DVD) image can load malicious code or content from untrusted locations on the same image or archive. Starting with macOS Sierra, running a newly-downloaded app from a disk image, archive, or the Downloads directory will cause Gatekeeper to isolate that app at a unspecified read-only location in the filesystem. This will prevent the app from accessing code or content using relative paths.

Important: Starting with macOS Sierra, only XIP archives signed by Apple will be expanded. Developers who have been using XIP archives will need to move to using signed installer packages or disk images.

Note: A disk image signed on OS X 10.11.5 or 10.11.6 may not be able to be re-signed. In this situation, the operation will appear to succeed, but the signature will be invalid. If you encounter this condition, sign a new (unsigned) copy of the image on macOS Sierra or later.

In this example, hdiutil is used to create the ISO image. Hdiutil is a built-in console utility that is available on macOS; it is used to work with disk images as data containers that emulate disks. The DiskImages framework is used by hdiutil to manipulate the disk images.

Now that your bootable ISO image with the macOS installer is ready, you should prepare your ESXi host for the installation of macOS as a guest OS on VMs. You need to enable SSH access, download the patch, copy the patch to the file system of the ESXi server, and patch the ESXi server.

After downloading the patch, copy the patch files to the datastore on ESXi. You can use WinSCP, which supports the transfer of files over SSH by using SFTP, SCP, WebDAV, or S3 protocols (in Linux you can use the equivalent software). WinSCP has a user-friendly graphical user interface (GUI), and consists of two main panels. Copy the unlocker files from your local directory to your datastore on the ESXi server. In this example the unlocker patch and the macOS Sierra installation ISO image (Sierra.iso) were created beforehand, and are placed in C:\Virtual\images_MacOS for convenience. The patch is copied to /vmfs/volumes/datastore1 on the ESXi server. Sierra.iso would be copied to the datastore40. Later, you can mount the ISO image from the datastore to the virtual DVD drive of the virtual machine.

This section explains how to correctly create a macOS Mojave bootable ISO image. First, download the macOS Mojave installer from the App Store. In the current example, a machine running macOS Mojave is used for downloading the macOS Mojave installer to avoid using third party downloading tools. Open AppStore, find macOS Mojave, click View and then click Get to download the installer. Notice that you need a full installer whose size is about 6.03 GB. If after downloading the installer, installation starts automatically, cancel it. After successfully downloading you can see the Install macOS Mojave.app file in the Applications directory. Open Finder and click Applications in the left pane of the Finder window to check the installer file.

Use the set of commands explained below in order to create an installation ISO image for further installation of macOS Mojave on VMware ESXi or VMware Workstation. Make sure you have enough free space on your disk.

Now you have a bootable ISO installation disk image of Mac OS X 10.14 Mojave and you can install macOS Mojave on your VMware ESXi host. The rest of actions are similar to actions explained above for installing macOS Sierra on a VM of the VMware ESXi format but you should be aware of the following features:

Does your 2010 MacBook have a working OS at present? If so, you may be able to download the Sierra disk image on that computer, open it, and run the installer package, which will create the Sierra installer application. You can then use that to create a USB installer (or simply run the installer application).

You can't use the Sierra disk image directly to create a VM. It is not a bootable disk image. The disk image contains an installer package. Using that package creates "Install macOS Sierra.app" in your Applications folder. You need that application to create a USB installer, or to create a Sierra virtual machine.

The installer model check is bypassed if it is running inside a VM, so you should be able to use a macOS VM to open the disk image, run the installer package, and create "Install macOS Sierra.app". Your existing Catalina VM should be able to do this.

If Catalina is too new to run the Sierra disk image's installer package, then you could set up an older macOS version as a VM. High Sierra (10.13) and Mojave (10.14) can be downloaded as installer applications (rather than disk images). If your Mac model is old enough, you should be able to get them from Apple's support site. If your Mac is too new, then you should be able to get them from inside your Catalina VM. Once you have the "Install macOS High Sierra" (or Mojave) application, copy it to the host (if necessary), use it to create another VM, then try the Sierra disk image inside that VM. 2ff7e9595c
