Instructions for installing, setting up and virtualising a physical Mac/hard disk/disk image file

On Mac menu bar find Parallels logo choose Actions Take snapshot. In the appeared window specify the name of the snapshot and click OK. Revert to a Snapshot In Parallels Desktop 15. Start Parallels Desktop and the virtual machine in which you want to revert to the snapshot. On Mac menu bar find Parallels logo choose Actions Revert to Snapshot. To remove a virtual machine please follow these steps:Launch Parallels Desktop.app, but do not start your virtual machine.Click on the Parallels icon on the Mac menu bar select Control Center.Right-click on your virtual machine and select Remove.

Virtualising a physical Mac/hard disk/clone/disk image file

The ability to virtualise an existing Mac/macOS installation is important and very useful as it is an easy way to continue running your old Mac and also a possible way to run 32-bit applications that do not run on macOS 10.15 or later. MacStrategy presents this special guide to virtualising a physical Mac/hard disk/clone/disk image file.
This article deals with transferring an existing Mac running Mac OS X / OS X / macOS to a virtual machine, or take a bootable storage device/clone/disk image and convert it into a virtual machine. If you would prefer to set up/install a virtual machine with a clean Mac OS X/OS X/macOS from scratch please see one of the following articles instead:

• Mac OS X 10.6 Snow Leopard (Server) - costs money but you may already be running/want to run this to be able to use PowerPC/Rosetta based applications
• OS X 10.7 - OS X 10.8 is better
• OS X 10.8 - costs money but if you already own it/want to pay for it, it runs very efficiently in a virtual machine and there are few internet/iCloud based services clogging it up
• OS X 10.9 - was very kludgy and slow when installed on a hard disk
• OS X 10.10 - was slow when installed on a hard disk, does not support latest Apple internet/iCloud based services
• OS X 10.11 - free, supports most internet/iCloud based services
• macOS 10.12 - free, supports most internet/iCloud based services
• macOS 10.13 - buggy, slow, new Apple File System
• macOS 10.14 - still being revised, new Apple File System

Virtualisation Software

• Parallels Desktop [£79.99 inc VAT - 14 day free trial available]
  
• VMWare Fusion [£70.00 inc VAT - 30 day free trial available]
• Oracle VirtualBox [FREE - Open source under GNU General Public License (GPL) version 2]

Instructions

NOTE: This document was written using a Mac mini (2014 model) with macOS 10.14 Mojave running in 64-bit only test mode and using Parallels Desktop 14.1.2, VMWare Fusion 11.0.2 and VirtualBox 6.0.4.

Preparation

NOTE: You will need the following:

1. Mac computer for hosting your preferred guest OS preferably with a working Recovery Partition
2. Make sure your actual, physical Mac has a working internet connection e.g. use a web browser to go to https://www.apple.com and see if you can view a web page
3. Purchase/install/update your preferred virtualisation software (see list above)
4. On later versions of macOS your preferred virtualisation software will require specifically allowing their System Extension(s) to run via System Preferences > Security & Privacy, plus they may require to be granted access to Accessibility
5. Purchase/download/obtain your preferred cloning software (we list some in our How To Clone Your Primary/Boot Drive article - we highly recommend Carbon Copy Cloner)
6. If you going to clone from a physical Mac or a clone on a bootable storage device, if possible, boot that system first to make sure it works/is bootable, and also de-activate any software e.g. Adobe Creative Suite (applications)
7. Bootable physical Mac/hard disk/clone/disk image file of your old system
NOTE: If you have the original Mac you will need to clone its startup disk either to an external storage device (preferably USB) or to a disk image first using, for example, Carbon Copy Cloner.
8. Make sure you have plenty of free space on your physical Mac's hosting drive - you will need to create a basic Mac OS X / OS X / macOS virtual machine where you may need to copy the disk image file of your old system to + an additional virtual machine drive that has enough space to host your old system
9. If you are using an external storage device for your bootable clone or to hold the disk image file it's best to rename it to something that is easy to recognise e.g. 'VM Transfer'
10. Create a basic/clean Mac OS X / OS X / macOS virtual machine - if your Mac host computer has a working Recovery Partition, in VMWare Fusion you can easily do this by going to File menu > New… > select 'Install macOS from the recovery partition' > click 'Continue' and follow the on-screen instructions. Alternatively, use our step-by-step guides:

Instructions for virtualising a physical Mac/hard disk/clone/disk image file with:

Parallels Desktop Instructions

We have not tested this in Parallels Desktop but you should be able to do something similar to what we did in VMWare Fusion - we will update this article when we have more time to test this. Don't forget to donate to us (use the button in the bottom left corner of this web page).

VMWare Fusion

1. Make sure the basic/clean Mac virtual machine you created in the preparation section above is shutdown
2. Go to Virtual Machine menu > Settings > Hard Disk (SATA) > click 'Add Device…' > select 'New Hard Disk' > click 'Add…' > choose size > Apply
NOTE: This additional virtual machine drive must be larger than the space used by the physical Mac/hard disk/clone/disk image file of your old system.
3. Start up/boot the virtual machine
4. At the Desktop Mac OS X / OS X / macOS will recognise the additional virtual machine drive and ask you to initalize it > click 'Initialize' (which will open Disk Utility)
5. Select the unformatted additional virtual machine drive on the left (VMware Virtual SATA) - this is the one without 'Macintosh HD' underneath it
6. Set 'Name:' to 'Second HD', 'Format:' to 'OS X Extended (Journaled)', and 'Scheme:' to 'GUID Partition Map' > click 'Erase' to initalize/format the additional virtual machine drive (it should now mount/appear on your Desktop if you have the virtual machine's Finder 'Preferences' set to show 'Hard Disks')
7. Click 'Erase'
8. If OS X / macOS asks you whether you want to use the additional virtual machine drive for Time Machine Backups click 'Don't Use'
9. Quit Disk Utility
10. Connect your physical Mac/clone or hard disk with the disk image file of your old system to your virtual machine OR, if you have enough space, copy the disk image file of your old system on to the virtual machine's Desktop
11. The physical Mac/clone or hard disk with the disk image file of your old system on it should now mount/appear on your Desktop (if you have the virtual machine's Finder 'Preferences' set to show 'Hard Disks') OR double click to open the disk image file of your old system that is now on your virtual machine's Desktop
12. Using your cloning software of choice, clone your physical Mac/hard disk/clone/disk image file of your old system to the additional virtual machine drive e.g. with Carbon Copy Cloner:
13. In the virtual machine go to Apple menu > System Preferences > Startup Disk > set it to 'Second HD'
14. Quit System Preferences
15. Shutdown the virtual machine (Apple menu > Shut Down) - not Restart
16. Go to Virtual Machine menu > Settings > Hard Disk (SATA) > make sure 'File name:' is 'Virtual Disk.vmdk' > click 'Advanced options' at the bottom > click 'Remove Hard Disk'
17. You will be given the choice to keep or Trash the virtual disk file which is your choice (it might be worth keeping the original virtual disk if you have plenty of space as it is a clean Mac OS X / OS X / macOS virtual machine)
18. Go to Virtual Machine menu > Settings > General
19. Change the virtual machine's 'Name' to something that is relevant to your original Mac system e.g. 'Old OS X 10.8 Mac Pro'
20. Change the virtual machine's 'OS' to match that was on your physical Mac/hard disk/clone/disk image file
21. Go through and configure your required virtual machine custom settings:
22. Start up/boot the virtual machine
23. To avoid confusion with your host Mac, rename the virtual machine's hard disk from 'Second HD' to something that is different to your current hard disk e.g. 'Virtual OS X 10.8 HD'
24. Go to Virtual Machine menu > Install VMWare Tools
25. Install VMWare Tools, following the on screen instructions and restart the virtual machine when complete (you may get a message about the installer certificate being out of date and this appears to stop the Tools installing so things like drag and drop are not supported [with this guest OS])
26. If you are running an unsupported version of Mac OS X / OS X / macOS make sure you check out our Securing Older Operating Systems article

Q. What are the current, supported versions of macOS?

A. macOS 10.15 (Catalina), 10.14 (Mojave) and macOS 10.13 (High Sierra) are supported by Apple. The latest security updates are:
• macOS 10.15 - included in the macOS 10.15.4 Update

If you used Time Machine to create a backup of your Mac, you can restore your files from that backup or a local snapshot on your startup disk. You might want restore your files after the originals were deleted from your Mac, or the hard disk (or SSD) in your Mac was erased or replaced, such as during a repair.

Restore from a Time Machine backup

When you restore from a Time Machine backup, you can choose to restore all your files, or restore both the Mac operating system (macOS) and all your files.

You should receive a message that says SHSH SUCCESSFULLY SAVED if everything worked correctly. Ios 6.1 3 shsh blobs download. Click on Save SHSH, and Tiny Umbrella will attempt to save the SHSH blobs for iOS 6.1 (or the latest iOS firmware that Apple is signing), and save it to the directory you selected in Step 6. Step 9: Open up the SHSH folder that you created on your desktop in Step 6, and verify that the SHSH blob for your device is there. Request SHSH From CydiaStep 6: Change the save SHSH directory to an SHSH folder on your desktop, that way you can easily find, verify, and backup your SHSH blobs in a more familiar directory.Step 7: Click the Log tab so that you can prepare to view the status of your save attempt.Step 8: Now it’s time to actually save the blobs.

Restore all your files

1. Make sure that your Time Machine backup disk is connected to your Mac and turned on. Then turn on your Mac.
   
2. Open Migration Assistant, which in the Utilities folder of your Applications folder.
   • If your Mac starts up to a setup assistant, which asks for details like your country, keyboard, and network, just continue to the next step. The setup assistant includes a migration assistant.
   • If your Mac doesn't start up all the way, or you also want to restore the macOS you were using when you created the backup, follow the steps to restore both macOS and your files.
3. When you're asked how you want to transfer your information, select the option to transfer from a Mac, Time Machine backup, or startup disk. Then click Continue.
   
4. Select your Time Machine backup, then click Continue.
   
5. If you're asked to choose from a list of backups organized by date and time, choose a backup and click Continue.
   
6. Select the information to transfer, then click Continue to start the transfer. This screen might look different on your Mac:
   
7. If you have a lot of content, the transfer might take several hours to finish. When the transfer is complete, restart your Mac and log in to the migrated account to see its files.
   

Restore both macOS and your files

These steps erase your hard disk, then use your backup to restore both your files and the specific version of macOS you were using when you created the backup.

1. Make sure that your Time Machine backup disk is connected and turned on.
   If your backup disk isn't available, keep going: You might be able to restore from a local snapshot on your startup disk.
2. Turn on your Mac, then immediately press and hold Command (⌘)-R to start up from macOS Recovery. Release the keys when you see the Apple logo or spinning globe.
3. When you see the macOS Utilities window, choose the option to restore from a Time Machine Backup.
   
4. Click Continue until you're asked to select a restore source, then select your Time Machine backup disk. Or select your startup disk (Macintosh HD), which might have a local snapshot you can restore from.
   
5. Click Continue. If your disk is encrypted, you're asked to unlock the disk: Enter the administrator password you used when setting up Time Machine, then click Continue again.
6. Select a backup, if available, then click Continue.
   
7. Select a destination disk, which will receive the contents of your backup. If restoring from a local snapshot, you aren't asked to select a destination.
   
8. Click Restore or Continue. If your Mac has FileVault turned on, you're asked to enter your administrator password to unlock the disk.
9. When done, restart your Mac.
