If you made a Time Machine backup of your Mac, Migration Assistant can use that backup to restore your personal files, including apps and everything in your user account.

If you prefer to restore just a few files or earlier versions of those files, learn how to use Time Machine to restore specific files.

Uses of Disk Images Software Distribution. A disk image is often used to download software on the Internet. Mac users have probably downloaded many DMG files that are mounted as virtual drives on your desktop. When used in this manner they are a reminder of a time when floppy disks ruled the software distribution world. 5) Don't forget to unmount the.dmg disk image if you mounted one. Here we execute the 'mount' command to determine which virtual. Disk device our dmg is mounted as (in this case it is /dev/disk2s2). Then we use 'hdiutil detach' to unmount it.

The SERVICEcamera transmits live images from the machine directly into the chat and relevant parts of the image can be marked. In this way, it is possible to determine which spare parts are required.' Mario Bettineschi, Managing Director Seriomould. 11 Machine tools from DMG MORI; DMU 50 with NETservice & SERVICEcamera.

  1. If you need to reinstall macOS, do that before continuing. For example, if your Mac starts up to a flashing question mark, you need to first reinstall macOS.
  2. Make sure that your Time Machine backup disk is connected to your Mac and turned on.
  3. Open Migration Assistant on your Mac. It's in the Utilities folder of your Applications folder.
    If your Mac starts up to a setup assistant, which asks for details like your country and network, continue to the next step, because the setup assistant includes a migration assistant.
  4. When 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.
  5. Select your Time Machine backup, then click Continue.
  6. Choose a backup and click Continue.
  7. Select the information to transfer.
    In this example, John Appleseed is a macOS user account. If it has the same name as an account already on your Mac, you're prompted to either rename the old account or replace the one on your Mac. If you rename, the old account will appear as a separate user on your Mac, with a separate home folder and login. If you replace, the old account will delete and then replace the account on your Mac, including everything in its home folder.
  8. Click Continue to start the transfer. Large transfers might need several hours to complete.

I ran into an interesting macOS error while working with a customer. I didn't find a lot of good search results addressing the issue, so I decided to write up a post about it myself.

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:

  1. In most cases, the downloaded dmg file is actually corrupt or had an error downloading. If possible, try downloading the dmg again, turning off any download assistant plug-ins you may have. You can try downloading the file in a different browser as well. Or if you don't need to be logged in to the site to download the file and you want to be fancy, you can try curl -O url in Terminal to download the file. (There's an example of that in my screenshot below.)

  2. Reboot your Mac if you haven't already tried that. Apparently there is an issue sometimes after opening too many dmg files, that is fixed with a reboot.

  3. Try mounting the DMG on the command line in Terminal. We will at least get some sort of useful error message to go on if it still fails:

    • Open Terminal: In Spotlight, the search magnifying glass at the upper right corner of your screen, search for Terminal, and press enter to open the Terminal app.

    • Type hdiutil attach -verbose into the terminal. Add a space at the end, but don't press enter yet.

    • Drag the dmg file from your Finder window onto the Terminal window and let go. This will fill in the location of the dmg file into your Terminal window.

    • Press enter.

  4. 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.

    Here's an example of the end of hdiutil attach -verbose output that shows an APFS error due to an older version of macOS:

  5. Think about if you have any kind of security policies on this machine to prevent writing to external drives (thumb drives, optical drives, etc). I haven't seen this one in action, but I read about this being a possibility while researching the issue.

  6. 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.

  7. A new discovery from a reader (thank you, Colby!) is that APFS DMGs won't mount if you're booted in macOS booted in Safe Mode. (Who knew!?!) If you're not sure if you're in safe mode, select the Apple menu  > About This Mac > System Report button, then select the 'Software' heading from the left column. To exit safe mode, restart your Mac, without holding Shift during startup. Or, if you previously set your Mac to always boot into safe mode using nvram, turn off safe mode and have your Mac boot normally on the terminal:

    • Open Terminal: In Spotlight, the search magnifying glass at the upper right corner of your screen, search for Terminal, and press enter to open the Terminal app.

    • Type/paste sudo nvram boot-args=' and press enter.

    • Restart your Mac.

  8. Another new discovery (thank you, Iris!) is that if you have APFS by Paragon software installed on a Mac that can read APFS itself, it can interfere with opening the DMG. So if you used APFS by Paragon and then updated your Mac, you may need to uninstall it.

One footnote for people having issues opening ISO files. Another new discovery is that 'hybrid' ISO files (think Linux installers) don't open correctly automatically and need to be manually attached and mounted (this is NOT advice for normal .dmg files.)
