Sep 26, 2018 Much like prior versions of Mac OS, you can easily create a bootable install drive for MacOS Mojave 10.14. These boot install drives allow for things like easily formatting a Mac to perform a clean install of macOS Mojave, installing macOS Mojave onto multiple Macs without them each having to download the installer, or even as a troubleshooting tool since it can be booted from by any. Jul 10, 2018 In this tutorial we will show you step by step how to create ans make a bootable USB Flash Drive from a Mac OSX.DMG image file from Windows 10 (Sometimes called pen drive / thumb dive) so you. The Mac that the PowerBook G4 is connected to is very slow, but is presently creating a.dmg image of it's harddrive and I was just wondering if this would prove to be worth it, as it appears to be take a day or two to create the image uncompressed. Mar 15, 2018 It can also mount Mac.dmg disk images to get at the files inside them. This application’s read-only nature isn’t necessarily a bad thing. It ensures that no bug in the third-party driver can damage your Mac-formatted drive and the files on it. If you want to copy a hard drive from one to another, just choose mode “Copy Disk”. Step 2: Choose the source drive and destination drive. DoYourClone for Mac will create a disk image of the source hard drive and save the disk image to the destination hard drive, here are some tips. Dec 28, 2019 How to Make a DMG File on a Mac. One way to store or group files on a Mac is to create a Disk Image. A Disk Image is a file which has the properties of a separate hard drive or CD and allows for greater password.

My recent experience with water damage to my new 16-inch MacBook Pro reinforced two practices that I’ve followed for many years; making a bootable backup and creating a bootable macOS install drive. While I was able to reload my MacBook from the bootable backup drive, I know that it’s always good practice to have one drive — a cheap flash or hard drive — that can be booted for one purpose, that of doing a clean install of macOS. Diskmaker X has been my tool of choice for making bootable install drives for years, and in this article, I’ll show how to create one for macOS Catalina.

You can always use the Mac Terminal app to create a bootable installation disk, but DiskMaker X automates the process. The app is free, but a donation is suggested. With a blank external hard disk or flash drive at your fingertips, follow these instructions.

Download DiskMaker X 9

Click the DiskMaker X link in the first paragraph of this article and download a copy of DiskMaker X 9 to your Mac. Note that the developers of the app also have DiskMaker X versions available back to Mac OS X 10.7 “Lion”, which is helpful if you wish to load older Macs with their original operating system versions. You can also create a single drive with installers for every Mac operating system back to Lion!

Install DiskMaker X 9

To install DiskMaker X 9, locate the installer disk image (.dmg) file. By default, it should be in the Downloads folder. Once you’ve located the installer, double click it to mount the disk image. A window similar to the one seen below appears:

Install DiskMaker X 9 on your Mac by dragging the app icon to the Applications folder alias as shown by the gray arrow on the installer window. Before you launch DiskMaker X 9, you need to download the macOS Catalina installer.

Download the macOS Catalina Installer

Have you already upgraded your Mac to Catalina? If you have, the installer probably isn’t in your Applicaitons folder. No problem! It’s available on the Mac App Store.

If you have already installed Catalina, clicking the “Get” button in the Mac App Store will launch System Preferences > Software Update, and the following dialog appears:

Whether you’re running an earlier version of macOS or the latest, click the Download button to place the Catalina installer into the Applications folder of your Mac.

Have Your Drive Available

Earlier I mentioned that you need a drive of some sort. A USB Flash Drive is usable, although slow, as long as it has at least 8GB of capacity. OWC’s 16.0GB Performance Flash Drive is perfect for creating a bootable installation drive, and it’s very inexpensive.

For speedier installations, an inexpensive USB 3.0 drive like the 1TB OWC Express USB 3.0 is perfect, or if you want the fastest possible installation for a group of Macs, the 240GB SSD OWC Envoy Pro EX with Thunderbolt 3 is an inexpensive option.

DiskMaker X erases everything on the drive when you create the bootable macOS Catalina installation drive, so if you’re planning to use the same drive for other utilities or troubleshooting tools, or perhaps use it as a backup drive, do that after you’ve created the bootable installation drive.

Give DiskMaker X Authorization

macOS 10.15 Catalina uses a Privacy Control mechanism that causes multiple alerts to appear on your screen during the creation of the boot drive, so it’s necessary to give Accessibility authorization to “control your computer”. To do so:

Launch System Preferences from the Dock, the Applications folder, or from Apple () menu > System Preferences
Click Security and Privacy
Click the Privacy tab
Click Accessibility
Unlock the preference by clicking the lock icon in the lower-left corner of the System Preferences window, then enter your password or use Touch ID to continue
Drag the DiskMaker X 9 icon from the Finder to the right part of the window, or click the + button and select the DiskMaker X app in the Applications folder. DiskMaker X is added to the list of apps that can control your Mac (see screenshot below).

Be sure to remove this authorization once you’re done using DiskMaker X to create your bootable drive.

Note that there are other alerts that still appear when using DiskMaker X even though you have authorized this setting. Click OK when the alerts appear. Mac 0s x 10.6 snow leopard dmg.

Launch DiskMaker X 9

Now we’re ready to make our bootable disk. Attach the drive to the Mac, make sure that the drive is visible from the Finder (in some cases a drive icon may appear on the Desktop), then launch DiskMaker X 9. If you’ve kept older macOS installers in your Applications folder, DiskMaker X asks which version of the operating system you want to use to make a boot disk. Select the version — in this case, macOS Catalina (10.15) — and then the following dialog appears:

To continue with the copy of the macOS installer that was found in /Applications, click “Use this copy”. If the installer is elsewhere, click “Use another copy…” to locate the installer file. Continuing, DiskMaker X 9 asks for the type of disk you’re using. In this example, I am using an OWC Mercury Elite Pro mini drive, so I click “Another kind of disk (erase only partition).”

NB BootDiskUtility by default already has FakeSMC.kext installed here. DSDT.aml with or without SSDT.aml-EFI/CLOVER/ACPI/patched (don't need one if your DSDT is auto patched by Clover in config.plist). Kexts eg FakeSMC, -EFI/CLOVER/kexts/ or /Other. Download high sierra dmg without app store on a android. You may need to add for your laptop keyboard/trackpad to work. If UEFI booting, you will most likely need one of the OsxAptioFixDrv-64 drivers copied from /EFI/CLOVER/drivers-off/drivers64UEFI to /EFI/CLOVER/drivers64UEFI.If you want to use the installer to run High Sierra in Windows on VMware, you can follow my to set up the Virtual Machine and replace Clover's default config with (which is compatible to run in VMware).

Whatever drive you use will be completely erased. If you want to create a single disk that can install Yosemite, El Capitan, Sierra, High Sierra, Mojave, and Catalina, use Disk Utility (in the Applications/Utilities folder) to partition the drive into six separate volumes, one for each OS version.

For this example, my drive is named “OWC Mercury Elite Pro mini”, so I click on it to select it, then click “Choose this disk”.

Of course, DiskMaker X doesn’t want you to accidentally erase the wrong disk, so it asks if you really want to “Erase then create the disk”. If everything is the way you wanted, click the highlighted button (see image below).

We are go for launch! Now you will see a few more dialogs, one asking if you are in a light mood or wish to “come to the dark side” — that has to do with the type of disk icon that will be assigned to your boot disk, so make your choice.

Be aware that DiskMaker X 9 requests your administrator login and password, so be prepared to type (see screenshot above). You are also asked to give permission to DiskMaker X 9 to “access files on a removable volume” (your bootable install disk), so click OK when prompted as seen below.

During the disk creation process, temporary windows open and close, files are copied, and you may be asked if you wish to use your disk as a Time Machine backup drive — if this happens (and it may occur more than once) click “Don’t use”. You can do that later if you want to use the same bootable install disk as a Time Machine backup drive. If you’re running a virus protection app, it may ask if you wish to scan the disk; be sure to tell it to leave your disk alone!

You’ll know that DiskMaker X 9 is done when you hear a lion roar, and a dialog is displayed to inform you of the completion. At that point, you can reboot your Mac while holding down the Option (Alt) key to select a boot drive, or use System Preferences > Startup Disk to set the drive you just created as the boot drive.

If you like DiskMaker X 9, consider making a donation by clicking on the appropriate button.

Many thanks to Guillaume Gète and the rest of the DiskMaker X team.

A clone of your Mac is essentially a backup of all the data you can make bootable, so when you connect the disk to another Mac, you just reboot and carry on from where you left off.

Cloning your Mac’s main drive is a great way to protect yourself against potential problems when, for example, you might be installing a new version of macOS — especially if it’s still in beta. But clones can also be of use during travel or business trips, if you’re worried that your Mac might get lost, stolen or damaged.

If you need to recover files from a failing system, you can clone the whole drive and then recover files from the clone, removing the possibility that the drive will fail completely before your files are recovered.

A clone backup differs from the now popular incremental backup in that it creates a snapshot of your Mac that is preserved for as long as you want it, whereas incremental backups update themselves at regular intervals.

How to create a clone of your Mac

There are a few things you need in order to clone your Mac and use it as a backup. First, you need an external hard drive or SSD with a volume that’s clean and empty, which means it should either be brand new or completely erased beforehand.

Next, you’ll need software to create the clone. There are several applications that are available for Macs that you can use. We recommend going with Disk Drill. Disk Drill can help you recover data from a failed drive and allows you to create byte-for-byte copies of a disk and save them as a disk image. In other words — clone your Mac.

Finally, you need a safe place to store your clone — a backup is no good if you can’t find it when you need it.

Before you start

If you have a regular backup routine, it’s a good idea to run one before you start the process of cloning your Mac. It sounds daft to run a backup just before you create a backup, but it’s always better to be safe than sorry.

If you’re using a disk that’s been used before, you’ll need to erase it completely to make it ready for the clone. We’ll assume you’re going to use the whole disk as a single volume.

Erase the drive and create a disk image

Plug the external hard drive into your Mac, and launch Disk Utility. Go to the Utilities folder in Applications and double-click on Disk Utility to open it.

Erase the drive. Click on the external drive in the sidebar and then the Erase tab. In most cases, the format will automatically be set to macOS Extended and the scheme to GUID Partition Map. You can leave it at that. If you’re running macOS Mojave and will only use the drive with a Mac using Mojave, you can choose APFS from the Format menu. Give your drive a name and click Erase.

Then open Setapp desktop app and launch Disk Drill. If you haven’t already installed Disk Drill, get Setapp account and install the app.

Create a disk image of your drive

When Disk Drill opens, click Backup in the toolbar and choose Backup into DMG Image from the menu. In the next window, click OK, Let’s Do It.
Now, choose your Mac’s boot disk in the main window and click Backup. You’ll be asked where you want to save the disk image.
Navigate to the external drive you’ve just erased and select Save.

Disk Drill will now create an exact copy of your boot drive as a disk image, saved on the external drive.

Once the disk image has been created, you can double-click on it to mount it in the Finder. It will then be treated like any other volume by macOS and you can drag and drop files from it to your main drive. That’s fine if you only lose a few files and folders and need to recover them, but what if your boot drive fails or you need to recover the whole disk from the image?

Restore the clone

You can’t boot a Mac from a disk image, but you can restore the clone to your Mac’s boot drive if you need to. Here’s how.

Shut down your Mac
Restart in recovery mode. Restart your Mac while holding down the Command and “R” keys.
Erase your boot drive. Click on Disk Utilities in the Utilities application and then Erase. If the disk image you’re restoring from has macOS High Sierra installed, choose APFS from the format menu, otherwise, choose macOS Extended (Journaled). Give it a name and click Erase.
Restore the disk image. Still in Disk Utility, click on the drive you just erased. Now go to the File menu and choose Restore. Click the Image button and navigate to the disk image you created in Disk Drill. Then Restore.

Alternatively, if you know beforehand that you’re going to need to boot from the clone, choose Create Boot Drive and then Boot Drive for data recovery instead of Backup when you've created the disk image of your drive.

Recover files from disk image

If you don’t need to completely replace your Mac’s startup disk, but need to recover files from a disk image — perhaps because you created the image from a failing drive that has now failed completely — you also can do that in Disk Drill.

Create Dmg Mac

Mount the drive. Double-click on the disk image in the Finder to mount it.
Recover data in Disk Drill. Select the mounted volume in Disk Drill’s main window and click Recover. Follow the on-screen instructions to scan the volume, identify and recover the files you need. Remember that you should never recover files to a failing hard drive, so choose a destination that you know is stable.

You now know how to clone your Mac so you can use it as a backup for files and folders, as well as to recover files and, if you need to, boot from the clone and restore the image to your Mac’s startup disk. Let’s hope you never need it, but, if the tragedy comes around, at least you are prepared.
