You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful if you want to install macOS on multiple computers without downloading the installer each time, or you're unable to install a compatible macOS from the Finder or macOS Recovery.
Simply drag and drop files onto the window view, give your disk image a background image, and click Build. What you see in DMG Canvas is exactly how it will look in Finder. You can create great backgrounds for your disk images right inside DMG Canvas itself by dropping in images and adding stylized text, and you're done in a snap.
We've all seen the license agreements required to click-through when mounting a disk image, but it is a nightmare trying to do it yourself. Let DMG Canvas take care of it for you. If your company wants to ensure the user has seen the license agreement upfront, it's a piece of cake. Just put your license's text into DMG Canvas and you're done. It even supports styles and multiple languages.
Flip back and forth to view how the disk image will appear in macOS Light and Dark modes to ensure it looks good in both. Disk images with no background set at all will use the Finder window's appearance and change change depending on the user's system appearance setting. In Dark Mode, the window background will be a dark-gray and file names will be displayed with a white color.
DMG Canvas goes the extra mile and carefully creates disk images with compatibility so they look and work great all the way back to OS X 10.4 if you choose, regardless of which version of macOS you're using. Or, choose the newest compression and file format options like LZMA and APFS, and have lightning fast disk image mounting times.
Add beautifully crisp Retina images and text to your disk images and DMG Canvas automatically handles creating the right image with multiple representations. More importantly, your users (and potential users) will see your attention to detail before they even launch your application for the first time.
Ensure your customers and macOS itself know that the disk image is safe and secure with code signing. Gatekeeper in macOS enables extra security features if your disk image is not code signed, potentially breaking behaviors in your application. Using DMG Canvas, code signing is as easy as a single click.
Since macOS Catalina, a new security feature called Notarization requires new application to be notarized by Apple to ensure they are not infected with malware. To help with this, DMG Canvas can easily notarize the disk image and its contents, and still maintain backwards compatibility with older versions of macOS. (Notarization requires that Xcode be installed.)
Even though clicking the "Build" button in DMG Canvas is a piece of cake, why click it if you don't need to? By using the dmgcanvas tool, you can integrate building your disk images into your normal build workflow, such as building an application in Xcode, so you won't even have to think about making a disk image; It's already done for you. And to satisfy macOS's Gatekeeper, you can now code sign your disk images with your Developer ID certificate, avoiding troublesome Path Randomization.
Not only can you integrate DMG Canvas into your own build scripts and workflows, but DMG Canvas itself can generate a script that will integrate it into your Xcode project! Drop in your Xcode project and DMG Canvas document, pick a few settings, and the script is there in a flash. Drop the script into your Archive scheme's "Post-action" script and then every time you Archive your application in Xcode, it'll automatically create a disk image ready for you to ship to your users.
The completed macOS installer will be located inside a disk image under an Applications folder. It is named Install_macOS_version-build.sparseimage Double-click on the disk image to see the installer.
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:
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.)
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.
A disk image on Mac is a file format that mimics a physical disk. Like physical disks, it can be mounted in Finder, where it looks like any other volume, have files and folders copied to and from it, and can be cloned or burned onto physical media like a CD or DVD. Disk images are ejected in the same way as physical disks and show up in Disk Utility. You can also use Disk Utility to create disk images of your own.
Note: Where are Docker images stored on the host machine? This question has answers related to linux machine, mainly. The answers for Mac OS X are considering that boot2docker is being used alongside docker installation, which is not the case for me.
Note: I have also added this answer to this question: Where are Docker images stored on the host machine? but I am answering here as well so that it's easier to find the answer for someone specifically looking for Mac OS X and new version of Docker.
R-Drive Image is a potent utility providing disk image files creation for backup or duplication purposes. A disk image file contains the exact, byte-by-byte copy of a hard drive, partition or logical disk and can be created with various compression levels on the fly without stopping Windows OS and therefore without interrupting your business. These drive image files can then be stored in a variety of places, including various removable media such as CD-R(W)/DVD, Iomega Zip or Jazz disks, etc.
R-Drive Image creates images on-the-fly, that is, without the need to restart Windows. Image files can be written to any storage places visible by the host system, including removable and network drives.
R-Drive Image files may contain images of entire hard drives, individual partitions, individual files, and even several unrelated disk objects. Data in such files may be compressed, password-protected, commented, and split into several files. R-Drive Image uses volume snapshots to create consistent point-in-time disk images. Image files can be checked for errors to ensure full data integrity. This check can be performed for both already existing images and new images automatically after their creation.
R-Drive Image restores images or individual files and folders from images to original drives, new drives, any other partitions, or even to free hard drive space on the fly. Partitions, being restored can be resized, and existing partitions can be deleted and/or erased, moved, or resized. Entire hard drive images can be restored to another drive, shrinking/expanding as needed.
It goes without saying that you will need an internet connection to download the software and you may need it while installing the version of macOS if it needs to check for firmware or confirm your iCloud credentials.
You can also run the Mac operating system directly from an external drive rather than your built-in startup disk, this is handy if you are testing new versions of the Mac OS. The process is different to the one described above though, and we cover it here: Read about How to run macOS on an external hard drive here.
I am running docker on Mac High Sierra ( version 10.13.3) . docker inspect on my container shows path is /var/lib/docker .But there is no such folder created. Could some one help with image location on Mac pls. And also why docker inspect shows different path? Am i missing something here ? Logs below
