macbook pro os download dmg


The Mac app store is the best and secure channel to download macOS updates. It goes well if you have a stable and fast network connection. However, the download through the App Store doesn’t work at certain times, especially when your account has some billing issues. Sometimes Macs also get into internal software or hardware problems and may not boot up for unknown reasons. However, we can quickly recover a Mac and install macOS on multiple devices if we have a bootable USB installer. macOS full installer and macOS DMG help you create this USB disk from a Mac and Windows PC, respectively. If you are wondering how to download the macOS full installer, you can either get it from the App store or without the App store while being on your Mac. Then you can use the same installer to make a bootable macOS DMG file. This post explores various ways to download the macOS offline installer (APP, DMG & PKG) directly from Apple, all through legal methods.

How to download macOS full offline installer

Before going further, please be informed that if you are from the USA, you the macOS offline USB installer for Big Sur, Catalina, High Sierra, El Capitan & others from Amazon. These offerings are from third-party sellers who build USB installers from different macOS versions. So if your computer has a booting issue and needs an immediate fix, you can try buying these offline USB installers.

Downloading macOS full installer from the App Store

As said earlier, if you want to make a USB disk yourself, you need to download the macOS installer first. So let’s start with the direct App store links for all recent macOS versions.

These links automatically open the App Store once you click on them. Then press the “Get” button for the software update to fetch and download the macOS full installer.

As shown in the above image, you will find the full-size installer in your Mac’s Application folder once the download is over. Now, if you want, Apple’s website has some Terminal commands to make a USB disk from the downloaded macOS full installer.

Connect a USB drive of nearly 16GB size, copy-paste the required command to the Terminal app in your Mac, and commit it to create the USB quickly. Not forget to change the disk name from MyVolume to your device’s name.

Tip: If you are not familiar with Terminal and command-line tools, you may use an app like DiskMakerX or MDS (explained below) to build a bootable macOS  USB installer.

Download macOS Big Sur and Monterey (Public Beta) – direct link.

After the release of macOS Big Sur, Apple provides public and direct download links for macOS in PKG format. Hence, it is possible to download macOS Big Sur 11.16,11.15, 11.14, and macOS Monterey 12.0 Beta full-size installers to your Mac, Windows, or any internet-connected device. However, you need a Mac to install and extract this downloaded PKG file and save the macOS installer to your “Applications” folder.

Once you get hold of the InstallAssistant.PKG file, double-click on it, and complete the installation. After this, you may go to the “Applications” folder to find macOS Big Sur/Monterey full offline installer and use it for OS upgrade or installation.

Those who want to participate in the macOS Monterey Public Beta program may now sign-up for the opportunity from the Apple website. Then you may open up the go Software update and check for the Monetary download. Alternatively, people facing issues with the download may click the above direct link to save macOS Monterey 12.0 full installer to your Mac.

Recover M1 Macs and later with macOS IPSW firmware (offline installer)f11……..

If your Mac has an M1 chip, there is a version of macOS that comes in IPSW format, just like iOS. The recoveryOS (firmware) helps restore a Mac using the Apple configurator app (available on the app store) and a separate Mac.

Similar to iOS, M1 macs also have the feature that allows you to restore your faulty device using a downloaded IPSW file. You have to put your Mac in DFU mode and download the Apple Configurator app to perform the recovery. Connect the M1 mac to another Mac, run the Apple configurator, and drag and drop the macOS IPSW file to start the offline restore process. The complete set of instructions for reviving and restoring your M series Mac using the IPSW file is presented on the Apple website.

Alternative: download old & Beta versions of macOS using gibMacOS script.

A direct download link is not available for old macOS versions like Catalina 10.15, Mojave 10.14, High Sierra 10.13, etc. When someone requests these versions of macOS through the software update, Apple downloads the OS part by part to their Mac. The system then joins the OS files to form the macOS installer that we see in the Applications folder. Some apps and scripts can scan the Apple catalog and check which all macOS versions are currently accessible for download. If the user requests a specific OS, it can download macOS files from Apple and join them together to form offline installer. We have a video about one such tool, gibMacOS; have a look at the details below.

Check the later parts of the video (starting from 2.30) to see how we can take advantage of the “

gibMacOS

” script to download old macOS editions like High Sierra, Mojave, Catalina directly to your Mac. We have explained the steps to select and download the macOS versions and create the full installer using a second script.  

One thing we missed in the video is gibMacOS’s ability to download macOS Big Sur, and Monterey’s Beta and Developer builds. Just change the catalog (put option C in Terminal) to download macOS Beta full installers. The gibMacOS script can also run on a Windows PC. However, we can’t talk about it for for legal reasons; you can try it yourself.

How to download macOS DMG installer

DMG or Disk image is a conventional format used in macOS for distributing macOS installer and applications. DMG is a mainstream file type in older Macs.  Still, some old versions of macOS like OS X Lion 10.7, OS X Mountain Lion 10.8, Sierra 10.12, El Capitan 10.11, and Yosemite 10.10 are available to download in DMG format. However, presently, almost all applications have the .app extension when you download from the App Store.

Double-click on the downloaded file (on a Mac) to open and access the macOS installer. In Windows, you may use 7-Zip to extract it since DMGs are almost like ZIP or RAR, the archive formats.

The advantage of DMG is that it can hold multiple files in the package; the author can provide it to the user as a direct single-file download, suitable for internet transfer. Since it’s a disk image, we need to mount it to access internal files, and it also has properties similar to the ISO extension in Windows.

You can also use apps like MDS to download macOS offline installer as a DMG file, as shown in the above screenshot. Just like the gibMacOS, MDS can download macOS High Sierra, Catalina, Mojave, Big Sur, and Monterey, but in DMG format. Select the PublicSeed Catalog to see all available macOS versions. However, macOS DMG downloaded through MDS is not bootable; it’s a package of macOS offline installer, apps, settings, and some scripts. MDS can automate and install macOS on multiple Macs with pre-configured settings and apps.

Making bootable macOS USB installer drive with MDS

Another interesting feature of MDS is the option to create bootable USB installer for latest versions of macOS, especially the ones not supported by DiskmakerX. After downloading a macOS DMG using MDS, mount it and open “Applications” directory. Then copy the macOS full installer to a suitable location and then provide this directory in the “Create Bootable Installer” window of the MDS app. Finally, select a “Target Volume” as press the create button to build the recovery USB key.

Links to macOS DMG update installers.

Apple no longer provides the full installer of macOS in DMG format for OS updates after OS X Sierra. What they provide in DMG extension is the incremental security and supplemental updates for the already existing OS. That means the macOS DMG files listed on some sites are not the full-size macOS installer. They cannot be used to re-install or recover a computer. These macOS DMG files are actually offline update installers.

Get a DMG installer if you get the error message “macos update could not be installed” in the App store or if the software update download is stuck because of network issues or for any reason.

How to make bootable macOS DMG image from the full installer

In our column about making macOS USB in Windows, we tell about a special DMG file. This macOS DMG installer is the only hope when your Mac is faulty, and you got only a Windows PC at your place for any possible recovery. It has the boot files of a macOS USB made on a Mac. Hence, when you burn this image to a USB on Windows, it works exactly like a Mac-built USB. You can use third-party apps TransMac or Balena Etcher to complete this process.

The above video illustrates the step-by-step process to make bootable a macOS disk image in a Mac. You may also convert the output DMG file to a macOS ISO if wanted. Unfortunately, we can’t share them on our website as they are slightly altered versions of macOS. Therefore, if you encounter boot issues with your Mac and only have a PC at your place, get the help of someone who can make macOS DMG by watching the above video; they can easily send the DMG file to you through the Internet.

  1. Thanks a LOT for the effort you are taking to help all of us! I really appreciate it! I have an old mid2009 MBP currently running 10.6.8 on the internal HD and El Capitan on an external HD and now I am trying to install High Sierra on the external HD. Then I will try to move 10.6.8 to an external because I don’t want to lose some (a lot) important files , then will use the internal HD for High SIerra. Sounds a bit crazy, but I just love this old relic 🙂 So, Thanks again!

  2. I am trying to fix a friends Macbook Pro Mid 2012 with an old non solid state hard drive. I am not a mac person i am a pc person. This is a freebee job for a friend of a friend.
    She has no money nor do i. I updated her hard drive to a solid state 500 gig drive and partitioned it and formatted it and installed High Sierra on it. When i did this i ran into the date issue because the certificates had expired. I tried changing the date in terminal but never could get it to work. I don’t have access to the app store because her macbook pro running Mountain lion would not boot because the boot partition of her old drive was damaged. I got a bootable image of El Capitan and it installed until it got to the update over the internet problem with authorization. I think my biggest problem is the dates have expired on these versions of OS X. I found a page where Mac finally updated their certificates to expire in 2029 but the links to them are all on mac app store which i can’t access! Do you or anyone know where i can download one of these updated versions of OS X other than the Mac App Store? I have spent way too many hours working on this issue! Please help if you can!

  3. Do you have an offline version for catalina? If so that would be fantastic

  4. Thanks for your effort to provide such a handy service.
    I would appreciate if you could help me with my Mac mini mid 2011 with 10.13.6 installed which got stuck after an upgrade.
    I don’t have another Mac machine to create a bootable USB drive to reinstall the OS.
    I looked around for ways to create the bootable drive for the Mac mini with a Windows machine but nothing worked so far.

  5. I’m trying to go from high sierra to catalina but it’s all big sur now. How can I get the initial catalina dmg file? Thanks.

  6. Hi how can i upgrade my currunt os is el captain 10.11.6 & couldn’t find sierra

    • Hi Tuan, these DMG files are incremental updates installers. You need to login App store for the full OS upgrade. We have direct link to the macOS Sierra in the article — please check.

  7. When I double-click on the macOsupdcombo10.14.6.dmg it says the file is damage…

  8. The High Sierra 13.6 (Final combo update) link is dead. Is it possible to fix it or is this no longer available for download ?

    • Thanks for the comment. We have updated macOS High Sierra 13.6 dmg link.

  9. Mojave is no longer available via the app store at all — despite having five other machines running it. Any suggestions for where to get the full installer to move up from High Sierra?

      • Hey it is possible. Just download Doddude’s Mojave patcher. Link is given just before the comment section. It has the option to download Mojave 10.14 installer directly to your desktop without app store.

  10. I have tried many ways to collect the official macOS .dmg or .app but failed for some old versions, like High Sierra, Sierra. For Catalina and Mojave, they get the official supports from App Store currently, so it’s not a problem.

    I tried your way. It worked until High Sierra. when it came to Sierra, failed.

    Anyone can distribute some collection of macOS.dmg or installation.app by bittorrent? so that this collection will be alive in P2P world forever!

    PS: why do you ban the input of “p” and “, “? All these two letters I input above are by PASTING

  11. Do you have direct links to older versions in the store? Like all the way back to Lion?

      • Hi guys
        I’ve sent you an email. Anyway I’d like to have a full High Sierra installer to restore my mac mini accidentally dead after a ba update. It’s in a rebooting loop. I can see the recovery menu but actually the latest recovery doesn’t work. So I’d like to try with a full reinstallation but I can’t find the OS. I’m trying with a mountain lion by a USB-disk and even if the mac see the drive and try to start the installation then it freezes in a white screen and I have to power off.
        Thanks and regards
        Dario
