Apple’s system updates have greatly improved over time. And though you’re less likely to face issues (slow downloading speeds, unable to resume download, frequent disconnections, etc.) while downloading macOS Catalina this year, there’s no guarantee that they won’t happen at all.
- MacOS Sierra and El Capitan download as a disk image that contains an installer named InstallOS.pkg or InstallMacOSX.pkg. Run this installer before continuing. If downloading macOS Catalina, macOS Mojave, or macOS High Sierra for the purpose of creating a bootable installer, your Mac must be using macOS Sierra 10.12.5 or later, or El Capitan 10.
- The download file is named 'cotvnc-20b4.dmg'. Here are the steps needed to install it remotely from the command line. Note: this technique can be used from a local Terminal window or a remote SSH connection. Mount the disk image. The first step is to mount (or attach) the disk image. From the command line, use: hdiutil mount cotvnc-20b4.dmg.
- New Mac owner here, but long time Linux user. Can anyone describe to me the differences between installing a piece of software, such as Subversion, from a.dmg image as opposed to compiling and installing from source on the command line? Does the software end up in the same location? What other differences exist, such as uninstallation procedures?
Many users would still be looking for direct downloads for macOS Catalina, primarily for multi-threaded, faster downloading via download managers & accelerators, resume support for incomplete/interrupted downloads and many more reasons.
May 16, 2018 So you’re running Linux on your computer, maybe Ubuntu, and you have some files with the.dmg extension. In this guide, we’re going to talk about how to open, mount, extract, and otherwise get your files from these pesky DMG images. I want to install a dmg file on a remote server. All I have is an ssh access. Since a DMG is a disk image, I tried to mount it, but mount does not seem to recognize its format. File says my dmg file is a VAX COFF executable.
In this article, we’ll explore a way to download macOS Catalina directly from the Apple server instead of via the MAS, using your favorite web browser or a download accelerator.

Download and install macOS Catalina without MAS / System Preferences
Since macOS Catalina, OS updates are delivered through the Software Update menu in System Preferences. When you try to download macOS updates via MAS, you’re automatically redirected to the Software Update menu.
Oct 24, 2019 Mac Pro introduced in early 2008 or later Xserve models introduced in early 2009. To find your Mac model, memory, storage space, and macOS version, choose About This Mac from the Apple menu. If your Mac isn't compatible with OS X El Capitan, the installer will let you know. How to download el capitan on mac. To download Mac OS X El Capitan from the App Store, follow the link: Download OS X El Capitan. On the El Capitan, click the Download button. Next, a file Install OS X El Capitan will download into the Applications folder. When the download is over, the installer will launch automatically. To proceed with the installation, select Continue and stick to the on-screen instructions.
In macOS, when you click on the Update button, some package files are downloaded to your computer, and then processed by the Software Update utility, to convert them into an executable “.app” file. You cannot install macOS directly from the raw package files.
For this workaround, we’re going to directly download these raw packages from Apple server using a web browser or a suitable download accelerator. Then, we’ll configure the computer in such a way that Software Update processes the package files by fetching them from a local directory on your Mac, instead of downloading it again from the Apple Server.
macOS Catalina Direct Download
Step 1: Download the three “.pkg” files from the respective URLs given below.
Command Line Tool Mac
macOS Catalina 10.15.1 (19B88) / October 29, 2019 (Updated)
- macOS Catalina InstallESDDmg.pkg file download URL: http://swcdn.apple.com/content/downloads/61/56/041-83630-A_8RCIBB415Y/7jqh3nh97ood2mjej7hdgpx7fgh5c3fi9g/InstallESDDmg.pkg
- macOS Catalina RecoveryHDMetaDmg.pkg file download URL: http://swcdn.apple.com/content/downloads/61/56/041-83630-A_8RCIBB415Y/7jqh3nh97ood2mjej7hdgpx7fgh5c3fi9g/RecoveryHDMetaDmg.pkg
- macOS Catalina InstallAssistantAuto.pkg file download URL: http://swcdn.apple.com/content/downloads/61/56/041-83630-A_8RCIBB415Y/7jqh3nh97ood2mjej7hdgpx7fgh5c3fi9g/InstallAssistantAuto.pkg
Step 2: Configure your Mac so that Software Update looks for the macOS packages locally instead of from the Apple server.
To do this, you need to edit the hosts file on Mac to point the root domain of the download URLs (“swcdn.apple.com”) to localhost (“127.0.0.1”). The below instructions will guide you to modify the hosts file as required.
- Launch Terminal on your Mac from Launchpad or Applications list.
- Type in the following command: “sudo nano /etc/hosts”
- Provide the System Password when prompted. The hosts file is now open in editable mode within the Terminal window.
- Append the following line to the end of the file: “127.0.0.1 swcdn.apple.com”.
- Press control + X (^X), then Y and hit return to save the file and return to Terminal prompt.
From now on, any request issued for the particular root domain (swcdn.apple.com) from the Mac will be directed to localhost.
Note: Sometimes, you might need to flush the DNS cache for the changes to take effect. In that case, use the “sudo killall -HUP mDNSResponder” command to flush DNS cache.
Step 3: Place the package files in a certain relative path from the localhost root, to mimic the structure of their respective download URLs.
In this example, we’ll create a folder named “macos_local” on Desktop, and replicate the directory structure of the package URLs under the same. Once the relative path has been created, we’ll configure the localhost server to point to the “macos_local” directory on Desktop. Then, we’ll use macOS’ built-in SimpleHTTP server to convert the folder into a web server directory.
The below instructions will guide you through the setup process.
- Open Terminal from the Launchpad or Applications list.
- Type “cd Desktop” on the command line and hit return to enter the Desktop folder.
- Type “mkdir macos_local” and hit return to create the root directory of the same name on Desktop.
- Go to the newly created folder by typing “cd macos_local” and hitting return.
- Enter the following command to create the relative path for the .pkg files, inside the macos_local folder (Provide the admin password when requested):
“sudo mkdir -p ./content/downloads/61/56/041-83630-A_8RCIBB415Y/7jqh3nh97ood2mjej7hdgpx7fgh5c3fi9g/” - Place the downloaded package files in their respective relative location (as per their URLs) within the macos_local folder on the Desktop. Click on Authenticate when prompted, and provide the system admin password.
- With macos_local as the present working directory in Terminal, execute the following command: “sudo python -m SimpleHTTPServer 80”. Provide the admin password and click on Allow in the subsequent message prompt.
The current directory (macos_local) is now hosted on localhost. Leave the Terminal window open to keep the localhost server running until the process is completed.
To verify the setup, click on any of the package (.pkg or pkg) URLs in your browser and check the download speed as it downloads the package.
You may notice a very high-speed download (which is much higher than the speed of your Internet connection). This is because the file will be downloaded through localhost; your Internet bandwidth won’t be used.
Step 4: Download macOS Catalina through the Mac App Store or System Preferences.
Winrar para mac dmg. Don’t worry. Since you’ve redirected the package URLs locally, Software Update / MAS will fetch the package files from localhost and launch the installer (“.app”) file once the packages have been processed.
Note: Your Mac might request additional resources from the “swcdn.apple.com” domain while installing macOS Catalina. Thus, it is recommended to remove the entry from the hosts file that we appended earlier, before proceeding with the installation.
Is the workaround genuine?
In this workaround, we are downloading the required resources from the Apple Server and using the official Software Update channel to install the OS update. So yes, it is as genuine as the official method.
The only factor we’re changing here is the location where Software Update / MAS fetches the packages from. If you are downloading the macOS package files from third-party sources, you can verify whether it’s the original, by comparing their MD5 and SHA1 hash values.
macOS Catalina Bootable Installer (macOS Catalina DMG)
Now that you have the “macOS Catalina.app” installer, you can upgrade multiple Macs to the latest version using the same file. However, if you are looking to perform a fresh installation, you need to create a bootable installer for Catalina.
The bootable image for Catalina (InstallESD.dmg) is located within its “.app” file. To get the InstallESD.dmg file, right-click on “macOS Catalina.app”, select “Show Package Contents” option, and browse to the “Contents/SharedSupport/” folder.

Alternatively, the bootable installer for macOS Catalina may be directly created from the “.app” file using the “createinstallmedia” command, as suggested by Apple.
