Downloading macOS Mojave can get a little confusing because there are two types of downloads. One is the basic stub installer file that's about 22-23 MB, but the full size installer is about 5.8 to 6 GB. The stub installer does fetch all the other required content once you do the installation, but if you need the full installer so you can put Mojave on a different computer, then there are several ways to do that.

The legit way to download or install macOS Mojave provided by Apple is through Mac App Store, where you can get the macOS Mojave install app but it is can be used by other programs for installation.

In addition, you can also download the install dmg from other file hosting or torrent sites. This method is a little risky unless you know the website you're downloading from. For example, some websites that offer direct downloads for macOS Mojave will actually give you version 10.14.1, which is an update rather than the full OS installer. Others might even just serve you the stub installer.

To avoid this, try and read some genuine user reviews before attempting this approach. For that reason, there's no particular site that we recommend. However, that's not to say that there aren't genuine sites that offer the full installer. Most are free, but some might ask for donations via PayPal. If their version works out for you, it's up to you whether you want to pay them a small amount for their trouble.

p.s you need to burn mojave dmg to USB to make it a bootable media for macOS installation. After that, you can use the bootable USB to install macOS on the current or another Mac.

Use Download Manager to Get Mojave DMG Installer

macOS Mojave Patcher is a third-party utility that can be downloaded from the dosdude1 website, and is required to get the full 6GB DMG installer file for macOS Mojave.

As a first step, download the patch utility and run it on a Mac PC or laptop. Note that some Mac computers are not supported by this software, so check the list of compatible devices before getting the app. Within the app, click on the Tools option in the top toolbar and select Download macOS Mojaveā€¦ The keyboard shortcut for this is Command+D. You'll see a pop-up notification asking you to confirm the download. Click Yes to download the full installer, which should be around 6000MB.

Download macOS Mojave DMG Installer from Mac App Store

If all you need is the stub installer for an upgrade from an existing macOS installation, it's even easier because it's just a question of simple and direct download from Apple's servers. However, this version can't be used for a clean install on a different computer because it won't contain the needed applications to create bootable media on a USB or DVD. For that, you are better off using the first method.

Go to App Store app on your Mac and search for macOS Mojave, then click the Get button next to it. This file will be called Install macOS Mojave.app, and all you need to do is click the Download button in the Software Update utilitiy that automatically launches when you click on Get in the App Store. You will need to enter your Mac credentials when prompted.

Again, remember that this is merely the stub installer, so it's only useful for upgrading current macOS to Mojave, not able to do a clean install on a different computer.

Re-Download Mojave with Mojave Running

Another way to get the stub installer is when you're already running macOS Mojave on your computer. The process is the same as the one described in Method 2, so you can follow the steps described above.

In certain cases, however, this method won't work because the Get button might not be available. It might show you that the OS is already installed, which means the button is greyed out and basically useless to you.

Abort the Reboot after Running macOS Mojave.app

This method is a sort of gimmick that tricks the stub installer into downloading all the required files for a full installation, and then aborting the process right before your computer reboots to actually go into the installation. This is not for the feint-of-heart because it requires commands to be run in Terminal, the command line interface in Mac.

Get the stub installer from the App Store and run it. You'll see several prompts, which you just need to follow by clicking through each. When you see the countdown timer for the reboot, hit the Cancel button.

At this point, all the files for the full installer have been downloaded, but they still need to be packaged in order to work. For this, run the following three commands in Terminal (Applications > Utilities), clicking Enter after each one:
sudo -s
mkdir /Applications/Install macOS Mojave.app/Contents/SharedSupport
cd /macOS Install Data
find . -mount | cpio -pvdm /Applications/Install macOS Mojave.app/Contents/SharedSupport

Now go to the directory where you saved the original stub installer, and you'll see that it has magically turned into a 6GB file, which is the full installer.
