Downloading and using different Mac OS installers is very common for troubleshooting purposes, for IT staff and admins, and for tinkerers. This article will discuss where to download and access installers for MacOS Monterey, macOS Big Sur, macOS Catalina, MacOS Mojave, MacOS High Sierra, macOS Sierra, Mac OS X El Capitan, OS X Yosemite, OS X Mavericks, Mac OS X Mountain Lion, Mac OS X Lion. How to make a macOS bootable USB installer. It is possible to create a backup macOS installer on a DVD or USB drive but later is the best choice. Most of the Macs these days don’t have DVD slots, and the installation through a disc is very slow. Hence we discuss only about making macOS recovery installer on a USB disc.
When I originally downloaded the
Install macOS Mojave.app for the original release 14.0.22, I got a 6.03 gig file.
Today I replaced that file by downloading the installer fresh from the App Store for 14.1.0. The app is only 22 megs! So obviously this is just a shell that I imagine downloads the needed content over the internet at runtime.
But I need an offline installer, for clean-installs on various Macs and for creating virtual machines.
➥ How to obtain fully-loaded offline installer app for Mojave 14.1.x?
What about just using the original installer, then updating immediately the newly installed OS to .1? That .1 update was a whopper, over 3 gigs! I really want to avoid repeating that updater download. I really need a fully-loaded offline installer.
The 22 MB 'stub' installer is downloaded when your Mac is having trouble getting the correct data from Apple's software update catalogs. This is quote common during the first 24 hours or so, as it takes a little while for the updates to propagate across the CDNs. The solution in this case is to delete the stub, wait a couple of hours, and then try again.
There is also a useful script by Greg Neagle that lets you inspect which installers are available in your update catalogs, and can download them for you: installinstallmacos.py
PS: If you have a Mac managed by an organization, you may also get the stub installer if your administrator hasn't approved the new update, e.g. with Reposado.
You can easily download the full
14.1.0 installer using this tool: macOS Mojave Patcher Tool.
Start the tool, and then go to
Download macOS Mojave... and select a download location.
After the download is complete, it will ask you if you want to create a patched usb installer, simply click
Not Now as you don't need a patch (except if you want to install on a very old mac).You can safely quit and remove the tool, as you no longer need it.
Here you are:
Attempting to download macOS Mojave from the Mac App Store I found that a small 22 MB version of the “Install macOS Mojave.app” file downloads to the “Applications” folder, rather than the complete 6 GB installer file.
The tiny 22 MB incomplete installer requires an internet connection during usage to download the rest of the Mojave update files. Additionally, it does not allow to create a macOS Mojave USB installer drive for use on multiple computers.
In this tutorial, I’ll show you how to download the complete “Install macOS Mojave.app” file from Apple servers using the “macOS Mojave Patcher” app instead of via the Mac App Store.
A similar mini-installer issue occurred previously with some users getting a tiny incomplete macOS High Sierra installer too and I covered a similar workaround here to download the complete installer file from Apple servers.
In this workaround, we’re going to use the macOS Mojave Patcher app from the dosdude1.com. This app is intended for those with unsupported Macs and Hackintosh users, but any Mac user can use the app to be able to download the complete macOS Mojave installer file from Apple servers. For our purposes in this particular walkthrough, we will use the app only to download the complete installer file.
Note! This method relies on a third party app from an unverified third party source. If you are not comfortable with using unvetted and unverified software, do not follow this process.
Downloading the complete “Install macOS Mojave.app” file from Apple servers using the “macOS Mojave Patcher” app is a really easy process. Now, step by step guide.
Go to the official website of the “macOS Mojave Patcher” app here and download the app.
The download links are labeled as “Direct” and “Mirror” on that page.
Launch the “macOS Mojave Patcher” app.
Note! By default, macOS preventing apps from unidentified developers or sources from being launched. So you most likely will get an alert message that says: “macOS Mojave Patcher.app can’t be opened because it is from an unidentified developer”. To allow just one specific app to run do the following:
Controlkey and click the app icon. From the contextual menu choose
Ignore everything about patching, instead pull down the “Tools” menu and choose “Download macOS Mojave…”.
Confirm that you want to download the “Install macOS Mojave.app” app, and then point it to a location to save on the hard drive.
Close the “macOS Mojave Patcher” app when the download is complete and locate the “Install macOS Mojave.app” file you downloaded.
That’s it, you’re done. Now you have the complete “Install macOS Mojave.app” file downloaded. So simple isn’t it?
You can confirm that you have the complete “Install macOS Mojave.app” file by getting info on the file. For this simply select the file and click the
Spacebar key (or right-click on the file and choose “Get Info”). The complete installer should be around 6 GB rather than the tiny 22 MB incomplete installer that requires additional downloads.
Note! Remember, the “Install macOS Mojave.app” file deletes itself automatically after macOS Mojave has successfully installed. Therefore, you may want to make a backup by having previously copied it to external storage.
Let me know in the comments section if you know another way to download the complete “Install macOS Mojave.app” file rather than the tiny incomplete installer.
I hope this article has helped you learn how to downloaded the complete “Install macOS Mojave.app” file from Apple servers. If this article has helped you then please leave a comment
