How to Re-Download MacOS Mojave Installer (from MacOS Mojave)

How to Redownload MacOS Mojave installer

Some users may occasionally need to re-download the MacOS Mojave installer application while actively running MacOS Mojave. This is usually done for making a MacOS Mojave boot installer drive or some other similar purpose, or perhaps to copy the installer onto another computer or as a backup, but there are other reasons someone may want to download the “Install MacOS Mojave.app” package again too.


Remember, the MacOS Mojave Installer application deletes itself automatically after macOS Mojave has successfully installed, thus even if you previously downloaded the installer and used it to install Mojave on the same Mac, unless you previously had made a copy of it then it will have removed itself, thus you’d need to re-download it again.

How to Re-download the MacOS Mojave Installer Application

  1. From MacOS Mojave, open the Mac App Store and search for “MacOS Mojave” (or click this direct link to Mojave)
  2. Click the “Get” button to start re-downloading MacOS Mojave

  4. The Software Update control panel will automatically launch, confirm that you want to download MacOS Mojave to download the installer

The installer package when finished will land in the /Applications folder as it normally would, labeled as “Install macOS Mojave.app”.

The Installer application for MacOS Mojave

This process may be a little confusing because while the installer for MacOS Mojave comes from the Mac App Store, later system software updates arrive through the “Software Update” preference panel in MacOS Mojave 10.14 onward.

Help, I can’t download MacOS Mojave from the Mac App Store!

If you can’t get the Mac App Store method of re-downloading the MacOS Mojave installer to work properly for whatever reason, then not to worry because there are other methods available.

The same trick that is used to navigate around the mini-Mojave installer can also be used to download the full size macOS Mojave installer directly from MacOS Mojave 10.14 or later as well.

That alternative method, which uses a third party utility to download and build the installer package, should work regardless of what you can or can’t get working from the Mac App Store approach.

    No, it does not work.
    I have installed macOS 10.14(18A391) and when I try to redownload the installer, after it downloaded 6.02GB file, I can’t find it anywhere including usual /Applications folder.
    It is so weird on Mojave and so annoying.

      Strange, it works to redownload macOS Mojave installer for some people obviously, but not others? The pictures clearly show it working too, did you do something different than instructions?

      Use the Dosdude1 tool, it downloads the installer as well. I had to use it on a Mac with El Cap which got the micro install file.

      Apple is sometimes confusing today, sad! Same instructions work for some, but not all, that makes no sense!

    I downloaded macOS 10.4 Mojave direct from Apple’s Servers. However I normally wait until the second or third update.

    I was so eager to see macOS 10.14, instead of downloading it to my 2015 MacBook Pro Retina, I chose to install it on an external USB 3 Hard Drive. The download went well as I have a download speed of over 350 Mbps. After downloading 10.14, it took nearly an hour to complete the installation. When I tried to boot from the external HD, the Mojave desktop appeared after a PRAM reset and a Recovery Mode restart. What have I done wrong and is there any help you can offer me.

    Many thanks,

      It sounds like you have macOS Mojave running on the external drive and it’s working. Why it required a PRAM reset is not sure, maybe your USB was not being recognized?

      Hold OPTION key at boot to switch between booting your Mojave external drive, and the internal drive.

      But I am like you, I usually wait for second, third, or later updates… Mojave included.

    It went well nicely with my Macbook pro early 2015 RD
    I made a bootable pen drive and clean installed the Mojave.
    Everything is fine.
    but once I switch on the mac book the mojave screen apears and then I put in my password it boots and while booting the mojave screan disappears and a black screen appears and then desk top appears.
    Is this Normal?

    Hi,

    Thanks for your quick reply. Yes I am using Mojave on a USB 3 external drive. It will boot from the external HD, holding the the Alt key dow I get the Mojave desktop, then everything. I was advised by Apple Support to do a PRAM reset, don’t know why but I think it’s now called a VRAM rese now. I have 150 GB USB stick. I could download Mojave onto that. I think I’ve read on your site that Mojave sometimes needs to be installed twice.

    When I upgraded to High Sierra direct to my MacBook Pro Retina, but somehow it asked for the Firmware password, which although I’ve been on Mac System since 1992 on System 7.6 I’ve never know a firmware password. It had to go back to a UK Apple Authorised Technician. It was only 4 weeks out of AppleCare, but I had to pay £90 plus carriage. Pity I didn’t have access to your article on getting a new firmware password before that. I believe it’s stored in a chip on the logic board, so perhaps, a task not to be attempted by a 77 year old with MS & chronic arthritis in his hands

    Will keep you posted,
