How to Download macOS Sierra Installer Without App Store

macOS High Sierra is the latest version of Apple's operating system, offering improved photo organization, editing, and viewing in Photos. The new technologies at its core make your Mac more reliable, capable, and responsive, laying the foundation for future innovations. But what if you want to download the installer without using the App Store? This article will guide you through the process.

To download the macOS Sierra installer, you'll need to use a tool called gibMacOS. This handy little command line-based tool lets you download any version of macOS directly from Apple's servers, including test builds like developer and public beta releases. If you're an advanced user comfortable using Terminal commands, you can follow these steps.

First, download the gibMacOS tool from GitHub by clicking on the green code icon and selecting 'Download ZIP'. Extract the zip file to a folder of your choice. Once extracted, open the Terminal app on your Mac (you can find it in the Applications folder, Launchpad, or Spotlight search).

In the Terminal window, navigate to the gibMacOS-master folder inside the extracted folder by typing `cd gibMacOS-master` and pressing return. Then, type `./InstallAssistant.pkg` and press return again.

This will start the download process. You'll see a message saying 'Scanning for installer'. Once the scanning is complete, you can use the gibMacOS tool to download macOS Monterey (or any other version of macOS) directly from Apple's servers.

To do this, type `./gibMacOS -d macos-monterey` and press return. This will start downloading the full installer. Make sure not to put your Mac to sleep or close the lid until the download completes, as you'll need to restart the download otherwise.

Once the download is complete, you'll see a message saying 'Install finished successfully'. You can then find the full installer in your Applications folder or by opening Launchpad.

By following these steps, you can easily download the macOS Sierra installer without using the App Store. Just remember to be patient and not interrupt the download process until it's complete.
