Doing so will not affect your current MacOS Monterey system. Deleting the installer is primarily done to free up disk space, as it can take up several gigabytes. However, if you remove the installer, you’ll need to re-download it from the App Store should you ever need to reinstall or repair the operating system. Always ensure you have a backup before deleting system-related files.

What Happens When You Delete the Installer?

When you delete the “Install MacOS Monterey” installer, you are essentially removing the application package that contains all the necessary files to update or install MacOS Monterey on a Mac. This package is what gets downloaded when you obtain the update from the App Store, and it resides in your Applications folder until you decide to run it or remove it.

How it Affects Your System

Deleting the installer does not affect your current operating system if you’ve already completed the installation process. Your MacOS Monterey will continue to run just as it did before. However, you lose the convenience of having the installer readily available on your system for future use. For example, if you ever need to reinstall the operating system for troubleshooting purposes or to repair a corrupted system, you’ll need to download the installer again.

Risks Associated with Deleting the Installer

Generally speaking, there are minimal risks involved in deleting the installer:

  1. Inability to Quickly Reinstall/Repair: The most immediate risk is the loss of the ability to quickly reinstall or repair your MacOS Monterey setup. You would need to re-download the installer, which could be time-consuming and dependent on your internet connection.
  2. Potential Need for Disk Space: If you find yourself needing to reinstall MacOS Monterey, you will again have to allocate space for the installer, which can be a concern if you’re running low on storage.
  3. Version-Specific Installers: If Apple releases an updated version of MacOS Monterey that you don’t want to install for compatibility or other reasons, deleting your current installer means you’d have to be cautious about which version you download later.

Deleting the MacOS Monterey installer is generally a low-risk operation but comes with some trade-offs in terms of convenience and future-proofing. Always make sure you have a complete backup of your system before making such changes.
