Check compatibility

The version of macOS that came with your Mac is the earliest version it can use. For example, if your Mac came with macOS Big Sur, it will not accept installation of macOS Catalina or earlier.

If a macOS can't be used on your Mac, the App Store or installer will let you know. For example, it might say that it's not compatible with this device or is too old to be opened on this version of macOS. To confirm compatibility before downloading, check the minimum hardware requirements:

• macOS Catalina 10.15 hardware requirements
• macOS Mojave 10.14 hardware requirements
• macOS High Sierra 10.13 hardware requirements
• macOS Sierra 10.12 hardware requirements
• OS X El Capitan 10.11 hardware requirements
• OS X Yosemite 10.10 hardware requirements

Edclub typing. Mac users often find their Downloads folder filled with disk images that they previously downloaded from the internet, files that – having already installed the apps – they forgot to delete after unmounting the image. As you may already know, installer files for macOS come with a DMG file extension – otherwise known as an Apple Disk Image – and are similar to ISO files.

To install an app – the majority of which just require dragging and dropping – users need to mount this .DMG file just as you might mount a CD when putting it into a CD drive, which makes its contents visible on the Mac. The required software is packed into a special bundle and carries an invisible “.APP” extension.

Users tend to forget about the existence of these disk images after they install the software. The same is true for iOS installer files (IPSW), although using .IPSW to apply an iOS software update is considered to be a more advanced function and therefore more appropriate for tech-savvy users. Even so, it can still happen that even advanced users forget about these storage-hungry installer files.

How To Remove Installer Files

Having one or two installer files in the Downloads folder shouldn't cause any issues unless these files occupy gigabytes of space – Adobe Creative Cloud installer packages, for example. But when you realize that your Mac is running out of free space, this is a good place to check for the remains of installer files to remove them and save space.

Removing these files is as easy as the installation process: select the file and drag it to the Bin. There are cases where the software is more complex, such as Adobe's suite of programs or Mac optimization software OnyX's installer files. If this is the situation, just open the disk image and look for an uninstaller file, or launch the app and find the uninstall options. The uninstall process may differ by app, but in most cases it is hassle-free.

Most Common Issues When Removing Installer Files

The drag and drop removal method, however, may leave some junk data behind since it doesn't remove the supporting files, which, if you frequently install and uninstall apps, may end up eating into your Mac's storage.

Ever since macOS Sierra 10.12, Apple has provided users with the option to trash the installer as soon as its function is finished, a pretty handy feature considering the limited disk space on a MacBook Air.

Fortunately, Mac optimization apps such as CleanMyMac and others include a neat uninstaller utility that helps remove all files associated with the application and its temporary installation files. While this feature won’t remove the installation file, it does find the files associated with specific software after selecting the app(s) that you want removed.

Installer files are easier to remove because they can be considered as .ZIP files. To move the installer to the Trash, however, you should first unmount it, otherwise it will display an error message. After unmounting it, locate the file (usually in the Downloads folder, the default location for files downloaded from the web), and simply press the Command + Backspace keys or drag it into the trash can.
