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 Suite 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 Trash. 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 128GB 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.

Apple began transitioning to 64-bit hardware and software technology for Mac over a decade ago, and all modern Macs now include powerful 64-bit processors that can run advanced 64-bit apps. These apps can access dramatically more memory, enable faster system performance, and take advantage of technologies that define today’s Mac experience, such as Metal graphics acceleration.

Apple has been working with developers to transition their apps, and in 2018 Apple informed them that macOS Mojave would be the last version of macOS to run 32-bit apps.

Apple’s transition to 64-bit technology is now complete. Starting with macOS Catalina, 32-bit apps are no longer compatible with macOS. If you have a 32-bit app, please check with the app developer for a 64-bit version.

Opening 32-bit apps

When you attempt to open a 32-bit app, you will see an alert that the app needs to be updated to work with this version of macOS, or that the app is not optimized for your Mac and needs to be updated.

macOS Mojave and macOS High Sierra

If you haven’t upgraded to macOS Catalina, you can still open and use the app, but you should check with the app developer for a 64-bit version that also works with the latest macOS.

How to find 32-bit apps on your Mac

System Information can find 32-bit apps that are installed on your Mac:

Choose Apple menu  > About This Mac, then click the System Report button.
Select Legacy Software in the sidebar. All legacy software is 32-bit.
If you don’t see Legacy Software in the sidebar, select Applications in the sidebar, then check the list of apps on the right. The column labeled ”64-Bit (Intel)” shows ”No” for apps that are 32-bit.

When upgrading to macOS Catalina, the installer shows a list of recently used apps that are 32-bit. You can review this list before choosing whether to cancel or continue the installation:

macOS Catalina also shows a prohibitory symbol over the icon of each 32-bit app in the Finder, letting you know that the app will not open.

How to contact the app developer

The developer (or vendor) is the person or company that made the app. The easiest way to find contact information for an app’s developer is to search the web for their name or the name of their app. Learn more about contacting third-party vendors.
