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.

Download CleanMyMac X from MacPaw’s website and clean up to 500MB of junk data from your computer while enjoying all the features of the software without major limitations.

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

When you try to uninstall some of the pre-installed applications – “ Chess ” or “ GarageBand ” for example – by dragging it to the trash will make your Mac prevent you from doing so and a message makes clear that the application cannot be modified or deleted because it’s required by Mac OS X.

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.

How to remove MacKeeper from Mac?

What is MacKeeper?

Developed by Zeobit and then acquired by Kromtech, MacKeeper is a legitimate and useful application for Mac users. It provides functionality that allows users to optimize and increase system performance. Despite this, some MacKeeper affiliates employ dubious/unacceptable measures to proliferate this software. Therefore, it can be classed as potentially unwanted program (PUP).

This application is proliferated in various ways. It has an official download website, which is fine as a legitimate app, however, as mentioned above, some criminals proliferate this program in dubious ways. For example, they develop malicious websites that display fake error messages claiming that the system is corrupted. To resolve these 'issues' (that do not exist), users are encouraged to download MacKeeper. The list of dubious sites includes (but is not limited to) Virus Found and We Have Detected A Trojan Virus. Criminals also proliferate this application using intrusive advertisements (pop-ups, banners, etc.) and a deceptive marketing method called 'bundling'. If you feel that MacKeeper has infiltrated systems without your consent, follow the guide below and remove this application.

The aforementioned methods are also used to proliferate other PUPs that are not legitimate (e.g., adware, browser hijackers, etc.) Most generate intrusive advertisements and record various sensitive data. The ads are delivered using various tools that enable placement of third party graphical content on any site. Therefore, they often conceal underlying website content, thereby diminishing the web browsing experience. Most PUPs are also designed to gather various information that typically includes personal details. Internet Protocol (IP) addresses, Internet service providers (ISPs), geographic locations, URLs visited, pages viewed, queries entered into search engines, keystrokes, and other collected data is later sold to third parties (potentially, cyber criminals). These people generate revenue by misusing private information. Therefore, the presence of information-tracking apps can lead to serious privacy issues or even identity theft. We highly recommend that you remove all dubious applications and browser plug-ins.

All potentially unwanted programs are very similar. By offering a number of features, PUPs such as MyShopcoupon, TURBOMAC, and others, attempt to give the impression of legitimacy, however, their only purpose is to generate revenue for the developers. Only a small percentage give the features promised - most are useless. Rather than (or together with) enabling the functionality promised, potentially unwanted programs pose a direct threat to your privacy and Internet browsing safety.

How did MacKeeper install on my computer?

As mentioned above, MacKeeper is proliferated using intrusive ads, together with the 'bundling' method. Intrusive ads redirect users to malicious websites and/or run scripts that download/install PUPs. Therefore, even a single click might result in inadvertent installation of certain applications. 'Bundling' is stealth installation of PUPs together with regular software. Developers hide 'bundled' apps within 'Custom/Advanced' settings (or other sections) of the download/installation processes. Many users rush these procedures and skip steps. In doing so, they expose their systems to risk of various infections. The main reasons for computer infections are poor knowledge and careless behavior.

How to avoid installation of potentially unwanted applications?

To prevent this situation, pay close attention when browsing the Internet and, especially when downloading/installing software. Bear in mind that criminals invest many resources into developing intrusive ads. They often seem legitimate, but are distinguishable, since most lead to survey, gambling, pornography, and other dubious websites. As mentioned before, intrusive ads are typically delivered by PUPs and, thus, if you encounter them, immediately remove all suspicious applications and browser plug-ins. Select 'Custom/Advanced' settings, carefully analyze each window of the download/installation procedures, and opt-out of all additionally-included programs. You are advised to download software from official sources only, using direct download links, since criminals employ third party downloaders/installers to proliferate ('bundle') PUPs. Using a legitimate anti-virus/anti-spyware suite is also paramount. The key to computer safety is caution.
