Mac users have enjoyed a long run of fairly virus-free computing, but it shouldn’t be taken for granted that there is no virus. While Apple has kept a close grip in the App Store, some malware, on rare occasions, still make it up there. Likewise, the macOS Gatekeeper is only useful when you do not override its settings, but that will restrict you to only install apps from the App store. So if you download an app that didn’t come from the App Store, how can you check whether it is safe to install?

Suspicious Package is a special-purpose utility program designed to check macOS packages – software files that install application programs. Packages typically contain several components, including the app itself, scripts that automate the installation process, and other files the program needs. Although the macOS packaging system is an efficient way for developers to organize all the pieces that go into an app, it’s also possible for hackers to subvert it by inserting their own malicious programming. Suspicious Package allows you to inspect the contents of any macOS package, potentially heading off a malware infection.
The Suspicious Package app is available for download directly from mothersruin.com. To install it, you may have to temporarily bypass the macOS Gatekeeper which normally prevents you from installing non-App Store programs by accident. In “System Preferences” go to “Security & Privacy -> General -> Allow apps downloaded from:” and change the setting to “App Store and identified developers.” When you open the Suspicious Package dmg file, you’ll see the warning, “SuspiciousPackage.dmg blocked from opening because it is not from an identified developer.” Click the “Open Anyway” button to install the program.
The “Quick Look” feature displays a package summary from the Finder without having to launch the Suspicious Package app itself. This is a handy time-saver if you have several packages to check. To use Quick Look, highlight the package you want to evaluate from the Finder, then find the Quick Look item in the Finder’s File menu, or press “command + Y.”
To check a package you’ve downloaded, launch Suspicious Package. From the “File” menu, select “Open,” then browse your Downloads or other folder for a package file to inspect. Suspicious Package analyzes the file, then displays a set of tabs: “Package Info,” “All Files,” and “All Scripts.” If the app detects problems with the package, the Review icon indicates a warning.
The Package Info tab gives an overview of what’s in the package. It shows how many items are installed, how many scripts it uses, and whether it is signed or not. It lists when the package was downloaded and the browser name. Finally, if the package has problems, Package Info shows the number of warnings given.
Resembling a Finder window, All Files shows all the files stored in the package, including the application itself, supporting files, and folder organization. Click on any folder to see its contents.
The All Scripts tab lists all the macOS shell scripts used to install the package. Each script is a mini-program containing text commands used to copy, create, and delete files. Click on a script name to see the instructions. The File menu includes options to edit a script, should you want to.
When using Suspicious Package, you may see a warning that says the package isn’t signed. Package signing is a feature Apple developed so software developers can “stamp” their programs with a digital signature officially tying the application to the people who wrote it. The signature gives confidence that the software is legit and not a cheap knock-off. In fact, Apple requires signatures for all software in the App Store. Some developers, however, don’t spend the extra effort needed to sign their software. Many unsigned packages, including open-source and freeware programs, are actually okay to use. On the other hand, if you’re buying Mac software from a major vendor, the absence of a signature is a big red flag.
The vast majority of Mac programs are free of malware. However, programs downloaded from third-party sites carry a small risk of spyware and other unwanted baggage. Though primarily aimed at technical users, Suspicious Package lets anyone evaluate macOS software for malware and other problems. The app clearly reveals the contents of a software package before you install it. Especially for Mac people who don’t use the App Store as their only source for software, Suspicious Package makes a worthy addition to your Mac toolbox.
A DMG file is used to compress and store data on a Mac. It helps in using up less disk space than if the data wasn’t stored in a DMG file. This is exactly the same as what happens with zipped files on a Windows computer system. A DMG file is also known as an Apple Disk Image file, or a Mac OS X Disk Image file.
DMG files are mostly used for storing the software installation media for a Mac, rather than the user requiring a disc. Another key attribute of a DMG file is the checksum, which actually is the verification of the content’s integrity. Once the checksum has been successfully verified, only then the file will go on to decompress the data included inside it. DMG files made their debut from OS X 9, and have proved to be highly popular since then.
This was just a brief intro about DMG files, now let’s focus on how to get rid of duplicate DMG files from your MacBook.
First up is the easier, straightforward and moderately reliable solution. It requires you to type in the extension (.dmg) in the right place and let your MacBook dig out all the dmg files for you. Once the whole list of duplicates has been compiled and presented to you, you have to give your verdict about any duplicates and move them to the Trash.
Sounds all simple, and good. But this method of searching up duplicate DMG files has its own fair share of downsides.
This method is totally reliant on the filename. If 2 DMG files share the same name, this method determines them to be duplicate. The reality might well be just the opposite, and so this method cannot be totally trusted upon at all. This is, unless you can spare the time and energy of opening up each file and comparing it with the rest after they have been detected as suspected duplicates because of matching filenames.
And by the way, just to ensure there is an increased degree of objectivity and you do not mistakenly delete a file, we recommend you perform a second ‘step’ before making the final call on if 2 (or even more) files are duplicates or not. If you’ve detected some files to be named the same way, you can compare their file size. If the files’ size is different, they simply aren’t duplicated and you can safely ignore them. But if the file size also matches bit by bit, this is most probably a case of duplicates and you should carefully review all the suspect files.
This was a neat little tip to further refine the suspected duplicate DMG files into a subset. Now we will briefly describe another downside of the manual method before we move on to the automated solution of finding and deleting duplicate DMG files on your MacBook.
By now you must have determined all the manual methods depend on the user to compare the files and judge if some/ all of them are duplicated or not. This might go well in the beginning, but can a user ensure they continue to examine files at their best even after they’ve performed this job for a good while? It is most definitely a long shot by all means.
Let’s take a quick look at the manual way of how you can search for duplicate DMG files on your MacBook.
Let’s switch to the automated method now. This is a software program that scans and deletes DMG files with unparalleled accuracy. Since this is a software program, it is extremely swift in accomplishing the entire scan, detect and deletion process.
The software program is named Clone Files Checker, and it does what its name suggests. It will run a comprehensive scan in the target scan location and list out all the duplicates in a neatly presented layout within minutes. The duplicates are divided into categories such as Documents, Archives, Music, Videos, Images etc so the user can easily view the results of a specific file type.
This software does wonders in digging out DMG files on your MacBook’s SSD. It is super-accurate in accomplishing the task, super-light in occupying your Mac’s resources, and super-fast in completing it all. This is a complete package and delivers results par excellence.
Now we get to the biggest one. This software simply does not take into account the filename, file type, file size etc while comparing files for duplication. It minutely scans the file’s content bit-by-bit rather than giving any weightage to the file tags. This intelligent usage of smart algorithms means there is no chance of an error at any stage during the entire process.
Here is how it unfolds:
The best part about Clone Files Checker for Mac is that the user is in control of the entire process at every single stage, without them being overburdened. This is a very smart way of scanning and deleting multiple copies of DMG files from your MacBook SSD with great speed.
