Every so often you need to tidy up, and that goes for your devices as well as your closets and drawers. But a digital cleanup can turn out to be trickier than sorting through a messy closet \u2014 especially on macOS.<\/p>\n

Getting rid of old photos and files is straightforward enough, but fully removing an app from macOS is another story. You\u2019d think dragging an unwanted app to the Trash would do the job, but in practice, that app can leave behind settings files, cache, logs, helper files, and other related junk. Over time, all these leftovers pile up and eat away at your storage.<\/p>\n

To make this kind of cleanup easier, Kaspersky for macOS<\/a>\u00a0now includes a feature called App Cleaner<\/a>. It removes apps along with all their related files, and it can also track down the remains of apps you deleted earlier. This post explains where these leftover files come from, shows you how to use App Cleaner, and explains why installing the first Mac cleanup tool you find online isn\u2019t a great idea.<\/p>\n

Why deleted apps leave traces on your Mac<\/h2>\n

As Apple products go, macOS works in some unusual ways. Every longtime user runs into its quirks sooner or later, though that doesn\u2019t stop us from loving it with all our hearts. Apps are no exception: the way macOS handles them is more complicated than it looks.<\/p>\n

Most people picture an app on macOS as one specific item. Take Photoshop: it\u2019s that familiar icon with the letters Ps<\/strong>, sitting in the Applications folder in Finder, ready to launch with a click. But under the hood it\u2019s more complex. What looks like a single item in Finder is actually an app bundle<\/a>: a folder containing the program itself along with everything it needs to run.<\/p>\n

But even that is only part of the picture. While Photoshop is running, like any app, it creates and uses data stored outside that bundle. Some of this is behind-the-scenes data, like cache, settings, and user documents. Some of it is your own work, like PSD files. The distinction matters: if you delete Photoshop, you don\u2019t expect your PSD files to vanish along with it.<\/p>\n

Then there\u2019s how Adobe doesn\u2019t just install Photoshop or Acrobat: it also deploys a whole set of common apps and background services alongside them. Dragging the Ps<\/strong> icon to the Trash won\u2019t remove those, and neither will Adobe\u2019s own uninstaller.<\/p>\n

These background files and helper services can stick around on your drive after you\u2019ve deleted the app they came from. Worse, if you use Migration Assistant<\/em> to move to a new Mac, all that dead weight gets copied over automatically. So it\u2019s entirely possible to have never installed a single Adobe or Microsoft app on your current Mac, yet still be carrying around megabytes, or even gigabytes, of useless files tied to them.<\/p>\n

Tracking these files down yourself isn\u2019t easy, primarily because most people don\u2019t even know they exist. Even if you suspect something\u2019s hiding on your drive, you probably won\u2019t know where to look or what the files are called. To make things harder, file names rarely give away which app they belong to.<\/p>\n

\"App<\/a>

The new App Cleaner feature helps you remove apps along with the files they leave behind<\/p><\/div>\n

Most of these background files live in special macOS folders. One of the main ones is Library, which contains folders like Application Support (app data) and Caches (temporary files). But Library isn\u2019t easy to get to. Since OS X 10.7, Finder keeps it hidden by default<\/a>. To find it, open the Go<\/em> menu in Finder while holding down the Option<\/em> key. Only then does Library show up.<\/p>\n

Even if you\u2019re determined enough to dig through Library, you\u2019ll still have to figure out for yourself which of the many files belong to which apps, and which ones are safe to delete. Fortunately, you don\u2019t have to do this by hand, because that\u2019s exactly what App Cleaner<\/a> takes care of.<\/p>\n

How App Cleaner finds and removes apps without leaving traces<\/h2>\n

App Cleaner doesn\u2019t just remove the app itself. It also tracks down every file connected to it. It does this by automatically identifying which files belong to which app, mainly using the app\u2019s unique identifier (bundle ID<\/a>) and typical file locations. This means it can clear out an app\u2019s leftovers even when they\u2019re scattered across different macOS folders.<\/p>\n

Keep in mind that a full cleanup like this also removes the app\u2019s saved data, so you\u2019ll need to set things up again\u00a0\u2014 for example, restore browser extensions\u00a0\u2014 if you reinstall it later; you can also lose game save files. That said, App Cleaner never touches your own files. Delete Photoshop with it, and the leftover files disappear while your PSD files stay exactly where they are.<\/p>\n

You can\u2019t remove the extra files separately from the app itself. App Cleaner offers to delete them together as one package. But if you\u2019ve already deleted an app the regular way and its data has stuck around, App Cleaner can find and remove that too.<\/p>\n

If you accidentally delete something you needed, don\u2019t worry. App Cleaner<\/a>\u00a0moves everything to the Trash first rather than deleting it outright. As long as the Trash isn\u2019t emptied, you can restore those files from there, and if you haven\u2019t closed App Cleaner since deleting them, you can restore them directly from the app instead. Files only disappear for good once you empty the Trash. We\u2019ll walk through how to undo an accidental deletion below.<\/p>\n

How to remove an app with Kaspersky App Cleaner: a step-by-step guide<\/h2>\n

Now let\u2019s put this into practice. To use App Cleaner, open Kaspersky for macOS<\/a>\u00a0and head to the App Cleaner<\/em> section. You\u2019ll find it right on the app\u2019s main screen, in its own App Cleaner<\/em> block, or under Performance<\/em> in the left-hand menu.<\/p>\n

\"Where<\/a>

You can open App Cleaner from the main screen of Kaspersky for macOS, or through the Performance section in the left menu<\/p><\/div>\n

In the Apps<\/em> tab, you can see every app installed on your Mac. Select the apps you no longer need, click Remove<\/em>, then confirm your choice to delete them along with all their related files. The deleted files move to the Trash, from where you can restore them if needed. Ready to say goodbye for good? Just empty the Trash.<\/p>\n

Before you remove anything, App Cleaner shows you not just the app but every file tied to it that will be deleted along with it, plus how much space each one takes up and where it\u2019s stored. That way, you know exactly what you\u2019re clearing out before you commit.<\/p>\n

\"How<\/a>

Select the app you want to remove in the Apps tab and click Remove. App Cleaner will delete it along with its related files<\/p><\/div>\n

App Cleaner can also find leftovers from apps you previously deleted the regular way (by dragging them to the Trash). These show up in a separate Leftovers<\/em> tab, where you can see what\u2019s left, how much space it takes up, and where it\u2019s stored. To clear them out, click Remove<\/em>, then confirm by clicking Delete<\/em>. As always, you can restore these files from the Trash if you change your mind.<\/p>\n

\"How<\/a>

The Leftovers tab collects files left behind by the apps you\u2019ve already deleted. Select the ones you don\u2019t need and click Remove<\/p><\/div>\n

Before closing Kaspersky for macOS and emptying the Trash, double-check that you haven\u2019t accidentally deleted a piece of software you need. If you have, you can bring back an app along with all its files right from App Cleaner: select the deleted app from the list and click Restore All<\/em>. Once you close Kaspersky for macOS<\/a>, you can still recover deleted files from the Trash as long as you don\u2019t empty it yet.<\/p>\n

\"How<\/a>

Select the deleted app and click Restore All. App Cleaner will bring it back along with its related files<\/p><\/div>\n

Leftover files work the same way. As long as Kaspersky for macOS<\/a> is still open, you can restore them through App Cleaner. Once it\u2019s closed, the Trash is your fallback.<\/p>\n

Once your drive is free of clutter, it\u2019s worth checking on its overall health too. That\u2019s where another Kaspersky for macOS<\/a>\u00a0feature \u2014 Hard Disk Health Monitor<\/a> \u2014 comes in handy.<\/p>\n

Not every cleanup tool is safe<\/h2>\n

When it comes to tidying up a Mac, it\u2019s tempting to just download the first app that promises to clear out junk and free up space. But you should be careful about which program you choose. Criminals often disguise malware as well-known, legitimate Mac cleanup utilities. Kaspersky researchers have already found fake versions posing as CleanMyMac, Mole, and CCleaner Pro.<\/p>\n

With Kaspersky, you don\u2019t need to look for a separate cleanup tool at all. App Cleaner is already built into Kaspersky for macOS<\/a>. That means one solution protects your device from cyberthreats and clears out unwanted app leftovers \u2014 without the risk of accidentally downloading harmful software disguised as a cleanup tool.<\/p>\n

What else is new in Kaspersky for macOS<\/h2>\n

App Cleaner helps you tidy up your Mac quickly and safely, freeing up time you can spend sorting through your own files instead \u2014 something no app can do for you yet. To get access to App Cleaner and other advanced protection features, purchase Kaspersky Premium for macOS<\/a> or sign up for a free trial<\/a>.<\/p>\n

That\u2019s not the only new feature in Kaspersky for macOS. The app now includes Scam Protection Hub, a single control center for AI-powered protection against digital fraud. There\u2019s also Shop with Confidence, which is now available across all our home security products<\/a>. Alongside our longstanding filters for malicious sites, this feature blocks links to gray-area sites<\/a>, like online stores that copy well-known brands to sell fake goods.<\/p>\n

Still think macOS is immune to threats? Think again. Our research has found that Mac users actually run into cyberthreats more often than Windows users<\/a>! Curious what those threats look like? Check out our other posts:<\/p>\n
