Program to find duplicate files

There’s hardly an IT-guy today who doesn’t deal with APIs in some way. And Postman is exactly the tool that pulls product, dev, or QA into one place to design, test, and debug APIs faster, contributing to developer time savings of up to 75% in API design.

But if you’ve moved your workflow elsewhere, want to reclaim storage space, or don’t use Postman as often, you might be ready to uninstall it. And as with most dev tools, it’s not just about dragging the app to the Trash, you’ll want to make sure to properly handle your workspaces, collections, synced data, and CLI components.

In this guide, you’ll learn how to completely uninstall Postman on a Mac, manually and automatically, how to reset the app, clean its cache, back up your API collections, delete a workspace, Postman account, and even Postman CLI if you’ve installed it.

Uninstall Mac apps like a pro

Don’t waste time chasing files, sorting through folders in your attempts to delete an app. App Cleaner & Uninstaller does this tough job for you. It is a professional tool that finds every Postman residual and deletes it with precision. Seconds in this tool, a few clicks, and your Mac is light and organized.

Two ways to uninstall Postman on Mac

I tested Postman v11.68.0 on my Mac Pro M3 (26.0 Tahoe) to compare both approaches: the traditional manual removal and the automated cleanup with App Cleaner & Uninstaller.

Method Difficulty Time Pros Cons Best for
Manual (Finder) Medium ~12 min Free; full control Risk of missing hidden files; more steps Experienced users comfortable with Finder and Library folders
App Cleaner & Uninstaller Easy < 30 sec Quick; automatically removes all leftovers Requires downloading an extra tool Those wanting a one-click complete cleanup

How to uninstall Postman manually

Step 1. Quit Postman and stop background processes

  1. Open Activity Monitor.
  2. Type Postman in the search bar.
  3. Select all Postman-related processes → click the ✕ button → Force Quit.

Step 2. Delete the Postman app

  1. Open Finder.
  2. In the left sidebar, select Applications.
  3. Find Postman.app → right-click → Move to Trash.

Step 3. Remove Postman leftovers from Library

Even after deleting the app, Postman leaves multiple support files. To remove them:

  1. In Finder, click Go → Go to Folder.
  2. Type 
    ~/Library/

    Copy

    and press Return.
  3. In the search bar, type Postman.
  4. Open Name Contains.
  5. Double-check you search within the Library, not This Mac.
  6. Select all Postman-related files → right-click → Move to Trash.

I found the following directories that contain Postman data:

  • ~/Postman

    Copy

  • ~/Library/Application Support/Postman

    Copy

  • ~/Library/Application Support/com.apple.sharedfilelist/com.apple.LSSharedFileList.ApplicationRecentDocuments/com.postmanlabs.mac.sfl4

    Copy

  • ~/Library/HTTPStorages/com.postmanlabs.mac

    Copy

  • ~/Library/Preferences/com.postmanlabs.mac.plist

    Copy

There were also files starting with com.postmanlabs.mac in these folders:

  • ~/Library/Caches/

    Copy

  • /private/var/folders/***/***/***/

    Copy

    *** denotes temporary folder names that differ per user. To quickly locate them:

    1. Open Finder → press Shift + Cmd + G → go to /private/var/folders.
    2. Type com.postmanlabs in the search box.
    3. Double-check the result is for /private/var/folders/ path.
    4. Delete all results related to Postman.

Depending on the way you used Postman, checking two more paths wouldn’t hurt:

  • ~/Library/Logs

    Copy

  • ~/Library/Launch Agents

    Copy

Alternative tip

If you’re unsure whether everything’s gone, use Funter by Nektony – a free tool that reveals hidden files. What’s more, you can delete them from this tool. To that end:

  1. Download for free and launch Funter.
  2. Type Postman in the search field.
  3. Review, select, and delete all Postman-related files.

Step 4. Empty the Trash and restart

Once you’ve removed all related files, empty your Trash and restart your Mac.

How to remove Postman automatically

If manual deletion feels like too much effort, App Cleaner & Uninstaller does the same job automatically and faster. It finds all hidden files in a matter of seconds. Here is the flow:

  1. Download App Cleaner & Uninstaller → open it.
  2. Look up Postman among the Applications.
  3. Select it → click Uninstall.
  4. Confirm the removal of Postman and all associated files.

That’s the way. Easy as I said. The good news is, this tool has a free trial for two days.

Plus, if you already dragged Postman into the Trash earlier, App Cleaner & Uninstaller is a helper here, too. Just open the Remaining Files tab. It’ll detect all leftovers of Postman and all other apps you can safely remove in one click.

How to delete Postman cache and reset it

  2. Search for Postman → select it.
  3. Turn on Expert Mode.
  4. Choose Caches in the right sidebar → click Remove → confirm.

Resetting Postman restores it to its default state without uninstalling it completely.
