I knew that one fine day I would face a lack of free space on my Mac computer. So, today I skimmed and analyzed my installed applications to see which of them is useless for me. The Docker for macOS occupies 1.2 GB and I don’t use it anymore. So it’s time to stop Docker from taking up useless disk space. If, for your own reasons, you also need to get rid of this app, follow this guide on how to fully and correctly uninstall Docker on Mac.
Remove Docker Manually
Open the Applications folder in Finder → scroll and select Docker → make a right click → in the context menu select Move to Trash.
But this is not the complete removal of Docker from Mac. Actually, every application creates support files on a computer so that all functions work properly. Somehow these files penetrate deeply into the system folders. That’s why simple moving the Docker application into Trash is not enough for a total deletion from the computer.
Application support files are usually stored in the Library folder. As this system Library folder keeps important data, by default it is hidden from users.
- To open the Library folder, you have to open the Finder window and in a Menu Bar click on Go Go to Folder.
- In the search field that appears, type ~/Library and click Go.
- Now you have access to the Library folder. Find there the Application Scripts folder, scroll and select the “com.docker.helper” folder, make a right click and move it to Trash.
- Then check the Caches folder and delete the “com.docker.docker” folder from there.
- Finally, to clean up all remains, that were created by Docker, delete all containers as well. Open the Containers folder in the Library folder, find “com.docker.docker” as well as “com.docker.helper,” and delete them.
Uninstall Docker Easily
Fortunately, a friend of mine advised me about an app, which removes applications with all its remains automatically. The program is called App Cleaner & Uninstaller. It’s free of charge and available for everyone to download from the App Store. Here then is the second way to uninstall Docker for Mac:
- Launch App Cleaner & Uninstaller.
- Select Docker from the list of applications. All system files and folders related to this app will also be selected. Click the Remove button.
- In the confirmation window, preview the files and confirm removal by clicking the Remove button.
- Empty the Trash for complete removal of Docker from your Mac.
What’s interesting is that App Cleaner & Uninstaller shows that Docker occupies 3.65 GB, while the executable file is only 1.20 GB. This means that I had gigabytes of service files related to Docker. So, in fact, the remains of the app take up more space on your disk! It is therefore important to find and remove them when you need to uninstall Docker and clean up your Mac.
This tool uninstalls applications from Mac completely and safely in less than in a minute. Download it once, and you will forget about seeking out unnecessary files on your computer or wasting so much time uninstalling apps manually.
