After upgrading to macOS 10.13 High Sierra, you may notice that there is a category named "Other Volumes in Container" in Storage and "Other Volume" in Disk Utility on your Mac. The problem is that when you get the warning "your disk is almost full" from the Mac, other volumes in container has already taken ten or even hundred gigabytes of your Mac storage space. Some users also notice that the size of other volumes in container keeps growing on their Macs, but they don't even know what other volumes in container means, let alone how to delete other volumes in container.

So, in this post, we are going to explain to you what other volumes in container is on Mac and how to get rid of other volumes to reclaim your Mac storage.

Other Volumes in Container Mac

1. What is Other Volumes in Container on Mac?

In APFS, the new file system that Apple introduced to macOS High Sierra and later, a container is similar to a partition in other file systems. A physical disk could have multiple containers and a container includes multiple virtual volumes, which all share the storage space of the container. For example, a standard macOS startup APFS container includes volumes as follow:

Macintosh HD: the volume with macOS software system installed, which usually shown in Disk Utility as Macintosh HD.

Preboot: the volume that manages boot, which is created during macOS High Sierra update to support booting to Macintosh HD. It is usually hidden.

Recovery: the volume that contains recovery system of your Mac, which you can boot into by holding CMD + R during startup.

VM (Virtual Machine) : the volume that supplements your RAM to store files like sleepimage, swapfile, which is too large for RAM to run. So VM volume usually takes up most of the storage space.

Other volumes in container means the last three volumes: Preboot, Recovery, VM in APFS container. Other volumes cannot be removed because they are needed for macOS to function properly.

Can We Delete Other Volume in Container?

Although we know what other volumes in container is, it doesn't mean that we can easily get rid of other volumes in container. In fact, we cannot completely delete other volumes in container on Mac because it is important for the system to run. However, there are still some ways to stop other volumes from expanding or reduce the space that other volumes currently used.

2. How to Remove Other Volumes in Container in Storage

There are 7 fixes shared by Mac users who have successfully regained storage space from other volumes in container. Hopefully one of them may work on your case.

Method 4 Uninstall Suspicious Third-party Apps

We may unconsciously download third-party apps on the internet by entering a malign web page or clicking the wrong button. These apps take up a certain part of Mac storage and lead to the problem “your disk is almost full”.

You can go to Application > Utilities > Activity Monitor and check on the Memory tab. If there is any process that is using extraordinarily huge space of your Mac storage, the app that is running the process could be the culprit.

Check Activity Monitor

So, kill the process and then check if other volumes in container is still taking up lots of space. If other volumes give back your space, then go on and completely uninstall the app.

By completely uninstalling an app, it doesn't mean simply dragging the app to Trash. You need to delete the app as well as its data.

Method 5 Remove Extra APFS Volume

If you have read the methods above and still don’t know what to do, it is recommended to have a clear picture of what volumes your drive consists first. We can run this Terminal command: diskutil list.

After the window pops up, check if there are more than one Macintosh HD - Data volumes. If there is an extra Macintosh HD volume, it is very likely that the extra one has been eating out your space.

To delete this volume, follow the instructions below.

1. Open Applications > Utilities > Disk Utility on Mac.

Disk Utility Mac
