How to Delete APFS Partition/Volume on Mac without Data Loss?

APFS, short for Apple File System, is a new file storage system for macOS, iOS, watchOS, tvOS, and Apple devices.  When you upgrade your system to macOS 10.13 High Sierra and later versions, the system drive will be automatically converted from HFS+ to APFS.

I got a "Your disk is almost full" message. My MacBook became very slow. When checking storage, "Other volumes in container" was taking up to 30GB, but it constantly changed. Sometimes it took a gig or two, and other times 30GB. I'm running a High Sierra 10.13. How to delete this APFS partition? Any suggestions will be appreciated!

Similar to the example above, lots of Mac users have noticed some weird stuff called "Other Volumes in Container" in Disk Utility. It's impossible to ignore them as these volumes always take hundreds of gigabytes of your Mac hard drive space and their size keeps growing. 

In this case, you may wonder what is other volumes in the container and how to get rid of them on Mac to free up space on Macintosh HD. No matter what the reason you decide to delete an APFS partition, just follow the step-by-step tutorial.

What happens if I delete APFS volume?

When deleting a partition on a Mac, all data stored on the partition will be erased and the partition will be removed (erasing APFS only clears the contents but remains the partition). Therefore, before you proceed, please make sure you have made a complete backup of your important data. 

You can manually take a backup of your files on any external drive. Alternatively, you can also turn on Time Machine, and take advantage of iCloud or Google Drive. The easiest and fastest way to create a backup of the volume/drive is using a third-party cloner for Mac, such as iBoysoft DiskGeeker for Mac.

iBoysoft DiskGeeker for Mac is an all-in-one disk management tool for Mac, the Disk Clone feature enables you to make a 1-to-1 copy of the target disk. In addition to the startup disk, it also supports cloning an external hard drive. After cloning the disk, you don't need to worry about data loss when deleting the APFS volume.

How to delete an APFS volume?

Please note that under APFS, there is a new concept: container. A Container is the basic storage unit for APFS. Every APFS container contains one or more volumes.

First of all, you should make it clear which one you want to delete.
