Hi, I want a space to install Linux on my MacBook Pro. For this, I am trying to resize one of my APFS partition. However, I am failing. Whenever I am performing a partition shrink using Disk Utility, an error code 49153 prevented me from accessing the APFS container. But I really need the working files on one APFS volume. Can anyone tell me how to recover lost data after resizing APFS container?

As a drive can have multiple containers, users may wish to resize APFS container to optimize their file storage. But some unexpected quirks happen after resizing APFS container, such as the above APFS resizing error, which will result in data loss problem. If you are facing data loss problem after changing APFS container size, just read ahead to get effective solutions.
