如何缩小/调整apfs的大小？

Question

我想缩小引导文件系统的大小(格式化为APFS)，怎么做呢？

在macOS Sierra中，HFS+可以在不重新启动/重装的情况下缩小(在disk utility中)，但是在macOS High中，这似乎是不可能的。

您要查找的命令是diskutil apfs resizeContainer。

Usage:  diskutil APFS resizeContainer <inputDisk> <newSize> [<triple>*]
        where <inputDisk> = A Container Reference DiskIdentifier (preferred)
              or a Physical Store DiskIdentifier
              <newSize> = the desired new Container or Physical Store size
              <triple> = a { fileSystemPersonality, name, size } tuple
Resize an APFS Container. One of the Container's Physical Store disks will be
resized, and therefore its Container will be resized by an equal amount. You
can specify a new size of zero to request an automatic grow-to-fit operation.
If the new size implies a shrink, you can specify ordered triples in the same
manner as diskutil partitionDisk, etc, to fill the partition map's free space
gap that would otherwise result. If there is more than one Physical Store and
you specify a Container Reference, the appropriate Physical Store will be
chosen automatically. Ownership of the affected disks is required.
Example:  diskutil apfs resizeContainer disk5 110g
          diskutil apfs resizeContainer disk5 110g jhfs+ foo 10g ms-dos BAR r
          diskutil apfs resizeContainer disk0s2 90g jhfs+ foo 10g ms-dos BAR r
