I wish to install Linux and shrink my existing volumes + add a new partition with 600 GB for Linux.

diskutil list
/dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *2.0 TB     disk0
   1:                        EFI EFI                     314.6 MB   disk0s1
   2:                 Apple_APFS Container disk1         2.0 TB     disk0s2

/dev/disk1 (synthesized):
   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      APFS Container Scheme -                      +2.0 TB     disk1
                                 Physical Store disk0s2
   1:                APFS Volume Macintosh HD            15.3 GB    disk1s1
   2:              APFS Snapshot com.apple.os.update-... 15.3 GB    disk1s1s1
   3:                APFS Volume Macintosh HD - Data     1.1 TB     disk1s2
   4:                APFS Volume Preboot                 520.9 MB   disk1s3
   5:                APFS Volume Recovery                622.1 MB   disk1s4
   6:                APFS Volume VM                      2.1 GB     disk1s5

The UI (Disk Utility) does not allow me to create more than 36 GB partition. I can't fill out the number.

free disk space not the issue:

current setup in UI:

not allowed to enter custom number bigger than 36 GB.

    The free space isn't continuous, most likely. May 22, 2021 at 15:51
  • The entire disk is taken up by the APFS container. To do what you want, it would have to shrink the APFS container. Apparently that's not possible, I couldn't say why for sure. Aside... why do you want to install a pseudo-Linux to replace a real one? Do a VM. May 22, 2021 at 16:18
