I ran in to a problem with a new Western Digital hard drive (2TB) for use as a Time Machine backup drive on High Sierra. After plugging it in, I kept getting errors like "MediaKit reports not enough space on device for requested operation." After some digging, it appeared that this is an issue in macOS with initializing APFS from an NTFS partition.
Pulling out some old utils, I used diskutil
and dd
to fix the issue:
$ disktuil list
...
/dev/disk4 (external, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *2.0 TB disk4
