So I keep getting the above error at the following step,

  1. Downloading windows support software - OK
  2. Partitioning disk - OK
  3. Copying windows files - OK
  4. Saving windows support software - ERROR

I have tons of free space on my SSD (MBP mid-2015) and I'm allocating 140GB for Bootcamp partition.

Below is the output of diskutil list,

roberts-mbp:~ robertdunbar$ diskutil list
/dev/disk0 (internal, physical):
   #:                       TYPE NAME                    SIZE       IDENTIFIER

   4:                APFS Volume VM                      1.1 GB     disk1s4

The output of fsck_apfs -s -o -y /dev/rdisk1 is as follows,

roberts-mbp:~ robertdunbar$ sudo fsck_apfs -n -l /dev/rdisk1

Help appreciated.

  • The Boot Camp Assistant creates a temporary partition (OSXRESERVED) and copies the files to this partition. I suppose one could execute the diskutil list command while the Boot Camp Assistant is coping the Windows files. This would get the size of this partition. You could also just download the Windows Support Software to get the size. Finally, you could mount the Windows ISO file and determine the size of the files. Do the math and see if there is a space issue. – David Anderson Apr 6 at 13:55
  • Did the error message say the following? Your bootable USB drive could not be created There is not enough space available on the disk. – David Anderson Apr 8 at 3:35
  • Problem solved. There is a bug with the October Windows 10 ISO and BCA in the latest version of Mojave (10.14.4). The April Windows 10 ISO installs correctly. Thanks. – Robert Dunbar Apr 8 at 9:10
