Question

Not enough disk space to complete the migration - Mac OS

When migrating the catalog I always g t he error, I even moved all my original photos out to an external drive before beginning.

I think this is q problem in Mac OS - High Sierra.   Adobe Lightroom CC expects 174 GB of free space.

The hard disk  indicates 336 GB free.  However Mac OS also has  222 GB eraseable space .  I think Adobe only recognizes this net of 114 GB totally free space not the disk available space.   Bug maybe ?

Any advice on this ? Lightroom CC​@

This is probably due to APFS keeping "purgeable storage" around, and a bug in LR where it fails to access this perfectly usable space.

To hack around this, you can go into Terminal and do the following.

$ df -h #shows 32G free
Filesystem      Size   Used  Avail Capacity iused               ifree %iused  Mounted on
/dev/disk1s1   932Gi  896Gi   32Gi    97%  812940 9223372036853962867    0%   /
# this step takes a while -- monitor your disk space
$ dd if=/dev/zero of=zeros bs=9000 #and then hit CTRL-C once your disk is completely full
^C17539950+0 records in
17539949+0 records out
350798980000 bytes transferred in 554.492292 secs (632648974 bytes/sec)
$ rm zeros #delete the large temp file
$ df -h #shows 328G free
Filesystem      Size   Used  Avail Capacity iused               ifree %iused  Mounted on

Then retry your import. This worked for me.

I moved all photo's to an external drive with plenty of space and that works as no 'erase-able space'.
Question now is how do I get the data back to my MBP folders@?
