mac disk image incorrect free space zero

I was worried it was an issue with the new APFS file system introduced to all SSD-using Macs as of High Sierra, but in this case it turns out the issue is that Time Machine retains local snapshots on disk, in addition to the full backup history that is retained on the network time machine device.Īpple state that they automatically remove local snapshots when disk space is low, but their definition of low is apparently only 5GB of free space remaining – not really much free working space in 2017 when you might want scratch space of 22GB for 1 hour of 4k 30FPS footage. I've googled it and the Apple forums seem useless as usual, I've tried deleting local snapshots from Time Machine using terminal. I just deleted about 200gb of files from my desktop, and there is no change in free space. After migrating a considerable amount of undesirable data to either the file server or /dev/null, I found that despite my efforts, the amount of free disk space had not increased. I only have a few hundred GB of my own files.

I recently ran out of disk space on my iMac.
