Available Bug

[anpaman]

Hi all

I was using MacBook Pro 2017 nTB with 256 ssd and High Sierra 10.13.4

Today I found something weird with the disk available in this OS.

Example ssd has 12 GB available and I have copy single 2 GB file from download folder to desktop or other folder and after copied the available still 12 GB. I was using copy and not cut and paste.

It was normal when I copy file from external hdd or flash disk to Macbook Pro. The disk available will reduced.

Is it High Sierra bug ?

Thank

I think what you are seeing is a function of the way the APFS file system makes copies without using double the data, and is normal. You can read about it at this link.
