I tried to move a folder from an external drive to my new MacBook Pro's internal drive, but get a "Not enough disk space" error:
The folder I'm moving is 23.89 GB:
But my internal drive is supposed to have 54.71 GB available (and also 40 GB purgable on top of that):
EDIT: Or am I misreading those numbers? Is it actually 54.71 available whereof 40 are purgeable? That would make more sense since 499.96 capacity - 480.35 used = 19.61, which is far from 54.71. But then, 19.61 does not exactly match 14.71 (54.71 available - 40 purgeable) either.
What's going on here?
I should add (because I suspect it may be a factor) that I'm in the progress of uploading a big iPhoto library from my internal drive to iCloud. I just paused that upload for the day. Could it be that it somehow reserves some disk space?
Or might it simply be a matter of Finder misreporting available space, since those numbers don't add up per my edit?
I'm on Mojave (10.14.5).
