Alright, so, I cleaned up my disk. Finder shows 63 GB free. "Storage" tab in "About This Mac" shows the same...
However, using QuickLook on my disk (one and only disk I got with computer) shows 17 GB free only?!?
df -h
also shows really strange output:
Filesystem Size Used Avail Capacity iused ifree %iused Mounted on
/dev/disk1s1 113Gi 97Gi 13Gi 89% 1427126 9223372036853348681 0% /

map -hosts 0Bi 0Bi 0Bi 100% 0 0 100% /net
map auto_home 0Bi 0Bi 0Bi 100% 0 0 100% /home
I am not using and never used Time Machine backups on this computer, there are no "purple bands" in "Storage" window, I tried to reindex the volume (by adding and removing a folder in Spotlight settings), my trash is completely empty, I tried to reboot couple of times...
Why is this happening??
