Some 30 Gb of space wasted in /System/Library/Caches

[davydden]

Hi all,

after some calculations i got about 20 (maybe more) Gb dissapeared on my harddrive. Repairing hard drive, permission, restarts - does not help.

My best guess is that some swap file was not cleared, or was damaged or whatever.
When I check disk space i got:

$ sudo du -d 1 -x -c -g /

/System being 37 Gb is bit to much. A colleage of mine has 7, in a similar issue here the author had 8.
Looking at /System i see Caches taking 33 Gb (!!!) of spaces:

if I dig deeper, i see

$ sudo du -d 1 -x -c -g /System/Library/Caches/
Password:
33    /System/Library/Caches//com.apple.coresymbolicationd
1    /System/Library/Caches//com.apple.CVMS
1    /System/Library/Caches//com.apple.kext.caches
33    /System/Library/Caches/
33    total

so the question is how can I clean up `com.apple.coresymbolicationd`?
I can see the size breakdown of the content, even with `sudo`...

**UPDATE**

i ended up restarting in the safe mode (CMD+S), then doing `sudo mv /System/Library/Caches/com.apple.coresymbolicationd /tmp` and then restarting again.
On restart the temporary folder got cleaned up.
