Apple: What is com.apple.coresymbolicationd in caches? (6 Solutions!!)
It is used for debugging and analyzing crash reports. /System/Library/Caches/com. apple. coresymbolicationd/data was also about 600 MB on my account, so I guess it’s normal. Deleting files in cache folders is generally safe, and /System/Library/Caches/ is even excluded from Time Machine backups.
