75 Gb so I'd go right ahead and remove some of it.ĭon't worry about age, I'd worry about size.
On the three machines I just checked none had a /Library/Caches folder over. If the cache /Library/Caches folder is over 3Gb then you have something that is caching quite a lot. This folder can run quite large just because so many apps cache something in there. If you have a look in ~/Library/Caches you will find a bunch of applications have a cache in there, none of them particularly large though dropbox sometimes has a fair sized cache. The caches in /System/Library/Caches are generally small and useful, the ones in /Library/Caches are less system caches and much more readily cleared. It's generally safe, though a little dangerous depending, to do it but often not worth the effort.
