See my old post here on this same issue and how to delete the cache files.

Aside from this large folder, I don't see any others that look off from normal. Assuming the Users space is in line with what you have in personal data on there.
Thanks, is there no way of finding this file/folder without using a terminal command? I have installed xcode, I think I'll uninstall it as never use it.

If I delete the whole cache folder would this effect all apps/software in a negative way?

You can see it, but not delete it from Finder since it is a protected system folder. You will need to delete from the command line in single user mode like I described.

Deleting the entire cache folder won't hurt a thing. When you restart afterwards the system will recreate all the needed cache files. That first start after a cache delete just takes an extra couple seconds since it has to recreate the cache, but no biggie.

Thanks. Yeah I just found the folder and found I couldn't delete it :oops:

Ok so I've just pressed CMD-s on start up and now it's hung on this screen :( How do I get past this?

 
OK so I typed exit and hit enter and it booted up, but I don't think it's in single user mode as it gave me the option to choose users at login.
 
OK so I guess it was in single user as I typed in the command, restarted the mac and now I have 282GB free on the hard drive. Thanks so much for your help. There's still circa 40GB unaccounted for, but I'm sure that will be OS and system files. Really appreciate the help guys.

Looks like you are in good shape there. :)

This should not be this hard for users to do in MAC OS, and users should not have to use terminal. What typical user is going to know what folders are good to delete. Apple still continues to hide so much ...

I recommend you buy a program to scan for and clean up all the system crap that accumulates. Cleanmymac 3 or something similar.

Apple isn't trying to hide things, sometimes you need to do stuff in single user mode so that the files are not in use by the running operating system.

But without the help on here I would have never found the 'missing' storage.
