I have no idea why but I have tons of files on the system. I tried to use third-party apps to delete unnecessary files from the system but it didnt change anything. I already searched on google but I found nothing to solve this problem. Any idea?
Hmm. Right. Figured it was local time machine backups. Guess not. The commands I listed flush the local backup cache without touching the actual backups.
I have seen this with Disk Wave....I like it but don't think it is getting updated. I just tried it the other day (on a Mac running 10.13) and it was similar to what you got.
Too bad. I nice tool with an easy interface.
Disk Sweeper is up to date and works well, tested through 10.13. Just ran it to replace Disk Wave. Worked great.

One other tip, at least for Disk Sweeper. Occasionally, running it as an admin user does not show everything.....and the numbers don't add up.
If that happens you can run it as the root user......and it will see everything.
I probably only need to do this about 1 out of 20-30 times I use it. Run it from your regular admin account first, but if you need to you can run launch it as root from the Terminal.
