Look how huge is the system storage:
Is anyone having the same problem than me? I do not konw why this is happening.
MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13), 13", 1TB SSD, 16GB RAM, 3,3 GHz
I went to Launchpad then "Other", then to "Terminal". When that opens, you'll see a prompt after your user name. Then type this:
sudo tmutil listlocalsnapshots /
Be sure to include the spaces and the "/" at the end.
It will ask for your password which is the same password you use to unlock your Mac.
Then it will list the snapshots you have on your system. The rest is explained in JamBeats post from earlier in this thread. I'll paste it here:

Turned to our good friend Google and I found that Time Machine local backups were the reason and 'sudo tmutil disablelocal' command was supposed to help, if only "disablelocal" verb had not been removed from High Sierra. So back to square one.
Did some digging a.k.a. opened the manual for tmutil. I found that there were two useful verbs "listlocalsnapshots" and "deletelocalsnapshots". Used the first one to get the exact date stamps required for the second one and deleted all local snapshots manually.
Result: "System" went from 158GB to 20GB.
Step by step I went as following:
Code:sudo tmutil listlocalsnapshots /
This resulted:
Code:com.apple.TimeMachine.2017-09-27-005259
com.apple.TimeMachine.2017-09-27-104645
com.apple.TimeMachine.2017-09-27-114218
com.apple.TimeMachine.2017-09-27-124220
I took these four date stamps and followed the next command with each as following:
Code:tmutil deletelocalsnapshots 2017-09-27-005259
So in the end if i double checked with
Code:sudo tmutil listlocalsnapshots /
there were no snapshots and after checking "About This Mac -> Storage" I was overjoyed!
Hope this helps!

I had about 8 snapshots in my original listing. After doing this procedure, my system storage size went from over 1.2TB to just over 20gb.
Hope that helps! Thanks again to JamBeats for posting the process.
My "system" takes up a whoping 755 GB storage, but when i did this terminal thing, no backups even showed up.
Nice tip, thanks.
What does the 686Gb / mean on the terminal window seconds to last line? Does it mean available storage?
I had this problem and Apple Support spent weeks on it and didn't get anywhere. I didn't have a problem with time machine files at all and was facing a complete reinstall when I came across a thread on another site. Someone there suggested unmounting any unused volumes that had not been ejected properly. (I did it a long-winded way, but someone else suggested the following is the way to do it correctly:
diskutil unmount /Volumes/Untitled.
Unmounting the volumes solved the problem for me instantly and it hasn't come back.
Probably a bit late but it seems like everyone has different problems, so thought I'd add what mine was, might help someone. I use Xcode a lot to build versions of the apps I'm testing in work. Each build added to the System Storage. I went to Users > <kramnadroj> > Library > Developer > Xcode and deleted everything from within the folder iOS DeviceSupport. There were loads of folders named after each iOS build (e.g. 11.2.1, etc.). Deleting all these freed up my storage from 90GB to 20GB. Hope this helps someone.
High sierra is a huge "cloud sync" os, but cloud actually means cached locally,
in the finder click Go, hold down the option key and you will see Library appear, go into library and look for a folder called Caches, command J and select calculate all sizes, give it a few mins to get the sizes of the directory,
if its large (normal size is 1-3gb) download and run onyx from titanium software, its free, and will clean you right up safely. install it ,go to "cleaning" , then the "user" tab, and select Execute. takes a few mins, then reboot. your good to go,
you can go through the other options of system/internet/fonts/logs/etc and let it clean you back up to a working fast Apple again. theres also a maintenance tab that allows you to clean things up a little further. and its safe, trusted and free, heres a link to the source page, choose the version for your OS version.
Thank you this worked, I had one time machine backup.. went from 84GB system to 30GB!
Thanks again!
Read the following thread and you will see the instructions given to me.
