    My kids wanted to play a Windows game so I tried to instal Windows 10 education edition on our iMac, using boot camp, it did not work the first time, second try 95 Gig or so was created but reboot of windows to instal it did not happen. So I deleted the partition using boot camp but the portion space disappeared !
    the system is taking unusual amount:


    so ran the following command:
    DocIMac:~ Doc$ sudo du -d 1 -x -c -g /

    1 /.DocumentRevisions-V100

    1 /.fseventsd

    Not sure why what is wrong and how to reclaim the 95 G that vanished after deleting the boot camp partition
    Any help is appreciated

    Also here is the diskutil list:

    Such are the hazards of messing with BootCamp.

    There may be some tricks using the terminal to get it back, I don't know them, perhaps others will help.

    But.. if that doesn't work...

    The one "sure way" to get that space back is to do the following:
    1. You'll need an external drive large enough to hold the contents of your Mac partition.
    2. You'll need CarbonCopyCloner (free to download and use for 30 days)
    3. Once you have that stuff, do this:
    4. Use CCC to clone the contents of your Mac partition to the external drive. A TIME MACHINE BACKUP WILL NOT DO.
    5. Now, BOOT FROM the external cloned backup (restart, hold down option key CONTINUOUSLY until the startup manager appears, select external backup with pointer and hit return)
    6. Once you're booted from the cloned backup, open Disk Utility
    7. ERASE the internal drive to "Mac OS extended with journaling enabled".
    WARNING WARNING WARNING
    I don't know how this is going to handle the fusion drive. It may keep the fusion setup, or it might "break" the fusion drive into "separate" HDD and SSD portions. Not a fusion drive user here.
    8. Now, the internal drive is "empty". It's time to rebuild it.
    9. Open CCC. Put the backup "on the left" and and to its right select the internal drive "as the target".
    10. Accept all CCC's defaults and let it RE-clone the cloned backup BACK TO the internal drive.
    11. CCC may ask if you want to clone over the recovery partition as well. YES, you want to do this.
    12. The re-cloning may take a little time (depending on "how much stuff" was on the internal drive to begin with)
    13. When done, power down. Disconnect the backup.
    14. Press the power on button and again hold down the option key to invoke the startup manager. Select the internal as the "new" boot drive and hit return.
    15. Do you get a good boot? You're almost there
    16. Open the "startup disk" preference pane and RE-designate the internal drive to be the boot drive. That should do it.

    Oh, and just one more thing:
    Next time the kids want to fool with BootCamp, just say NO.

    thanks for the reply, hopefully someone with knowledge about Fusion drive will give some advise as well in next few days, else will take chance and follow your suggestion.

    What OS? Yea, it's important. If High Sierra or Mojave, restoring that space is a time consuming PIA involving Terminal and Disk Utility. Often the easiest way is to wipe the system, reformat and restore from backup—with Snapshots, this is easy.

    it is macOS High Sierra (10.13.6), had a time machine back up before trying the partition and also made a back after the event as my kid had done some project with lots of graphics, but this backup seemed to also use that 90 G lost space as well 9the back up size was about 99 G)
