Sorry for my late reply.
*When i look into "Disk Utility App" it shows, Used 102GB and Free Space 18GB. However, the "Disk Inventory X app" show as in the image below Used 69GB Free 18GB.

It seems the missing space is occupied by the Mystery upper "grey Box" in the image.

*Yes i have never "turn on" Time machine.

*What is "tmutil destinationinfo"? How to check for that (if need to use terminal, pse advise in command line)?

Appreciate your advice on this "irritating missing disk space mystery".

Regarding the "tmutil destinationinfo", i got this comments after i keyed it in terminal.

tmutil: No destinations configured.

diskutil list

This is what i got.

/dev/disk0
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *121.3 GB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_HFS Macintosh HD 120.5 GB disk0s2
3: Apple_Boot Recovery HD 650.0 MB disk0s3

What does it mean?

e result from diskutil cmd seems normal. hmm it all seems a little weird. at this point I would take a full backup, wipe n reinstall macOS then restore yr files. when reinstalling, check for any partitions n reclaim e space. did u install bootcamp for Windows previously? it could be a bootcamp partition.

I have no idea how to install Bootcamp. This is what i got when i Open Bootcamp assistant.

If i did install Bootcamp it may be too many years till i cant recall. However, the disk-space that goes missing happens only this year. How do i check if there's any Bootcamp installed previously.

Can someone who has installed Bootcamp, advise if the file (disk) size is ~24GB? I'm assume this maybe a way to confirm your "gut-feel".
