I don't see the hidden Library in that picture. The hidden Library folder within your home user folder can contain a ton of files especially if you back up any iPhones/iPads to your computer.


FYI, you will never be able to see/find all of the data on your computer. When I tried to investigate the storage on one of my Macs, I was unable to locate 30GB of data. Some of the data can be hidden in APFS snapshots associated with Time Machine backups and/or third party backups.

OmniDiskSweeper makes it so much easier to actually see & locate the largest files/folders.

I believe the Storage Management information is taken from the Spotlight indexing. You may need to rebuilt the Spotlight Index:

FYI, you can easily rotate pictures on your iPhone/iPad by using the information in the following Apple article, I'm sure Android devices have a similar option:

Also, if you take a screenshot in macOS you don't have to worry about rotated pictures.

As has been mentioned by @HWTech >> Disk Utilities will provide a far more accurate account of Used versus Free spaces


Image below is from a M4 Desktop running the current Sequoia 15.5


I do notice, from you last image, that the Drive Capacity is probable a 256 GB drive


Not to frighten you, but there is going to be a lot of work to keep the Empty Space at a more reasonable level


It is often suggested to keep between 15% to 20 % of the Entire 256 GB as Empty Space


You may wonder getting an External Drive and start moving ( Archiving ) unneeded Music, Videos, Pictures and large Personal Files off of the Internal Drive and onto the External Drive

The information in that Storage Management section does not mean the items stored in the "Applications" folder. And "Documents" does not mean just the files stored in the "Documents" folder. The values shown in the Storage Management section there are the items which can be identified as an application located anywhere on the Mac....same with documents.


When it comes to storage, the only important & accurate storage value is the Free space value which is only shown in Disk Utility and in the Apple System Profiler (aka System Information). All other storage related values may be misleading. It is just the way it is with recent versions of macOS & the APFS file system. Even the "Used" storage value can show more storage being used than the size of the physical drive under certain conditions.....again due to how the APFS works.

Crazy, I'm not sure how I ended up replying to @neuroanatomist instead of the OP. I meant to reply to the OP @evren257.


in answer to HWTech, this is what I can see from the Storage Settings in 10.14:

...and when you open the (info) button next to Applications, and sort by size, largest first:

Thanks, I thought that was the case, but nice to know for sure.

Thank you all for sparing your time to write under this post. Appreciate it. I checked application support, library caches, documents, many things but I cannot locate where are these files.


Are there any steps that I can follow to locate these extra amount?


I guess this is one of the downsides of apple thats I cant actually see what is occupying my storage.
