System is taking up storage.
try the following
Start your mac in Safe mode, you may have to look up the key sequence for your macOS.
Check your storage About This Mac/Storage etc. (In safe mode, mine showed accurate usage)
Restart in normal mode
Repeat step #2.
You will have to do a manual search of your profile folder then to see what is filling up, then delete from there. I'm not sure exactly where.
When my computer fills up. My time machine backup got redirected to local storage instead of my usb HD. This happens when I'm not connected to the drives for a long period of time. Time Machine runs and decides to create backups on the local machine.
I will try and see what can run to help identify large files on your machine.
try and run the following
sudo du -sm *
this should show you where the majority that file space is in the directory structure.
This will allow you to drill down and see what is eating your space
Thank you for your reply. I have been searching for files but honestly, I don't know where to find them. I have tried log files and caches and delete them. Still, a few MBs was freed. I try the command you gave and let you know the results.
I will be waiting for you on how to run and help identify the large files.
Appreciating so much for all your help.
I tried to run the command you sent and did not found any file that is eating up space.
I tried to download third-party software by deleting some apps. When I run 3rd party apps
like clean my mac. It does not show any big files. The junk files were only about 5Gb and that's it.
But the system files is still the same after cleaning it,
Do you have any possible solution to solve this?
I was hoping that would be enough...
but you can also try theses:
List files and folders - totalling the size to include subfolders:
du -sk * | sort -nr
List folders and hidden (system folders) - totalling the size to include subfolders:
du -d 1 . | sort -nr
List the 10 largest subdirectories in the current directory:
du -hs */ | sort | head
