I have deleted all the files under User folder, but it still says that it uses ~60GB of space. Real usage is ~2MB. There are no more files to delete. Is there any hidden files i am not aware of. If yes, how i can delete them?

DiskWave view

I do not want to delete the user account. I just want to get rid of information that is useless, but I don't want to mess up my Mailbox or other stuff, so I want an advice if it's safe to delete some parts of those folders.

    Have you emptied the Trash? – sayzlim May 30 '14 at 16:00

    If you go to the library folder inside your user folder (Finder > Go > hold option and select Library) you can press command+I to see it's size. I'm willing to bet this is where the bulk of the data is. Beyond that I'd wager that you're using Gmail along with Apple's Mail application and that the Mail folder inside your library folder (~/Library/Mail) is very large. – Mr Rabbit May 30 '14 at 16:11

    @GeorgeGarside - Outside of using Single User mode when you first boot there is no way to delete your user account if it's the only account on the Mac. Beyond that it's impossible (or at the least pretty foolproof) to delete the user account that you're booted to. If there was a second admin user account you could login to the second account and delete your primary account, but not while logged in as yourself. – Mr Rabbit May 30 '14 at 16:13

The space is most likely being occupied by the various files and folders in ~/Library, which is hidden by default on OS X. You can show the Library folder by navigating to your home folder in Finder, pressing ⌘J and showing the Library folder.

Furthermore, you can run the following command in your home folder which will list all the files and folders in your home folder, including hidden files and folders, and display their sizes.

du -shc .??* *

Rebuild your Mailbox. You can do it by running Mail, and select Mailbox » Rebuild from menu bar. This’ll remove all the attachments in all your signed in accounts.

As for the massive file size in ~/Library/Application Support, you have to figure out which apps taking up the largest space. Run these apps and try to reset the caches with the built-in options or menus. If you still can’t find one, consider remove the largest file (not entire folder).

Take time to skim through the list and delete folder where apps are no longer installed (usually they’re named after the app name). It’s possible that you didn’t remove apps correctly before.


In Yosemite if you use iTunes and have an iPhone - release your older backups - they are categorized as "other" storage on your hard drive and if you have a larger iPhone the backups can be 20+ gigs.


I was having a similar issue. I had over 60 GB of "movies" that I couldn't find anywhere. It was actually in my recently deleted album of my photos. If you double click albums, you should see one that says "recently deleted". There was 57 GB in there. I permanently deleted them, and problem was solved.


Not sure what you trying to accomplish here, and I would not trust the DiskWave.app to be accurate.

I strongly advise you not to delete hidden files.

There is a reason they are hidden.

If you must see them in Finder, run the following in Terminal.app:

defaults write com.apple.Finder AppleShowAllFiles 1 && killall Finder

To reverse that, use this command:

defaults write com.apple.Finder AppleShowAllFiles 0 && killall Finder

This was killing me too. I resorted to doing a clean reinstall. Not even a simple reinstall (the one where there's no formatting of the hard disk) would get rid of the infamous "60GB". Now it hovers around 10GB, but I chose not to use iCloud at all. You turn that on and things start to get out of your control. I prefer Dropbox; at least I know that what I put there is what I'm backing up.


I had a similar problem - my folder usage was 20GB when I look at my user directory. Use muCommander as root (sudo) and check this folder again.


Many many files and folders system hidden. You can show and check your capacity. In Finder show hidden system: View -> Show System Files

Or you can get information about capacity in your profile user by open Terminal and type:

du -shc .??* *

Well, I had similar issue in my Download folder. Many times I got the message 'Startup Disk is almost full'. Finder was showing 37 GB in that folder, but, checking each subfolder individually, the size of all was like 10 GB smaller.

So, I could not (yet) figure out why it happens, but, I could find out how to fix it.

The only matter is the problem may keep showing itself up.

So, to fix this, go to 'System Preferences' -> 'Spotlight', then, 'Privacy'.

Click on the '+' button, and add the disk which contains the 'wrong sized folder'. Hit OK for confirmation.

Reboot your Mac (when I learned about it, this step was not mentioned. I did it on my own, just to make sure).

After the reboot, go back to system 'System Preferences' -> 'Spotlight', then, 'Privacy'. Now, click in a disk you just added, and remove it (using the '-' button).

And it's done the trick.

PS 1: MacBook Air 2010, OS X v10.8.5 (Mountain Lion), 256 GB SSD

PS 2: Sorry, I do not remember where I learned it, but, in the worst case, you will lose a bit of time while OS X rebuilds the file indexes to improve spotlight search.

PS 3: If you realize the spotlight is not searching how should be, it is a signal that above procedure should be executed.

PS 4: Another tip that may be helpful: Go to Disk Utility, select your disk, and hit 'verify disk permissions'. After done, click in 'repair disk permissions'.


I had the same issue. I used the terminal command du -shc .??* * to show hidden files and looked in the LIBRARY folder in the User folder. Under Application Support was where all the space was being used. A Folder called ILIFEASSETMANAGEMENT . There were a lot of pictures in there. I went into SETTINGS and under iCloud Photos Options , turned off PHOTO STREAM. Bingo..got all my space back.


I recovered somewhere in the neighbourhood of 80 GB yesterday by running Onyx and removing OS X's file versions which causes a fair amount of bloat well beyond regular cache cleaning.

Of course, backup/be careful use at own risk, but: http://www.titanium.free.fr/onyx.html


In my case, The real culprit was 2 .err files under the following path /usr/local/var/mysql/ which were taking about 45 GB and 4 GB respectively.

After deleting this files I immediately recovered around 50 GB of data. Hope this is of use to someone.


There is a nice program for Mac called CCleaner. While I was a Windows user, CCleaner was a great companion, deleting thrash files and cleaning the registry. ^_^ (well, OS X has no registry...)

I run CCleaner every day, before shutting down my Mac. https://www.piriform.com/mac/ccleaner

  • so what do you clean n Mac ? – Ruskes May 30 '14 at 20:15

    I don't recommend using CCleaner on a Mac. Furthermore, this program is of no specific help to the OP in this case. – njboot May 30 '14 at 20:21
  • @Buscar웃, basically internet thrash files (cookies), recycle bin. Although CCleaner is not very complete, it's free! – Eva Thyssen May 31 '14 at 1:44
  • Cookies do not make your computer slower and do not occupy much space, but their absence makes browsing somewhat more bothersome, because all login credentials etc. are gone. Trash is cleanable by single right click on the Trash and choosing "Empty Trash". – Rilakkuma Feb 24 '15 at 6:53
