About This Mac is showing wrong Storage information

When I look to see how much my App, Movies, Photos, Autos, and Backups the GB being listed is wrong. I have a 120 GB hard drive. My Apps are claiming to be 130.43 gb, Movies at 22.13 gb, Photos 18.48 gb, Audio 1.17 gb, Backups 217.9 mb. It states that I have 47.73 gb of 120.1 gb available. Is there a quick fix for this, or will Apple need to create a fix?

MacBook Air (13-inch, Early 2014), OS X Yosemite (10.10)

I have the latest Macbook Pro, purchased in 2015. I think it's identical to yours. I've had this problem in the past, re-indexing has helped once, but now re-indexing will add around 5gb to my available storage, instead of the 100 or so it says I'm using. I've been through every single file possible, and collected info regarding usage on almost every single folder, however the information I obtain does not equate to what's being displayed in "About This Mac". This issue is just ridiculous, and needs to be fixed. We, as customers, shouldn't be needing to constantly re-index our computers just to see storage information; I have better things to do, being a student with barely any time.

Just used OmniDiskSweeper; In total it says I use 141 gb +. Whereas "About This Mac" claims I'm using 229 gb, 129.67gb of that being marked as "Other". As stated previously on comments (on this thread), I've manually sweeped through a majority, if not all of my files and none of the values I calculate add up to "20.04 GB free of 249.79" (shown in picture above). I have re-indexed on multiple occasions in the past year, all with no success, partially excluding an attempt made (which didn't even work). I run the latest version of OSX, I have no applications that could be possibly hindering my storage calculations (is that even possible), and I have the latest Macbook Pro (13 inch, 250GB, 2.7GHz Intel Core i5 processor, 8GB memory). Please someone help me.

and... now (tried the suggestion) it reads that I gained 2.~ GB (went from 17.xx free, to 19.xx free) and EVERYTHING list as other....

Uploaded 20 gigs of pictures to Flickr, uploading more, deleted the parent files after the upload, have deleted every document on this thing, except for 40-50 one page PDF's.

and Pics, (before it went all yellow) showed about 40-50 gig....

Spotlight re-indexing never helped me much either; if Spotlight is a cause for this problem, it's clearly not the only cause. The only fix that ever works for me on any repeatable basis is turning off local backups in Time Machine (if the settings say they're off, then I turn them on, let the setting "take", then turn them off again). AFAIK Apple still doesn't provide a GUI interface for this, but it can be done in Terminal or by any of about a zillion different utility packages (I recommend OnyX, which is free).

Having the same issue.


Has this not been fixed yet?

10.10.5


My problem started today, i had about 900gb free a week ago. Today i get Startup disk errors stating my space is low. I check and it says i have 10gb free, which is IMPOSSIBLE, i keep majority of my files on my 2tb External. I know for a fact i have about 120 gb used but the rest is definitely unaccounted for. My computer shows 1tb Used!


Tried everything listed on this board, nothing has fixed my problem.

Oh well, it seems that users' content is not being calculated for sessions you are not logged in. Having different softwares with large database located under various users makes it a puzzle to display the overall HD size, eventhough you are logged into the admin session.

Therefore, my issue seems to be related to displaying the total breakdown for storage used accross all users' sessions rather than a miscalculation of the storage space.

I realized that when trying to manually backup all my folders on an external HD.


I apologize for the tone of my initial post.
