MacBook Air Flash storage problem

So I just got a Macbook air mid 2012. It has 128 GB flash storage whilst running the latest Mac OS X Version 10.11.1 and the problem is that it is either showing wrong info or a lot of storage was taken over by something unknown. Apps took more than 50 GB of space even if there is no all the apps that are heavier than Microsoft Word and Excel. Acquired photos 8 GB and 4 GB audio which is totally false because there is not any music in there still. Please guide me in solving this problem.


For more information about the other category in the view of storage, see this support article. If the display appears to be inaccurate, try to rebuild the Spotlight index.

Empty the trash if you don't have it already done. If you use iPhoto, emptying his trash internal everything first:

▹ iPhoto empty the trash

In pictures:

▹ Show of the recently deleted ▹ file delete all

Do the same thing in other applications like Aperture, with an internal feature of the trash. Then, restart the computer. Temporarily, which will free up space.

According to the documentation from Apple, you need at least 8 GB of free space on the boot volume (as shown in the Infolog) for normal operation, not the mythical 10%, 15% or any percentage. You also need enough space to allow the growth of the data over. There is little or no advantage in terms of performance to get more free space than the minimum Apple recommends. Storage space you'll never use is wasted space.

When Time Machine backs up a Mac laptop, some free space will be used to make a snapshots the, who are backups of deleted files recently. The space occupied by the local snapshots is declared as available by the Finder and should be considered as such. In the view of storage of the information system, snapshots appear them as backups. The snapshots are deleted automatically when they expire or when free space becomes less than a certain level. You don't need to usually and should not, remove snapshots them yourself. If you have followed the bad advice to disable snapshots the running a shell command, you may have ended up with a large amount of data in the other category. Ask for instructions in this case.

See this support article for some easy ways to free up storage space. A common waste of space is old backups iTunes to mobile devices. As shown in this support article, select the devices tab in the iTunes preferences window, select the backup that you want to remove and click on delete the backups. Keep at least a backup of each device you use yet.

You can use a tool such OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the volume and discover what is take up space. You can also delete files with it, but not unless you don't know you know what you remove and that all data is stored safely. This means that you have several backups, not one. Note that CESO works with OS X 10.8 or later. If you use an older version of the OS, use GP.

Deletion of files inside a photo library or iTunes will damage the library. Such a library should be changed within the application that created it. It is the same for e-mail files.

Go further than if the problem is not resolved by the steps above.

ODS or GP can not see the whole file system when you run simply by double-clicking; He sees only the files that you have permission to read. To see everything, you must run it as root.

Back up all the data now.

Install the application in the Applications folder as usual. Quit it runs.

Triple-click anywhere in the row of the text below on this page to select it, and then copy the selected text to the Clipboard by pressing Control-C key combination.

For ODS:

security execute-with-privileges /A*/*/M*/* 2>&-

For PMS:

security execute-with-privileges /A*/*/M*/* 2>&-

Launch the Terminal application integrated in one of the following ways:

☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad and start typing the name.

Paste in the Terminal window by pressing command + V. You will be asked for your login password.

The application window opens behind other open windows. When you scan a volume, the window will finally show all files in all folders, sorted by size. It may take a few minutes for the app to finish scanning.

I do not recommend that you make a habit of doing. Do not delete anything as root. If something should be deleted, make sure you know what it is and how it got there, and then remove by safer alternatives. If in doubt, leave it alone or ask for advice.

When you are finished with the app, he quit and also to leave Terminal.

  • Can I reset my MacBook Air and restore the backup I made before to reduce others' storage space?


    so I have the 126 GB MacBook Air. My problem is that the other takes 87 GB!

    It seems that your screen displays some graphical anomalies when you connect to your user name. I would use these troubleshooting steps in the following article on the resolution of screens:

    Restart your Mac in safe mode to reset the default display resolution.

    If booting safe mode doesn't resolve the problem, reset your Mac NVRAM and SMC to reset the video ports on your Mac to their default values.

  • MacBook air water damage recovery of data flash storage of air from macbook to macbook pro retina

    Last week, I spilled water on my macbook air that extinguishes immediately after that.
    It's been a week that I let it dry without attempting to start.

    Unfortunetaly, I did have a backup for 2 weeks, (of course bad luck should come at the wrong time), and I really need to get my data from the flash ssd drive.

    I thought to transfer the player of Flash ssd of the macbook air to a macbook pro retina and retrieve the data since the macbook pro retina by making a backup. Would this work? This would not damage the macbook pro retina?

    I have a macbook air early 2014, the macbook pro retina is also the same year.

    Thank you very much for your answers.

    Best regards.

    You'd better using an external enclosure of the MacBook Air SSD rather than MacBook Pro.

  • How can I increase storage on a 13th 2011 macbook air?

    How can I increase storage on a 2011 13 macbook air?

    Buy a drive flash memory or if you need a storage more consider purchasing a USB hard drive. If you need a low-profile option, you can use an SD card but transfer speeds will be slower. You could get the updated DSS to level, but this will be done by a trained professional and would be quite expensive.                   -zerotwo77

  • MacBook Air storage issues - I have iCloud but using too much data, which is a better solution?

    I have a Macbook Air processor intel and storage 4 GB, I use iCloud for storing all my data, but recently I had a problem with too much use of my data internet home. We are limited because we live in a rural area. So I guess I have two questions: 1) can I use an external hard drive to avoid having to use my iCloud? and if I do which is the best to use external storage drive? I have a lot of files and photos, I am a real estate agent. I got this Macbook Air since September 2015 still invite us to her also. Next question, can I use another Mac with a bigger hard drive instead of the MacBook Air? My son told me in the Macbook air because of its features, but the storage for me is imperative. Please notify

    Use many small external drives that you can carry in your pocket that connect to the computer via USB 3.0. Shop for them at

    BTW, 4 GBs is the memory of the computer, no storage. MBA come with built-in SSD from 128, 256 or 512 GB capacity. You choose the MBA with the SSD model that best fits. However, once you make the computer cannot be updated.

  • Flash Player is not installed, even though said installed on MacBook Air. Can you help me please?

    I have a macbook air. My computer crashed 2 days ago and since I rebooted it, since 2 days I have ' plugins blocked» I installed, update... what he said I needed, although there was an option to pay for additional stuff I didn't pay. but the update was installed, didn't work. I uninstalled flash player and reinstalled twice, he still considered blocked. I closed and restarted twice, after uninstalling and after installation. No luck. I get a check for installation message that it is not on my computer, or I don't have the right to run. I read something on the search for programs on IE... but I use safari. I need help please.

The problem seems to be related to having to find the version 15.0. Nevermind, I lost two days trying to do what should be a simple update.

  • Enabling iCloud library fills a storage capacity on macbook air

    So I try to upload my pictures on iCloud to free up storage on my Macbook air.  Besides the fact that this process seems to take forever, I noticed when it goes I'm actually losing space on my hard drive.  This caused the upload stop and gives me the error message indicating that I have no more space on my hard drive and the process cannot continue.  I made sure the storage parameter optimize is on so that I do not download originals to iCloud.  Also, when I turn off iCloud, I don't have storage space.  So I have the feeling that anything that is uploaded is downloaded several times.

    So my question is what is being downloaded, and how to delete to free up more space on my hard drive?

    The use of the photo library of iCloud frees space on your Mac, it uses the same space, as it would if you do not use. So if you don't have enough space on your Mac to fit photos, you'll have enough space to use the photo library.

    Try another service for storage.

  • Problem installation el captain on Macbook air mid-2011


    I have a Macbook air mid-2011 running 10.10.5 2 GB memory and 64 GB of storage that seems filled with "other" most

    I tried to upgrade to el Captain but did not to enough disk space to install it then stopped the download.

    I have since created more space on the computer, but now to the upgrade of the software, he said 10.10 is already downloaded.

    However, I can find a way to find the download file to complete the installation.

    Please help if you can.

    Thank you

    You will find your original download in the purchase page of the App Store. Will need you about 20 GB to download and install El Capitan. You will also need about 4 GB of RAM, so I suggest the RAM upgrade if you can. You can visit OWC to know what options allowing the upgrade of RAM and disk space since you really don't have enough.
