I have a huge memory allocation defined as "other" in memory storage. I have read and tried most of the stuff Pondini sugests on these links: and I think it has something to do with my Time Machine. It backs up to an external disc but I'm thinking it might leave stuff around.


I don't work off the boot drive, Mac Daddy SSD. Only operative system and apps are on that disc. Yet, "other" is huge!


Things I've tried:


1. All the stuff I've seen in this forum on this.

2. Disc Utility - verify repair of the boot drive (while booting on another disc).

3. Reset Time Machine.

4. Checked Console to see if I could find any weird files to delete - but that **** was hebrew. Nothing deleted.

5. Asked the geniuses at Apple service center - they thought I should get a bigger disc. I don't agree because I'll just get the same problem again - only later.


What to do?


Please help!

    Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:


    iPhoto Empty Trash


    To locate large files, you can use Spotlight. That method may not find large folders that contain a lot of small files.


    You can more effectively use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can also delete files with it, but don't do that unless you're sure that you know what you're deleting and that all data is safely backed up. That means you have multiple backups, not just one.


    Deleting files inside an iPhoto or Aperture library will corrupt the library. Any changes to a photo library must be made from within the application that created it. The same goes for Mail files.


    Proceed further only if the problem isn't solved by the above steps.


    ODS can't see the whole filesystem when you run it just by double-clicking; it only sees files that you have permission to read. To see everything, you have to run it as root.


    Back up all data now.


    Install ODS in the Applications folder as usual. Quit it if it's running.


    Triple-click anywhere in the line of text below on this page to select it, then copy the selected text to the Clipboard by pressing the key combination command-C:

    sudo /Applications/

    Launch the Terminal application in any of the following ways:


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


    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.


    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.


    Paste into the Terminal window (command-V). You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.


    The application window will open, eventually showing all files in all folders. It may take some minutes for ODS to list all the files.


    I don't recommend that you make a habit of doing this. Don't delete anything while running ODS as root. If something needs to be deleted, make sure you know what it is and how it got there, and then delete it by other, safer, means. When in doubt, leave it alone or ask for guidance.


    When you're done with ODS, quit it and also quit Terminal.

    I read that link before. Nope.

    Hi Linc Davis!


    Thanx for your input. One of the first things I did was to delete previous imports and trash in iPhoto.


    I did what you said and this is the heavy stuff OmniDiskSweeper shows:

    Screen Shot 2013-10-22 at 9.55.34 AM.png

    I already store the iTunes 50GB music on a different drive than the boot drive.


    In ODS, I see my MobieSync backup probably should be altered. I've searched the forum for how to do this but all I find is info on moving iTunes-files to another drive than the boot drive. As I already have it set up like that, I don't know what else to do?

  • nbar Level 5 (6,980 points)

    Those are backups for your iOS device. The 'nope' implies a cursory look at the link I pointed you to, which includes, in the Xlab FAQ's:



    Remove old iOS device backups

    Apple iOS® devices (iPad®, iPhone®, iPod touch®) automatically back up specific files and settings to your Mac whenever they are connected to your computer. The backups are saved in your Home > Library > Application Support > MobileSync > Backup folder. While you should retain your most recent backups from these devices, older backups can be deleted in the Devices pane of iTunes preferences. For details, see the following AppleCare Knowledge Base documents:

    Thank you so much for your input Nbar. I am redaing the stuff on that link and I still don't understand what it is I should do.


    I don't even understand how to find Home > Library > Application Support > MobileSync > Backup folder. I find the Application Support folder but there is no MobileSync in it.


    Feeling blonde...

  • nbar Level 5 (6,980 points)

    Don't put yourself down, especially with outdated sexist stereotypes .


    From the finder menu bar, Go > Go to Folder... > ~/Library/Application Support/MobileSync/Backup/


    Copy and paste the bolded path into the finder window. Be sure to include the '~'.  This will open the folder with your mobile backups. You can either trash them all, or trash all but the most recent. Empty your trash. That will free up a good 10-15 GB...


    Consider an alternative location (iCloud) to backup your iOS device to.

  • Lobsterass Level 1 (0 points)

    OK. Thank you! I did that and it cleared 12GB or so. Nice! What else can I do? It's still plenty of "other" hogging up space on my drive.


    Also, is there a way to back up my iPhone to one of the other drives? I mean, I don't wanna pay for storage on iCloud as I have 2,5 TB storage drives on my computer.

  • nbar Level 5 (6,980 points)

    To my knowledge, there is no way of changing the default location of iOS backups on your computer. Reboot your machine, to begin with. I notice your 'private' folder was very large. Rebooting can sometimes reduce the size of this folder (specifically, the /var and /tmp sub folders) within it. See the improvement and go from there.


    I don't usually recommend this, but download ONYX as you probably have a large amount of cached data and log files that are taking up unneccessary space. You have to be careful using the program and only perform specific cleaning tasks. Below are the options I would recommend to begin with:

    Cool, that deleted another GB.

    Screen Shot 2013-10-22 at 11.30.34 AM.png

    I kind of feel like there should be more stuff I could do. I still have 53GB in "other". Nbar, you created a monster - me! I'm obsessed with deleting stuff now.

  • nbar Level 5 (6,980 points)

    " I'm obsessed with deleting stuff now."


    Haha, be careful...


    Another thing I noticed...some of that 'other space' isn't actually 'other'. I think finder isn't correctly representing your disk usage. Reindex spotlight and see if anything changes...I must be off to sleep soon, but will get check the thread tomorrow. Read through the rest of the links for further guidance! Best of luck.

  • Lobsterass Level 1 (0 points)

    Did the Spotlight thing already. OK! I'm gonna let you go but since you seem to know it all, I wonder if you know how to allocate more or less RAM to an application?

  • Lobsterass Level 1 (0 points)

    Sorry, I found out you change the memory allocation on scratch discs in each app's preferences now. Never mind! Still, I "only" have 40 GB free on my boot drive because I just made one iPhone backup. Should I buy a bigger SSD?

  • The hatter Level 9 (60,930 points)

    Use this one for backup or scratch, but yes, prices and such make a Samsung 250GB EVO a nice addition to any system (500GB for $330 ain't bad either). I aim for about 50% free on SSD, still use TRIM Enabler 3.x and run DU from another hard drive every couple weeks so DU can TRIM blocks.


    If the home account isn't on the boot drive and you set ~/ to another volume, I cannot understand why it would not follow that iTunes would use boot drive. In fact I personally think it should stay or follow wherever the iTunes Media folder is located. That or ~/Library/Application Support/ in your home account folder.
