I've been having this issue for a long time now. I have a Mac pop-up telling me that it's running low on disk space. When this occurs, VM Fusion has a message saying that I must free up X amount of space to continue running. I have deleted all of my music, there are no more pictures, and my documents only account for 31GB of memory. WHAT IS TAKING UP ALL THE DISK SPACE?!?! I have a 13" Macbook Pro, i5 prossesor and over 320GB hard drive. This is an early 2011 computer. Please help!!


MacBook Pro, Mac OS X (10.7.2)

    It probably has to do with your Fusion set up. Contact the folks at Fusion.

    There is a HTML 5 flaw in all browsers except Firefox that fills up boot drives, thus it's possible the virtual machine has this problem and Fusion is automatically allocating more space, thus the two warnings, one from Fusion and one from OS X.

     

    If you wisely created a earlier snapshot of the virtual machine, then copy files off the present one to a external source and/or reset the browser to hopefully reset the cache and restore the snapshot.

    I don't use any browser on the Fusion. I am running Windows 7. My problem now is that I can't even open the virtual machine because there isn't enough memory.

    I don't know if it a Fusion issue. When I "Get Info" under the users folder is says that my primary user has 293.4GB of HD used. But, when I add up all the main folders, I only get maybe less than 50GB. Where does it all go? "Why is the 'rum' always gone?"

    First, empty the Trash if you haven't already done so. Then reboot. That will temporarily free up some space.

     

    According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation. You also need enough space left over to allow for growth of your data. There is little or no performance advantage to having more available space than the minimum Apple recommends. Available storage space that you'll never use is wasted space.

     

    If you're using Time Machine to back up a portable Mac, some of the available space will be used to make local snapshots, which are backup copies of files you've recently deleted. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as "Backups." The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself.

       

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

     

    You can also use a tool such as OmniDiskSweeper (ODS) to explore your volume and find out what's taking up the space. You can 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.

     

    Proceed further only if the problem hasn't been solved.

     

    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.

     

    Triple-click the line of text below to select it, then copy the selected text to the Clipboard (command-C):

    sudo /Applications/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper

    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.

     

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

    I suggest you try a different Mail program as for any one person to have 250GBs of Mail files is just not right.

     

    Most emails are at most a few KBs, 10-20, and although you may get a lot of mail that has attachments those usually aren't bigger then 10MBs. So if all your mail had 10MB attachment that would be 25 Thousand emails.

    If most are only 10-50KBs then that number would go Way UP, into the Millions of Emails.

    Do you have 25,000+ emails, or Millions of Emails?

     

    I have 7 different email accounts and have been saving emails from the late 1990s and my total profile size for all the accounts is 229MBs of space used.

     

    This is another one of those Mac Mail bugs, along with a host of other bugs, that crop up causing the mail folders to grow in size for no reason.

     

    I've been running Tunderbird on both Mac and PC for welll over a year with no problems on Mac ort PC. No Can't Send or Recieve emails and no space being used up for no reason.

    Web based email rocks, why even bother downloading it to one's machine at all?

     

    This is another one of those Mac Mail bugs, along with a host of other bugs, that crop up causing the mail folders to grow in size for no reason.

     

    Sounds like one or more of the attachments or images might  have a end of file issue.

    One word of caution: depending on what caused the problem in the first place, all that data may be downloaded again.
