HT201364 how do I remove items from startup disk to load OS X Mavericks?

I'm trying to load OS X Mavericks and I'm getting a message to remove items from startup disk. Can anyone tell me how to do that??

For information about the Other category in the Storage display, see this support article. If the Storage display seems to be inaccurate, try rebuilding the Spotlight index.
Empty the Trash if you haven't already done so. If you use iPhoto, empty its internal Trash first:
iPhoto ▹ Empty Trash
Do the same in other applications, such as Aperture, that have an internal Trash feature. 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 the 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.
When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. 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. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Reboot and it should go away.
See this support article for some simple ways to free up storage space.
You can more effectively use a tool such as OmniDiskSweeper (ODS) or GrandPerspective (GP) to explore the 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. Note that ODS only works with OS X 10.8 or later. If you're running an older OS version, use GP.
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 or GP 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.
If you have more than one user account, make sure you're logged in as an administrator. The administrator account is the one that was created automatically when you first set up the computer.
Install the app you downloaded in the Applications folder as usual. Quit it if it's running.
Triple-click anywhere in the corresponding 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/OmniDiskSweeper.app/Contents/MacOS/OmniDiskSweeper
sudo /Applications/GrandPerspective.app/Contents/MacOS/GrandPerspective
Launch the built-in 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 to be careful. 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, sorted by size. It may take a few minutes for the app to finish scanning.
I don't recommend that you make a habit of doing this. Don't delete anything 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 the app, quit it and also quit Terminal.

  • How do i delete items from startup disk

    how do i delete items from startup disk

    You should never, EVER let a conputer hard drive get completely full, EVER!
    With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
    If it does, it's time for some hard drive housecleaning.
    Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
    Have you emptied your iMac's Trash icon in the Dock?
    If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
    If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
    If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
    Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
    Other things you can do to gain space.
    Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
    This app will help you locate files that you can move/archive and/or delete from your system.
    STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
    Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
    Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
    Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
    Download an app called OnyX for your version of OS X.
    When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
    Typically, iTunes and iPhoto libraries are the biggest users of HD space.
    move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
    If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
    Good Luck!

  • HT201364 How do I remove items from my start up disk to allow for the upgrade?

    I am being alerted to upgrading to Maverick, yet can't because my start up disk is full.  I have a new Air and plugged in my SlimDrive to access old documents and photos.  Ever since that, I get "full" messages and now can't upgrade.  Thoughts?

    After backing up:
    Empty the Trash,
    If you use iPhoto, there is a trash in that program.
    Delete the Trash in Mail.

    If you add an item to a slideshow, you'll usually see 2 entries for that image in the assets panel - one represents the thumbnail, and the other represents the larger 'hero' image.
    It sounds like you may have added the same image to your slideshow twice. You can select one of the hero images or thumbnail images in your slideshow and use the delete key to remove it. Then the extra 2 entries in the assets panel should disappear.

    how can i remove items from the list that have been deleted when i click on them it keeps showing folder empty

    Actually, Reader SHOULD keep showing documents that no longer exist, I disagree. It's no big deal, and people will quickly realise why they can't open the file. They open more files, the old ones move off.
    The REASON why it should not check is that checking whether a file exists can take a long time when things aren't good. For instance if a file server goes down, or a memory card is unplugged. That in turn would mean delays opening the File menu, and I've seen some software that can sit there for several minutes. That would really give people something of which to complain...

  • How do i remove items from my cloud

    how do I remove items from my cloud

    You'd have to go into the various apps on your device that store data on iCloud and begin trimming files.  For example, Contacts and emails that are stored on icloud, must be deleted using the Contacts and Mail apps.  Be aware that deleting data from icloud will also remove if from your device.
    Backups:
    Go to Settings>iCloud>Storage & Backups>Manage Storage; there, tap the device you need info on and the resulting screen lists Backup Options with which apps store data on iCloud.  Turn off camera roll and any other apps that might have a lot of data.  Then delete the backup.  That will free up space.  Photos should be regularly synced to a computer (like you store photos from a digital camera) using either USB via iTunes (on a mac use iPhoto or Aperture to move them to an album) or using photo stream. Go to Settings>iCloud and turn that feature on. 
    Emails:
    Regarding emails, on the computer, move emails from mailboxes in icloud to those on the device.  That can also save a lot of space.

    Don't buy CleanMyMac or any other dreck that offers to "clean" your Mac for you. Worst software ever.
    If there are apps in your Applications folder you don't need any more, drag them to the trash and empty the trash.
    In general, it is media files, like music, photos, and especially video that is taking up a lot of space. You can move your iTunes library, iPhoto Library, and iMovie video to an external drive.
