It seems like it takes about 2 minutes for my Imac to start up.  We just got this in 2011 for Christmas and I know it was never that slow.  When I look at the memory, it is showing about 95% of the memory is taken up by video, however we have deleted any and all videos that we show on the computer but it is still showing the same amount of memory for video.  I am stumped. Any ideas??? where should I look for this mysterious video that is using all my memory?

    You are confusing hard drive storage space with operational RAM memory.

    So we can get accurate info about your iMac, go up to the upper left of the main OS X menu bar, click the Apple Logo, a drop down menu appears. Click " About this Mac"

    A Pop up window appears with info about your iMac.

    Gives us this info.

    Also, in this window is a more info button, click this and a new window opens with additonal info about your iMac.

    Cut and paste this info into a new reply editing out your name and the serial number of your iMac.


    Also, to determine how much hard drive space is left on your iMac's hard drive, locate your main hard drive icon.

    It might have your name on it or it might say Macintosh HD.

    Click once on the icon. Then use the keyboard and hold down the command/Apple key next to the space bar and type the letter I. An info box appears that tells you how much space is used up on the hard drive and how much space is still available.

    Thank you.


    Another question,

    Do you sync any Apple iDevices to this iMac?

    First, empty the Trash if you haven't already done so.


    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/

    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.
