    You need to delete some files to make room.  You should move items you don't use often to an external disk, then remove them from your hard drive.  You should empty your trash to make sure disk space is actually made available and you should compress folders on your hard drive you rarely use.  To archive (compress) right click the folder, and select "Compress" then delete the original folder:

    Finally you may need to migrate to a new hard drive that is larger.  To do this you would need:

    - an external enclosure

    - a new hard drive to install in your machine

    - install media for the machine (or the ability to net boot from the App store)


    Then you would install the new hard drive in your machine, then install the OS on the hard drive.  The use the migration assistant to move data and applications from your original drive.

    You will need to remove some files from your hard drive. Have you tried emptying your Trash? Many users put items in the Trash yet forget to empty it, not knowing that this is a necessary step to reclaiming the disk space used by the items in the trash.


    If emptying the Trash does not free up enough space, you may want to move some media libraries to an external hard drive. iPhoto and iTunes libraries often contain a large number of big files and as such are good candidates for moving. Do it like this:


    1. Attach an external hard drive to the MacBook Pro.
    2. Drag the library (the iPhoto Library is usually found in your Pictures folder, and the iTunes Library typically is in your Music folder) to the new hard drive. This copies it but does not delete the old library.
    3. Launch the application holding down the option key on your keyboard. You will be prompted to select the library you want to use. Select the one on your external hard drive.
    4. Test the new library thoroughly to make sure it works with the application.
    5. Once you are satisfied that the new library works, take the old library from its original location and put it in the Trash,
    6. Empty the Trash.
    7. See if the error you were originally having still comes up. If it does, you'll need to move other files.


    Best of luck.

    This is intended as constructive feedback (for whatever that is worth).


    I have read all the threads since 2010 regarding the error message: "Your Mac OS X startup disc has no more space available for application memory." The solutions suggested here are well intended and surely will help the folks with inadequate memory or memory usage problems.


    However, like some others who have posted here, none of the solutions posted here (since 2010) relate to my getting this error message. When I get this message, my Mac mini has no memory shortage, does not have too many applications running nor does it need the trash emptied.


    I am not a guru by any means, but I've been a Mac user since 1992. I can tell you that when I get this error message it is some kind of glitch -- an erroneous error message.


    I'm sure of this because when I restart my Mac, the problem goes away for several weeks -- then it comes back. I have checked my activity monitor and there are no issues with memory usage. 


    I suspect that some Macs develop a problem over time that causes this error message to pop up -- but it is not actually related to memory usage. It is an erroneous message, but I have no idea what causes it.


    Just my 2 cents worth.
