Hi,

 

"Your Mac OS X startup disk has no more space available for application memory."

 

I am trying to free up space to stop this message from popping up on my screen. I've emptied my trash, but the problem isn't gone.

 

I have a iMac with OS X 10.6.8, with 4GB of Memory.

 

My local disk capacity is 499.76 GB and i am only using 179.07GB.

 

I am unsure how to remove temporary files, even though i am clearing temp files from my browser's history.

 

I don't know which program can be reliable and safe to remove the temp files for me

 

I'll appreciate if someone can help.

iMac, Mac OS X (10.6.8)

    Reboot to clear out virtual memory.

     

    Your problem is excessive swapping of data between physical memory and virtual memory.

     

    That can happen for two reasons:

     

    • You have a long-running process with a memory leak (i.e., a bug), or
    • You don't have enough memory installed for your usage pattern.

     

    Tracking down a memory leak can be difficult, and it may come down to a process of elimination. In Activity Monitor, select All Processes from the menu in the toolbar, if not already selected. Click the heading of the  Real Mem column in the process table twice to sort the table with the highest value at the top. If you don't see that column, select

      

    View ▹ Columns ▹ Real Memory

      

    from the menu bar.

      

    If one process (excluding "kernel_task") is using much more memory than all the others, that could be an indication of a leak. A better indication would be a process that continually grabs more and more memory over time without ever releasing it.

      

    If you don't have an obvious memory leak, your options are to install more memory (if possible) or to run fewer programs simultaneously.

       

    The next suggestion is only for users familiar with the shell. For a more precise, but potentially misleading, test, run the following command: 

    sudo leaks -nocontext -nostacks process | grep total

      

    where process is the name of a process you suspect of leaking memory. Almost every process will leak some memory; the question is how much, and especially how much the leak increases with time. I can’t be more specific. See the leaks(1) man page and the Apple developer documentation for details:
