Introduction to Yosemite Excessive Memory Usage and Leakage

Whenever any application runs on OS X, a memory slot is dedicated for its execution. If an application is occupying more than specified space for execution then system starts showing number of issues. When application completes its task the given memory is relinquished, if not then memory leakage occurs in the system. Mac OS X Yosemite high memory usage is a prominent issue; sometimes an application takes more space than allocated or is unable to free up allocated space that result in memory leakage. The memory excessive usage and leakage causes slower processing speed, freezing or pausing of the system due to which user needs to restart the system forcefully.

Indicators of Yosemite Excessive Memory Usage in OS X

  1. Errors indicate “Out of Memory”: System starts showing warning that mentions an application or a system is running out of memory.
  2. Unused program termination: OS X may terminate the applications which are open in background which are not in use. OS X shut them down to free up memory for other applications.
  3. Force-Quit window:
    • When system does not have resources or is low on resources, system will display “Force-Quit window”.
    • This window will display the system is out of memory and also show applications in paused state.
    • In the Force-Quit Window, all paused and not responding processes or applications will appear in red.
    • It will not mention the users about the applications taking more space. For this, user needs “Activity Monitor Utility” that will list applications by memory usage.
    • It also displays the applications that are taking excessive space in system’s memory. User can select these applications and forcefully shut them down.
