System memory usage really high on Mac


MacBook seems to be very slow while processing. The activity monitor logo always shows that the memory is high. I felt worried about my MacBook being slow in processing. Finally, I found some good solutions to fix this issue.
Reason for this issue

  • This may be because of using older OS version.
  • Using different apps at a time.
  • No free memory left for processing.

Suggestions

  1. Upgrading OS ( for eg: if you are using OS 10.6.8 change to OS X 10.7.2).
  2. Use additional RAM memory.

Note: You can buy Crucial memory or OWC in online.
Here mentioned two options to check memory usage on Mac
1.Activity Monitor
Macbook Pro contains a powerful tool that allows the users to examine what’s going with your RAM. Activity Monitor is one of the excellent tools to check the memory usage on Mac.
How to open Activity Monitor
Go to Finder and choose Applications -> Utilities -> Activity Monitor. Check whether the ‘Memory’ tab is selected or not.
monitor memory
It contains a ‘Memory Pressure‘ graph at the bottom. This graph shows how the memory situation is

  1. Green – Memory resources that are available.
  2. Yellow – Memory-management process are asked.
  3. Red – Want to free up some memory space.

In that graph, there is an option “Memory used”.  It provides the correct figure about how much amount of space is consumed by apps and OS X.
The main use of Activity Monitor is it shows the what type of application currently running on your Computer and its memory usage.
Another way of identifying the information presented in Activity Monitor is going to column Real Mem. This label will display all the items from the list in an order by providing how much memory those applications are consumed.
Steps here to close all the applications that take more memory
Activity Monitor System Memory

  • Go to Activity Monitor and select All Processes.
  • Select Real Mem column.
  • If the column is not visible go to View -> Columns -> Real Memory from the menu bar.
  • Look at the process which is taking more memory. Shut down those applications.

2.iStat Menus

Below give some idea about how to reduce the memory usage on Mac
Shut out those Memory-take over Apps and Processes
Go to Activity Monitor and click on the memory tab it lists all the apps and processes that are running on your PC and also shows the amount of memory consumed for each app. It is one of the methods for identifying the apps that consumed the huge amounts of memory. Find that app and close them.
Way to close the app that consumed huge memory
The general way of closing the apps is to click on the red button in the upper-left corner. If you want to close an app in Activity Monitor click on the ‘Force a process to quit’ button (in the upper-left on the Activity Monitor window).
Activity Monitor is one of an excellent tool to clean your Macbook forever.

Stop apps from launching automatically
If you had a habit of selecting a ‘Log out’ without closing all the applications that are opened. That takes memory storage high. Open your Mac with a clean state, before that closed all the reopened windows and shut your Mac.
Sometimes some apps can be opened whenever your are switch on the system. That app can consume more memory.
How to prevent the apps from launching

  1. Go to System Preferences -> Users & Groups. Choose your account from the left side menu.
  2. In that choose the ‘Login Items’ tab.  This tab can show all the apps that are set to launch automatically. Remove that items from the list.

Note: Other apps that consume more memory

  1. Music players.
  2. Browsers (especially Chrome).
  3. Dashboard Widgets.
  4. Desktop Bling.
  5. Twitter Apps.
