There are many things unknown that lurk behind the scenes.
The ability to monitor everything that’s happening inside is especially useful for those with slower machines.
They need all the juice they can get.
Running applications - even if they are in the background waiting - eat up system resources.
Hours are wasted everyday just waiting for the computer to repeatedly get back to its senses.
What’s even worse, some do this quietly without letting the users know.
So it’s no surprise if there are suddenly tons of applications appearing at start up.
The first step in taking control of the running processes on a Mac is to filter these self-added applications.
you’re free to do this in Mac by going to theAccounts Preferencepane.
This is the window display when I consciously open only one software - Firefox.
Just select them from the list and press the “Quit Process” button.
You could also terminate major applications viaForce Quit Applicationswindow.
Press “Command + Option + Escape” to summon the window.
But forcing the software to quit is not always the only answer.
Later on, when you want to use those halted apps, you might easily activate them again.
Something like Firefox with lots of open tabs.
I couldn’t find any native Mac OS X way to pause/unpause applications.
But I found an system calledPauserthat can do it.
It’s an old tool, but it works just fine under Snow Leopard.
Pauser will reside in the menu bar.
To pause any app, hit the icon and choose the app from the list.
Clicking the item again from Pauser list will unpause it.
The paused utility will be in the not-responding state and take zero amount of CPU processing power.
Unfortunately, pausing an program will not free the memory used by it.
Here are the comparisons beween active and paused Firefox.
