Edit: After half day, my wife’s Mac started having the same problem. I have then applied the solution that I found in the Apple
Free System Resources Temporarily by Pausing Processes
If you are doing something CPU intensive, you have to start another operation in between. This can bring your system speed down to a minimum. To make sure that doesn’t happen, you can pause your processes in Mac.
Though CPUs of today are much stronger than before, but there are some processes that take all the processing time. For instance, let us say the iMovie app is exporting a heavy video you recorded. This could take many hours. This makes your system too slow to do anything else.
If something has stuck up your system, there is a method you can use to pause a heavy process so that you can do something else. And when your other task is complete, you can go back to the paused process.
- Open the Activity Monitor under Utilities.
- Now look for the process you wish to pause. Let’s say your iTunes is taking up too much time in conversion of 50 songs. Just note the process identifier (PID) of this program.
- Now open the Terminal under Utilities. Run ‘Replace PID’ and give the real PID you saw in the Activity Monitor. Enter this command kill- STOP <PID>
- When you enter the given command, it will pause the process. You will not lose any work. It will stay there- just paused. Now the Activity Monitor will display that CPU is free, and thus you can do whatever you want to on your system.
- After you are done with your current process, you can continue with the paused process. Simply follow the same process given in step 3. But instead of STOP, write CONT. Use the same PID and your process will be continued. Enter it like this: Kill- CONT <PID>
After this step, the system will start from where you paused the process and will finish the task.
Have you ever faced any situation where you just can’t work without pausing a process? What did you do in such a case? Write to us through comments.
