Some time ago we began to ask questions about how to make the MacBook fans run a little quieter. Sometimes, users complained that the system was beginning to clearly eager to use the processing power, and after that began to spin more coolers in order to cool the processor. Why is this happening - a mystery. And not everyone there is a problem. However, poterzav little search engines, you can understand the problem, and the main thing - to solve it. If you have seemingly no reason spinning fans in your the MacBook, perhaps this article will help you.
So, the first thing you need to understand - why begins to warm up the processor and then start spinning fans. The easiest way to find it - to look into the monitoring system. It was there, sorting processes, it was possible to single out two of them: MDS and mds_stores, that consume CPU than usual. Both of these processes are responsible for the work of Spotlight. Well, then you need to disable Spotlight completely in order to find out whether or not because of it there may be our problem. To do this, enter the following command in the Terminal:
sudo mdutil -a -i on
And indeed, after a simple manipulation of the fans slow down the speed of rotation and started with his usual speed.
But here we encounter another problem: launching applications. Main my programs that I use most often placed in the dock - so they run much faster and more convenient. But those who used a little less, I run directly from Spotlight. I think so many people do: a simple key combination Control + Space and opens the Spotlight search line, which is enough to enter a couple of letters of the name of the desired application, and press Enter to confirm it run. Such a simple enough operation saves time and eliminates the need to search applications in Launchpad. However, if Spotlight is turned off all the convenience is reduced to zero.
Well, then there is another option that can help to disable Spotlight database and get re-re-index all the data in hand. Make it as simple enough in Terminal, enter the following command:
sudo rm -rf /.Spotlight-V100/*
Note that if you want to do this operation, it is best to run it at night or at a time when the computer will be free, as the process can take quite a long time.
However, this method also can not bring the proper result. So let's get on to the next. He's a little more complicated than for the insert operation in the terminal of one team, but the effect can be very positive. To Spotlight «Do not be crazy," you can add the exception for those folders that it will not be indexed. To do this, open System Preferences and go to the Spotlight settings menu. In the window that opens, select the Privacy tab and add those folders that Spotlight will not index. Especially useful to add a folder with frequently changing content (for example, the Downloads folder) and folders from an online backup (for example, Dropbox folder).
Usually exclude such a folder, the problem ceases to manifest itself: the processes do not consume more of the CPU, and the fans, respectively, do not start to cool it.
