# Multiple apps making your Macbook (intel chip) slow ? Try this.

During this summer when I was working on a project that required me to run IOS and Android simulators at the same time and on top of it screen sharing on zoom literally made my macbook cry. 

### CMD + Q
 I talked to apple support about this problem and they suggested me to **run fewer apps in parallel** and **quit all non required apps from memory**(cmd + Q). for e.g. if your machine has 6 core then run only 6 apps in parallel including the background processes. Not sure of the internal workings, but for me this wasn't the solution.  

Check this by going to *Menu > About my mac*

### Activity Monitor 
Next step - we checked the activity monitor - the process called **kernel task was hogging all the processing power** and was slowing down the machine ever further. I realised that this **kernel task kicks in whenever the machine starts heating up**. 

My colleagues who were working in an Air conditioned environment, their macbook performance was much better.  

### Turbo boost 
After googling a lot I read somewhere that there is a feature in mac with intel chips called **Turbo boost** which runs behind the scene and allows the mac processor to run at higher frequencies. 

I installed a tool called [Turbo boost switcher](http://tbswitcher.rugarciap.com/) and turned off the turbo boost feature.

This significantly improved the performance of my machine. I was able to work on multiple simulators without any heating issue. Please give this a try this may solve your problem too. 

### Thanks !
