Matlab installer uses over 100% of my processor!! causing fans in laptop working so loud it feels like its gonna explode ;)

There must be some problem with the Matlab installer (R2016b) for Mac (in my case it is macbook pro retina with osx 10.11.6 El Capitan) because it gets very greedy when it comes to using cpu. It is just a downlading process and it uses literally 120% of my cpu coasing Fans get loud.

I am having a similar experience on Ubuntu 18. It says it is downloading the components, Simulink etc, and very slowly, at about 1Kbs, but it is causing my laptop to overheat, which it almost never does.

The solution to this could be

1. installing cputhrottle from http://www.willnolan.com/cputhrottle/cputhrottle.html_or using command _$ brew install cputhrottle in terminal (assuming you have brew installed).
2. find out what is PID of Matlab installer (e.g. Activity Monitor -> CPU)
3. using command *$ cputhrottle PID 50*in terminal (where PID is Matlab installer PID number) and 50 is 50% (or you can use other number between 0-100)
4. this should work :)

All this power is used just for displaying the progress bar.

Hide the installer (yellow button at the top) and all is normal again.

where is the yellow button? is this applicable to windows 10?

There is nothing to fix. The fan is there for a reason: so your computer won't explode. Don't worry about it - it won't explode.
