Stop MatLab freezing/hang up. HELP

I recently bought MatLab R2015b and now when I run MatLab it starts "Processing..." and hangs / freezes if I don't cancel it! 1) What does "Processing..." mean or what does it do? 2) MatLab CPU Usage goes through the roof while "Processing..." is running(e.g. 400%, generally around 2%). 3) The "Processing..." thing runs like every Minute.

Is there a solution how I can stop this "Processing..." or how to stop freeze while "Processing..." is running. Any help would be great cuz atm I can't use MatLab properly!

Where does the message "Processing..." appear? Which operating system are you using?

I'm running Mac OS X 10.11 (El Capitan) and the message appears at the bottom left in a yellow window.

Go in to your preferences in MATLAB and turn off Source Code Control.

[Aiven Timptner]

You, sire, are awesome! I called with both supports (installation & matlab) and none of them have heard of my problem or know what to do but your simple hint fixed this REALLY annoying problem in seconds! So simple, but so good. THX :-)

[Prasann Pandya]

I had the same problem and it got fixed using your solution! Thanks a lot. Btw, Does turning off source code affect anything? I am a newbie and just curious. Can you explain what it is for? Thanks

[Walter Roberson]

Source code control is for working on projects with multiple versions of files archived.

Thanks a lot!

[Aiven Timptner]

Thanks for your help but the support weren't able to help me with this. :/ But Walter Roberson fixed it! :-)

[Image Analyst]

How were you able to even get to the Preferences if it just hung immediately upon startup?

[Walter Roberson]

I gather from other people posting about the problem that it takes about 30 to 40 seconds before MATLAB becomes unusable.

[Aiven Timptner]

Yes and as I mentioned it was possible to cancel this thing. Than you have had like 1-2 Minutes before it run again "Processing...".

[Image Analyst]

So what was the root cause? Does Source Control just plain not work? Does it have a bug? Or is it working properly and you just have a massive number of files such that it took an incredibly long time?

[Walter Roberson]

I do see some people saying it works for them. I have not seen any postings indicating why this problem happens.
