Matlab 2015b on Mac Running Very Slowly

I recently installed Matlab 2015b on my mid-2012 MacBook Pro (2.3 GHz Intel Core i7 with 16GB RAM, running OS X 10.10.2 Yosemite). Opening the Matlab application takes ridiculously long, on the order of a few minutes. Once the GUI is open, typing in the most trivial of commands (e.g. "ls" or "pwd") is incredibly slow, causing Matlab to freeze. During this freezing, a small rotating wheel shows up in the bottom left corner of the Matlab console with a message saying "Processing..."

I had previously been using 2014b without any problems. It might be important to note that this 2015b version is a student version of Matlab that I purchased through my university.

I am not running any other applications concurrently with Matlab. What might be causing this issue?

Turn off Version Control in the preferences.

[Kristian Eschenburg]

Thanks! That worked perfectly. What exactly is version / source control?

Would you please illustrate how can I turn off version control? I am not able to find anything about this in preferences?

[Steven Lord]

Take a look at this documentation page. I don't think this process has changed in recent releases, so even though that documentation is for the most recent release it should still work for the last couple releases.

Turn off the version control really helped in my case!!!
