Hi there,
I just upgraded my OSX to 10.10 and installed the 2014b. But the matlab uses about >100% of CPU after startup, and sometime it goes up to 500%..... and the matlab freezes up.
I do notice that on the bottom of "current folder" dialog, it says " getting status for files " and it keeps doing it.
Does any of you guys know what could have caused this problem?
Thanks,

The getting status for files message appears because of the Source Control integration in the Current Folder browser. Try disabling Source Control if you are not using it.
To disable Source Control:
  1. Click Preferences in the Home tab of the MATLAB Desktop
  2. Go to MATLAB > General > Source Control and select None
  3. Click OK
Now restart MATLAB and you shouldn't see a spike in CPU usage anymore. Let me know if you still do.

This fixed it for me. Is Mathworks going to get around to fixing the underlying problem? 6years later?

Hi all,
Same story here w/ updating to yosemite with r2014b - slow as molasses. This is ridiculous, particularly with any plots. Disabling source control helps to a minor extent.
Are there any work arounds or fixes?
