How do I get MATLAB to propery start up on Mac?

Initially on startup, Matlab would display itself for a moment on the dock (Mac) and then dissapear. I uninstalled and reinstalled Matlab. Now with 2013a installed the initial window square displaying the info about the program will come up and then dissapear. ------------------------------------------------------------------------------

When observed through the console, the errors produced were:

([0x0-0x67067].com.mathworks.matlab[2012]) Tried to setup shared memory more than once

[0x0-0x67067].com.mathworks.matlab: Unrecognized MATLAB option "psn_0_421991".

[0x0-0x67067].com.mathworks.matlab: Warning: failed to create preference directory /Users/morgansinko (1)/.matlab/R2013a.

[0x0-0x67067].com.mathworks.matlab: Check directory permissions.

com.apple.launchd.peruser.502: ([0x0-0x67067].com.mathworks.matlab[2012]) Exited with code: 1

------------------------------------------------------------------------------

After searching the web. I came across some advice to create a path to matlab which always results in "permission denied" The same is returned when attempting to go through cd to matlab and then cat >> startup.m . It always just reads "permission denied"

Please help

Is your username "morgansinko(1)"? Parenthesis in a username seem odd.

Does the directory /Users/morgansinko(1) actually exist? Can you write there?

Is there a /Users/morgansinko directory that's not being used for some reason? Can you write there?
