I have a Macbook Pro and want to install MATLAB.jl.

The instructions say this:  
`You may add the following command to `.profile`:`export MATLAB\_HOME=/Applications/MATLAB\_R2012b.app` .`

Should I do this through Julia or my Terminal?

Where is the file `.profile`? At /Users/FirstLast/? I do not have that hidden file here unfortunately.

The sentence I should add is the below, based on my Matlab version?  
`export MATLAB_HOME=/Applications/MATLAB_R2012b.app`

Just in case: have you checked if it’s in your default home directory? Otherwise, try to create such ` ~/.profile` startup file with said instruction.

Got it. Thank you for the clarification!
