MAC: Write numberical dataset with string header row to .csv

I know this has topic has been broached in the PC world, so I apologize if this has been successfully addressed for MAC. I have seen a few convoluted options, though I have been unsuccessful in getting them functional for me.

I am attempting to write a dataset to a .csv file. This is a numeric matrix with a string header. I have made various attempts with csvwrite, dlmwrite, export, etc. I understand there are issues with MAC contacting Excel, but I wonder if there is a simple, elegant work around for this issue? Perhaps something I am missing?

Sorry, I know this is woe-fully rudimentary.

fopen() the output file and fprintf() the header into it. After that you have two choices:

1) continue onwards by using fprintf() to write out the numeric part, and then fclose() the file; or

2) fclose the file, and then use dlmwrite() with the append option to write the numeric part.
