I have ben trying stuff out and there is always that 2.21 GB limit .

I tried the hdiutil command, as well as the hdid command, plus two 

applications, and the limit is always the same.

You will notice that it works for 4661736 sectors but not for 4661737 

I have attached a .zip with screenshots of the terminal
