i downloaded gimp shop for my macbook, thinking that it would be similar to a microsoft paint application, and after i realized that it was too complex for me to use i deleated it. upon installation however, i had to install something called x11 from the dvd that came with my macbook in order to run the application. now, after deleating the application i still get software updates for x11 and i am unsure what i should do... should i remove x11 from my computer and if so how or shoud i just update the software??
