pardon me for sounding stupid, but what is a cMP?
I never have understood the cryptic acronyms that are overused on the site for some reason. It hardly saves time to write the name of the product you are referring to so everyone, especially new users, may understand it.
There are “cMP”, “nMP”, “mMP”, “rMBP” and many others. It like some are in competition to see if they can make their version “stick” or something.
