Perhaps if I explain, I am a user of Apple equipment, I expect it to perform well or, at least, as advertised. I don't have either the time or interest in what goes on in the background. I merely require the OS to deliver as offered. I find these pages interesting.
I do understand that there are many who are intensely interested in the 'nuts and bolts' of the OS and participate in the development through beta testing and I have no problem with this, especially if it results in a good OS.
A computer, tablet and phone are all tools to me, as are my camera, TV, Broadband, Car, Boat and Aircraft. If I needed to know the internal workings of each of these I'd never get round to using them.
By all means take a serious interest in the OS but please don't criticise those of us who merely use the equipment.
