Thank you so much for responding.

Let me explain why I'm so concerned.

I DO BELIEVE that this dmd is being used to give a Remote Device
access to my iMac (I have no mobile phone paired with my computer,
yet everything RELATED TO an iphone keeps running in the 
background
along with dmd).

I also found these instructions on how to download & INSTALL DMD
onto Mac for the express purpose of using it to CONTROL DEVICE
MANAGEMENT. In many posts I'm finding online, it appears as though
"dmd" is an app that some Techies put on their macs, NOT 
indigenous
to Mac itself (**and of course I could be all wrong, but it 
bothers
me that when my iMac boots up it goes to a BLACK SCREEN for about
20 seconds before my landscape loads):

About the App

App name: dmd
Description: D programming language compiler for OS X
App Website: https//dlang.org

Install the App:

1. Press command + space and type TERMINAL and press enter/return 
key.

2.Run in Terminal app:

ruby -e '$(curl -fsSL 
https//raw.githubusercontent.com/Homebrew/install/master/install"
  2> /dev/null

...and press enter/return key. When prompted give password.

3. Run:

Done! You can now use dmd on your MacOs.
