Returned the Laptop after it would not run on any OS before 10.15 and all my programs become expensive subscription services that are over priced and under valued for my business needs.  Nothing attaches to the machine.  You have to buy all kids of dongles or docks that hang off the machine in order to use any external drives, printers, SSD cards.  Touch bar is a waste of upgrade for apple.  You will never use the touch bar that is taking up real estate and increasing the price.  You work on the keyboard and look at the screen not the touch bar.  Better off buying a last Gen Mac pre touch bar.  I have bought 2 pre touch bar machines and much happier.
