Macbook won't work with dock
why won't my MacBook work with the dock that connect to a monitor and a keyboard, and mouse when I try to connect it with the cable and it wont charge my laptop
Hard to say without any details or context.
What dock, make and model, is this?
Is it rated to output enough power to charge the Mac?
How is the dock connected to the MacBook?
Is the dock connected to a wall outlet?
Provide some details and someone may be a blessing to advise.
