I am using a 13-inch MacBook Pro with macOS 10.14.6 (Mojave) installed. I am trying to utilize the Terminal, however, I cannot see any information in the terminal window. For example if I type
vim and press ⏎ Return, I can see that the program is open; it's identified in the window title, but nothing is displayed.
I have tried to restart my computer but this had not effect. To make matters worse the Apple menu with the shutdown commands is now blank when I open it and I am unable to shut down the computer safely.
