So I wanted to install Kali Linux on my Macbook Pro, I went through the installation well until I got to the login, once I enter my details and click login I will get a grey background and nothing else, couldn't do anything. So I rebooted got up to the bit where it asks for the username, I open the non-gui instance of Terminal and use
apt-get update && apt-get upgrade && apt-get dist-upgrade
and rebooted, and ever since then I boot into a black screen with a underscore at the top left. I've searched all over Google and tried dozens of solutions and nothing has worked. I have tried reinstalling, multiple times, I attempted to install Nvidia drivers but it just says unknown package using
apt-get install Nvidia-kernal-dkms
Any help would be appreciated.
