Sorry guy you ran out of disk space! You'll need to boot up under an external bootable drive so you can then access your internal drive to delete some stuff. You can try using a second Mac connecting yours to it using Target Disk Mode: [https://support.apple.com/en-us/HT201462|Use target disk mode to share files between two Mac computers] Or create a bootable external USB drive following this from another Mac: [https://support.apple.com/en-us/HT202796|How to set up and use an external Mac startup disk] Once you get access to your system use the other USB port to connect a empty drive to backup your stuff so you can delete as much as you can to free up space. A good rule of thumb is have 1/3 free for a 256GB or smaller drive and 1/4 for 500 GB and larger.
