I tried searching to see if this appeared anywhere but was unable to! Basically, I can boot my MacBook and login but as soon as it takes me to my user profile the screen turns grey. I can't do anything except a force shut down. I can boot in safe mode, but that's not helpful for using my computer long term. Does anyone know why this grey screen is appearing? Unsure if this is a device or OS issue. This may be a related issue - my startup disk is full. If this is the issue, how do I get rid of 50GB of "other" without downloading a program? I just paid for a 256 GB 7+ so dropping another $1,500 CAD on a new MacBook isn't really ideal to me. Thanks in advance for all your help!
