I had an image from an older macbook (10.5.4) and I put it in a newer MacBook which I assume was could not boot as far back as 10.5.4, so I updated it by booting 10.5.6 on an external and running the combo 10.5.7 update on the MacBook's internal drive. I boot and after staying on a blue screen for a while, it goes black and shows me a command prompt and I can see all the processes starting up. then it goes back to blue and works normally. On shutdown, I see the prompt again. I cannot boot into safe mode or single user mode for some reason. When holding down the s and shift it still does the same thing. I can however still use option to boot from a different drive. The computer runs perfectly normally once booted. I just don't want to see the command line stuff. So is there some way to stop it, or hide it? Edit: I notice IGPU: family specific matching fails in the lines of code that come up, not sure if that is the cause.
