Hello, trying to help a family member sort out an issue on their Mac, symptoms are taking around 6-7 boots to get to a working state. You get the black screen, apple sign and then the bar along the bottom that gets about a 1/4 of the way along and then the screen goes black and you have to switch it off from the wall, unplug and start again.
Here is the panic log :
