When I switch on I get a black screen with only the pointer
When I switch on I have a black screen with only the pointer showing. It happens every time.
I did a search and found a way to get back in... shutting down, then holding shift when I switch back on. Then typing username and password into the darkness. It works... till the battery dies, then it's the same each time.
I've had some trouble since a few times when I tried an old cinema display and adapter (with the macbook pro). Not sure if it's a coincidence. Also, it's been incredibly slow of late, despite 8GB RAM and plenty of HD space. Perhaps a separate issue though.
Any assistance would be gratefully received.
