Blackscreen issue I Tried everything....
hey guys I need help... When I use my macbook pro late 2013 there are times that when I turn it on it works perfectly fine but after some use lets say for like an hour to three hours and I decide to restart it it suddenly boots up into a Blackscreen. I tried to reset the NVRAM/PRAM and I also tried an SMC Reset as well and lastly I tried to reinstall OS but it would still boot up into a Blackscreen. But there are times like I wait a day and all of a sudden it would boot up normally.. Do you think the macbook has a problem with the connections or is this a temperature issue? I asked someone and he said it might be a GPU problem but when I connect my macbook to a external monitor it works fine.
