回答“Can it be upgraded?”Hi, David! Unfortunately, you won’t be able to swap the logic board from your MacBook Pro 15” Unibody Late 2008 or Early 2009, as Apple switches components and ports around to a point where you can’t actually fit older or newer logic boards with your MacBook Pro. I’d suggest you just buy a used newer MacBook that is compatible with the version of macOS that you would like, because it’d be more cheaper than trying to fit a newer logic board in your MacBook.
回答“Why dose my xbox have a red ring of death”Hi, Zach! A flashing orange and green light just means that your AV cable isn't connected properly. And just a note: a Red Ring of Death (RRoD) is a variation of red blinking or solid lights around the power button on the Xbox 360, not the original Xbox.
