Hey guys I’m in a bit of a pickle here. I bought a 2018 MacBook Pro 13 from a forum member here a few months ago. Every was awesome till today when I attempted to boot off an external drive. I selected the external as my startup disk. When it loads, it hangs on the progress bar right at the end. So I try restarting without the external drive and a password screen comes up. I have no idea what the password is, tried guessing and nothing works. I messaged and emailed the seller a few hours ago, haven’t heard back. Hopefully he replies with the password or at least the receipt or invoice. Last resort is that this thing does have Apple Care Plus which covers damage after a $299 deductible.
