Black screen, Macintosh HD encrypted, FireVault issues
I have a series of problems with my Macbook Pro.
It started off with this: when I opened my laptop, it didn't wake up. First I thought my battery must have died (it was a possibility as I hadn't used it for 2 weeks) but once I was certain it couldn't have been the battery, I started my laptop again. I heard the power but had a black screen.
I tried rebooting the system: nothing. I came across someone saying "press the power button + s" then *press the power button until shut down* - wait for 15 seconds and press the power button again.
Progress! After waiting a while, a grey screen appears with apple logo and a gray loading bar. Once that's finished I immediately received the "forgot password" screen - which I haven't forgotten (at least, I know my account password and log in). No matter what I try, I get this screen. I tried to use the "forgot password" option eventually because I've been desperate and then it tells me that my FireVault key isn't enough for the volume on my laptop (huh??) so I have to use my recovery key I was given by apple...and I have to use this in the log in screen.
Thing is, I don't have a log in screen. I can't even go back with the arrows. And when I press "reboot" - the whole black screen issue starts all over again.
Second option:
I can click on the apple icon in the left corner after I have fixed the black screen issue but then it asks me to select a start up system (Macintosh HD in my case) so I select that, and it asks for my password because it's encrypted. OF COURSE, I've forgotten my password for THAT particular encrypted version. And there is no option as to say "forgot password, let's use recovery code" - which I have.
So...any ideas on what's going on and how I might be able to fix this issue? I'm breaking my head over my password for the encrypted macintosh hd but I do have my recovery code, just no where where I might be able to put it. Also, if you do enter this code, do you need to add the "-" between the series of letters and numbers or can I simply type in all the random things without the - as breaks?
All help would be welcome and appreciated! Thank you!
