So, I messed up a bit. I encrypted the drive on my secondary Mac, but forgot to press save on my new password in 1Password. **** happens, I get it. I did remember to save the Recovery Key, to unencrypt the drive. I just don't know how or where to do it. Google and DuckDuckGo haven't been very useful in this regard. Could someone please point me in the right direction? Thank you very much .
