Q: After disconnecting target disk mode – Reset Password?!

After disconnecting my MacBook Pro from my second MacBook Pro, I cannot login to my first MacBook Pro.

 

After a long, delayed startup, I get a Mac OS X dialogue "Reset Password".

 

Why? What do do?

    Since I had NOT forgotten my password, I chose the third alternative "My keyboard isn't working when typing my password to log in". Then I asked to type in my password to disable FileVault. My password was accepted and I could log in.

     

    Now it seems as FileVault has started decrypting my SSD. Why? I don't need to decrypt.

     

    What do to?

    FileVaulted drives are very finicky beasts and with a reason: keep everything secure above all other considerations. What were you trying to do via Target Disk Mode? Apparently something altered the FileVault state, which triggered all the protection mechanisms. And since you told the system that there might be a hardware issue that can cause access problems in the future, it defaulted to making sure the contents were not lost due to insurmountable encryption. For now, let it finish unless you want to risk losing all the contents. Then you'll be able to reencrypt.

    Thanks for the reply Courcoul! It would now appear that FileVault has decrypted my SSD's contents, so may I proceed and turn on FileVault again? Nice knowing that I'm protected, even from the FBI.

    I'd restart in Recovery Mode, run Disk Utility and do a First Aid on both device (APPLE SSD xxxxx) and volume (Macintosh HD) just to be on the safe side. Click on Show Details for the minutae. If nothing turns up amiss, you're good to go and can redo the vault.

    Perhaps I should have done so, but I already started FileVault before receiving your (perfect) answer.

    On the other hand, I don't know where the "recovery key" was sent.

    If you are getting the FileVault password reset screen and do not need to reset your password then reset NVRAM.  Next boot after resetting NVRAM will display the FileVault login screen.
