I've installed Mac OS X High Sierra 10.13.4 on my MacBook Pro from the USB flash. While I installed the OS I chose APFS Encrypted file system on my entire SSD. Now I have my disk Encrypted (1.png) and my FileVault was Enabled automatically after installation (2.png) Now when I reboot the MacBook I have two option to logon: (3.jpg) 1) My User account "Alex": When I type the password for myself user I just login as usual. 2) Second "Disk password": When I choose "Disk password" I type the password that I chose for Disk encryption. After 30 sec downloading that option of Disk password just despair and I have just one option (1) "Alex" > I just put password for my account and login. There is no differences how did I logged in. The question is what the difference between these two login option? Also why am I actually able to login without entering disk password (1 option). Thanks.
