This is a MacBook Pro running macOS Mojave 10.14.6 with FileVault enabled.
In my case the problem is that at the login page, when the computer starts, the admin user account doesn't appear but after logging in as standard user I see that there is an admin. My brother who created the admin forgot the password.
I was thinking to press command + S when the Mac starts , in order to create a new admin, but with FileVault enabled single user mode does not work.
Is there still a possibility to recover the admin password?
My question is slightly different than those for which it was marked as duplicate because in those answers are explained:
Single User Mode(Command+S). As I have explained in my question, with FileVault enabled single user mode does not work.
Recovery Mode(Command+R) . When in the terminal, in recovery mode, I type resetpassword I have not the possibility to choose the admin account but it's
choosen standard account and i think that if I reset the password in this way I will reset the standard user password and not the admin one.
