Question Locked macintosh HDD after failed installation of update ?

[Gueri_x]

Hi all,

I have a macbook air (2018).

Yesterday I began the installation of the lastest update. The installation of the update failed every time I have tried, and I can no longer access to my hard drive (docs, etc).

I have tried to reboot the system but:

- I have no access to the macintosh hd since the locked hard drive doest not accept my password and neither the apple id can't unlock it. Thus I am not able to access to the terminal, utilities, etc. The curious is that my password is accepted when I normally launch the pc and the installation of the update and starts all over again.

- I have also tried to reboot thought internet and also this failed because of the same problem.

- I have tried to access the command + s, but also this failed.

- i have also reboot the SMC and the nvram with no success.

If I press ok after the message of failed installation, the boot disk option doesn't find the macintosh hd. But when I reboot the pc (command+r) the disk is fund but the password is not recognized by the system.

I look forward to hear from you.

Thank you so much.



Maria.

This may help (Apple forums link below)

It seems your disk became corrupted and required reformatting. That’s why the disk locked. To unlock the drive

• Start your Mac in Recovery Mode
• Launch Terminal
• Type mount -uw /
• Press Enter
• Quit Terminal and Restart your Mac

Hi, thank you for your reply, the problem is that I can't access to the terminal. Thus, I am not able to proceed with this.
