If FileVault is enabled, it will indicate that disk encryption is active.
Disable FileVault to ensure boot continuity
Open System Preferences.
Click Security & Privacy > FileVault.
Click Turn Off FileVault.
Enter the administrator password if prompted.
Allow the decryption process to complete.
Reboot and verify boot success
After turning off FileVault:
Reboot your Mac mini and confirm that it starts up without requesting the FileVault password.
Test remote access via SSH or VNC to ensure connectivity remains available.
Important
If FileVault is enabled and your Mac mini reboots unexpectedly, you will be required to enter the FileVault password manually. Remote access will not be possible until the disk is unlocked, and you may risk data loss.
