    High Sierra 10.13
    Mid 2010 Macbook Pro
    Only 1 boot partition: "Macintosh HD" APFS
    No Boot Camp
    No firmware password
    No FileVault
    Yes Automatic Login enabled

    Priority:
    Not urgent, but is a nuisance

    Problem:
    Reboot or Power ON results to default booting into Startup Manager after the "chime sound"... 100% every time. Have to select "Macintosh HD" every time.

    Attempted:
    Cleared NVRAM & SMC.
    Checked faulty OPTION key.
    CONTROL clicked "Macintosh HD" in Startup Manager.
    High Sierra > System Preferences >Startup Disk > Selected Macintosh HD MacOS, 10.13.
    sudo bless -mount "/Volumes/Macintosh HD" -setBoot

    Not yet attempted (Last resort)
    Reformat entire SSD, and clean install


    Anybody encountered such a glitch before?

    Did you select your hd in startup disk and then press restart?

    Yes. Done that.

    Would be great if there is a terminal command to fix this.
