Do NOT Install Apple MacOS High Sierra Supplemental Update. NO NO NO

Screw it. Wait for the next major release of High Sierra update and avoid this piddly little patch.

If you have an old 2011 Macbook Pro 17″
You will be very sorry if you install the High Sierra Supplemental Update.

You better BACK UP your Macbook Pro FIRST if you are going to attempt this upgrade.

Said to improve installer robustness.
So they changed the installer.

Looks like they BROKE or borked the installer for my old 2011
macbook Pro 17″

The only way I saved my a** was to boot with COMMAND R
and then Diskmanager
and then FIRST aid on the boot disk.

First Aid looks to have then taken the restore image
and over wrote the changes done by this destructive
supplemental patch.

The patch looks to be very sensitive to EFI and what model you are using.

I am just going to WAIT for the new major High Sierra update to be released.

That will contain this update plus other fixes.

Impact: A local attacker may gain access to an encrypted APFS volume

  1. You might be able to fix your old 2011 macbook pro. You can put in a new battery yourself. Same for a hard disk. Sometimes the memory slots get messed up. So just try to run it on ONE memory stick. Try one slot then the other. Might bring your mac back to life. Try a PRAM reset by holding down Option+command + P+R when powering it on. This is kind hard.
    lastly, the 15" Macbook with the USB-C charger is OK. But the keyboard is all new. If you get any small crumbs into the keyboard it gets screwed up on the new Macs.
    You might want to try to get a 2015 macbook pro.
