I want to transfer my vault to a new HD. The new has been formatted for Mac. Update Vault path is grayed out, despite doing all the correct steps beforehand

Question

I have followed directions to transfer my vault to a new HD. It is grayed out, despite doing all requisite steps beforehand. If I get 'info' on Aperture the lock icon shows and I cannot change it to unlock.

I think you may be getting confused by the 'Lock'.
The vault is locked in the files system to prevent accidental deletion.
The reason the 'Update Vault Path' is greyed out is because it is still detecting the original vault on your system.
Here's a simpler process.
Restart your system (Aperture may still have a reference to the vault and this will clear it).
Make sure you have copied the vault to the new location.
Move the vault to trash. It will warn you the file is locked. Continue to move it anyway.
Empty your system trash.  It will warn you the trash has locked files. Continue to empty anyway.
Now the old vault is gone from your system, in Aperture, the vault will show as disconnected and you can update the vault path:
You can then Navigate to the new location:
And the vault will reconnect and show the available storage of the new drive:
I suspect you are following advice about trying to remove the lock. But this is not necessary, the lock means you'll simply get warnings when deleting (assuming you have permissions to delete), but you can jsut override these warnings. If at any stage you get an error saying the file is in use, just reboot and retry that stage.
