With "Save on Shutdown" for RAM disk, even erasing and unselecting the option and deleting the file in Preferences folder, system continues to save on shutdown and turn option on.
Only way out was to turn RAM disk off, reboot and this time turn on w/o the option (which was greyed out and turned on by default - though I am sure that before it was off by default).
Is that option set with MacOS Preferences file, with the RAM disk (even after an erase etc it continued to stay in effect) or an invisible file? Won't let user change their mind and disable w/o removing the ram disk.
Is this a "safety" feature? If so, turning off "Save on Shutdown" ought to put up "Are you sure?" alert when changed. - Greg
