I want to hide the about tag in rEFInd. So, I did according to the info in config and website, which is to add a showtools line with no options.

And, nothing happens. I still see About, Shutdown, Reboot, Firmware tools in the rEFInd screen

# Default is shell,memtest,gdisk,apple_recovery,windows_recovery,mok_tool,about,hidden_tags,shutdown,reboot,firmware,fwupdate
# To completely disable scanning for all tools, provide a showtools line
# with no options.
#
#showtools shell, bootorder, gdisk, memtest, mok_tool, apple_recovery, windows_recovery, about, hidden_tags, reboot, exit, firmware, fwupdate
showtools

Eventhough the previous showtools line is a just a comment, I removed it too. And still nothing happens.

Does anybody have any idea?

I only want Shutdown, Reboot.
