Another approach I took was refusing the premise we even need OS X boot entries in GRUB, so why not just disable os-prober on Macs, and then the four broken OS X options won't even appear. Instead the user can use the built-in firmware boot manager to boot either Fedora or OS X
. Maybe there's some legitimate concern some users won't know how to activate this boot manager using the option key at the startup chime
? This RFE was likewise proposed a while ago, changed to something else, neither proposal going forward, and then being close without action.
