This option relies on a poorly documented (or rather undocumented) RTC memory access, and unspecified RTC memory layout, which is implementation-specific. To workaround this issue a new option enabling RTC memory erase upon waking from hibernation was added:īoot > RtcHibernateAware = YES (BOOLEAN, off by default) More details could be found in this message. However, the graphics output protocol is not in anyway modified so if the OS draws after it is started then it is after the boot screen is drawn and will overwrite the custom logo, at least for now.Ī data leak issue was identified in the hibernation code, allowing hibernation encryption key to be passed to the system through RTC and preserved till the next hibernation without a subsequent erase. The CustomLogo key can also be used under GUI/Custom/Entries in conjunction with BootBgColor for a different screen for every OS. If no option is specified then the boot screen will be drawn only for >= 10.10 Yosemite, so it remains compatible with previous behavior. - A base64 encoded PNG, BMP, or ICNS data.Path - A file path to load a custom image from.None - Use no logo only background color, gray if not specified by custom entry.Theme - Use the theme boot screen for entry type - NOT IMPLEMENTED.Alternate - Use the alternate white on black apple logo.Apple - Use the default gray on gray apple logo.true - Uses the default boot style, Apple.OR OR Apple/Alternate/Theme/None/Path OR PNG/BMP/ICNS base64 dataĮnable the drawing of the custom boot logo.
