  • For High Sierra you should use either a current Clover-Version beginning with 4173, better 4220.
    Also use the newest Clover Configurator 4.52.0.0 in which you can create the newest SMBIOS combinations, which also contain values for "Firmware Features", "Firmware Feature Mask" and the newest "BIOS Version"-numbers and "Bios Release Dates".


    Those values can also be added to a defaults.plist file for your Ozmosis-based System.
    This file should be placed on the hidden EFI-partition under /EFI/Oz.
    Any changes made in there must be activated by doing an NVRAM-Reset, by using the following keyboard shortcuts while in BIOS, Boot menu or in Ozmosis menu:
    Alt+WinLogo+P+R


    All the folks still forget to create their own defaults.plist instead of using the one within the Ozmosis-ROM.
    With all the different possible hardware setups and combinations, the usage of a dedicated defaults.plist is mandatory.

    Zitat

    Also use the newest Clover Configurator 4.52.0.0 in which you can create the newest SMBIOS combinations, which also contain values for "Firmware Features", "Firmware Feature Mask" and the newest "BIOS Version"-numbers and "Bios Release Dates".


    i have created my usb stick , start the installation with Clover r4084
    the first boot i start with my usbstick , on the second reboot external and it start the installation with 25 min remaing
    but it stops with error verifying firmware
    is there a tutorial easy to read or wath how to install it?

  • In regards to your Defaults.plist the extraction via MMTool oder UEFITool sometimes breaks the XML-format which leads to the mentioned issue with PListEdit Pro.
    Just use another Editor like TextMate, which has Syntax Highlighting to help you find the corrupt lines which prevent PlistEdit Pro to load the file correctly.

  • Use the following Tool to extract your current Defaults.plist on your Desktop:
    Auslesen der Ozmosis-Parameter
    Use the first button in the "Export Section" on the right sight of the app window.
    It will create a folder called "Ozmosis" on your Desktop in which you'll find the extracted file called Defaults_"current_time".plist.
