It took me a while, but now 10.13 works fine on my hack. I did an update from 10.12.6 to 10.13. First thing to do: 1) Update Clover Bootloader to the latest version. Put the KEXT Files in Others 2) Make sure, you drop MATS in config.plist. Otherwise it won't work at all. Code (Text): <key>DropTables</key> <array> <dict> <key>Signature</key> <string>MATS</string> </dict> </array> 3) Update the BIOS in config.plist. Use Clover Configurator and choose your model, put in your old SN# and save the file. Reboot. 4) Start the installations by skipping APFS. Code (Text): /Applications/"Install macOS High Sierra.app"/Contents/Resources/startosinstall --converttoapfs NO --agreetolicense 5) Now the update process should work without any issue 6) After 10.13 comes up, just update the NVIDIA Web drivers. Hope it helps!
