laugao Posted November 14, 2009 Share Posted November 14, 2009 I have read many guide with a exist leopard system to snow leopard But I heard that many people install the snow leopard directly from WIN7/XP That really save a lot of time. So I am planning to do the same thing But no matter I use boothink or the Chameleon, the installation cannot be started and it stopped after a white Apple sreen then suddenly the monitor lost the signal....it went black I tried to put the 260+ Efi String to the computer.boot.plist, or put necessary KEXT to the Extra/Extensions And there is no change My board is EP45-UD3, Rev. 1.1, MSI GTX 260+ OC version Looking for somebody's help!

dgobe Posted November 14, 2009 Share Posted November 14, 2009 Have you tried removing the EFI string and using <key>GraphicsEnabler</key> <string>y</string> in /Extra/com.apple.Boot.plist? Use this "boot" file in conjunction with Chameleon. http://netkas.org/?p=271 Install Chameleon, download above "boot" file, copy "boot" to the root of your drive.
