Hi,







I followed this macbreaker guide to install OS X 10.8 on VirtualBox, on my win7 64bit machine. Everything was successful, and I even got sound working. However, I still see the following problems:







1. In full screen, my display is 1152x864, even though the native screen is 1600x900.



2. If I click on launchpad, the system freezes up for about 30 seconds, and nothing happens.



3. If I open a new tab in Safari, the default screen with the black curved surface where you can select recent pages flashes constantly.







Per the linked article step 7, I tried doing:









Code:







>vboxmanage setextradata "Mac108" "CustomVideoMode1" "1600x900x32"



VBoxManage.exe: error: Failed to create the VirtualBox object!



VBoxManage.exe: error: Code CO_E_SERVER_EXEC_FAILURE (0x80080005) - Server execu



tion failed (extended info not available)



VBoxManage.exe: error: Most likely, the VirtualBox COM server is not running or



failed to start.






As you can see, the command does not appear to work.







Researching possible solutions, I found this superuser thread. And I noticed that in the file on my ML Guest system "/Extra/org.chameleon.Boot.plist", I have these entries:









Code:







<key>Graphics Mode</key>



<string>1600x900x32</string>






which seem to suggest that the correct setting is already there, but again it does not actually work.







Thanks very much for any help!
