Change MacOS X Guest Screen Resolution for VirtualBox

Question

I tried all the alternatives and resources that I found on the Internet to achieve a change in screen resolution in my MacOS X guest. I have the latest version of VirtualBox (4.1.22) and I have MacOS X 10.6.3 Snow Leopard running in the guest guest vm system.

Some solutions that do not work for me:

• Configure virtual machine settings:

Add and run these two commands in the .vbox file:

vboxmanage setextradata "MAC OS X" "CustomVideoMode1" "1360x768x32" vboxmanage setextradata "MAC OS X" "GUI/CustomVideoMode1" "1360x768x32" 

• Changing the guest OS boot configuration:

Modify / Library / Preferences / SystemConfiguration / com.apple.boot.plist with these lines:

 <key>Kernel Flags</key> <string>"Graphics Mode"="1360x768x32"</string> <key>Graphics Mode</key> <string>1360x768x32</string> 

Any other suggestion that I missed.

Thanks in advance,

Answer 1

I fight too. I saw the third option mentioned in some places : in addition to CustomVideoMode1 there is a parameter VBoxInternal2/EfiGopMode , which can be set to one of six fixed permissions:

VBoxManage setextradata "vmname" VBoxInternal2/EfiGopMode 3

Possible values ​​for EfiGopMode:

 0: 640x480 1: 800x600 2: 1024x768 3: 1280x1024 4: 1440x900 5: 1920x1200 

I have not tried this method myself yet, because I want to go to 1600x1200 ...
