Here's what I did:

A. ALTER THE FILE com.apple.Boot.plist in /Extras

1. Opened Finder. On the left side opened the primary harddisk (the first device where OSX is installed)
2. Went to /Extras/
3. Copied the com.apple.Boot.plist to the desktop
4. Opened com.apple.Boot.plist with TextEdit.
5. Added
Code: Select all   Expand viewCollapse view
<dict>
    <key>Graphics Mode</key>
    <string>"Graphics Mode"="1680x1050x32"</string>
    [...]

6. Save As
-> Save as: com.apple.Boot.plist
-> Plain Text Encoding: Unicode (UTF-8)
-> Turn off... use ".txt"

7. Drag an Drop the file back into the /Extras folder
8. Autenticate with your password

B. NOW DO THE SAME IN THE FOLDER "/Library/Preferences/SystemConfiguration/"

C. Shutdown the virtual Machine

D. Close ALL VirtualBox Instances

E. Edit the file PATH_TO_VIRTUALBOX_FOLDER/Machines/OSX/OSX.xml
OSX.xml is the file if your virtual machine is named "OSX", so it could differ from your installation.
Add the following line:
Code: Select all   Expand viewCollapse view
   [...]
   <ExtraData>
      <ExtraDataItem name="CustomVideoMode1" value="1680x1050x32" />
     [...]


F. Start VirtualBox and your virtual machine
Enjoy your new resolution :D


I didn't find the folder /Extras on my System...:(

"/Library/Preferences/SystemConfiguration/" here you'll find the boot.plist. (although none of these methods worked for me at a laptop 1366x768)

I was also trying to get 1366x768x32 at my laptop without sucess...

After looking at the ?video options, I found out that "Graphics mode"="1368x768x32" is the right option (same goes for the VB XML file) =)

How did you manage to get on the ?video command boot 1366x768x32? I get a lot of them but not that one. In vmware i get it, but the overall emulation is mediocre.

Pm me if you care to explain, thanks :)

Hi,

I'm a little desperate about gettng OSX to run fullscreen in virtualbox on my laptop.

Here is my setup:

I'm running Virtualox 3.2.10 r66523
I managed to install OSX 10.6 from a retail DVD using empireEFIv1085.iso as a loader.
Everything is workng just fine, but i can't manage to change the resolution at all.

I tried a ton of settings n the last few days, but whatever I do, it keeps showing in the original 1024x768 resolution.

I can edit the boot.plist file inside OSX withouy any problem, but no matter what I set there, it's like it's never actually used. I don't have any extra folder (probably because I didnt use any hacked version, only retail dvd image).

I tried many Graphics Mode syntax in the plist file :

<string>"Graphics Mode"="1920x1080x32"</string>

<key>Graphics Mode</key>
<string>"Graphics Mode"="1920x1080x32"</string>

<key>Graphics Mode</key>
<string>1920*1080x32"</string>

<key>Graphics Mode</key>
<string>1920x1080x32"</string>

I'm assuming the last one should be correct, but none works.

I also tried all those combinations with the matching extradata in the virtualbox xml:

<ExtraDataItem name="CustomVideoMode1" value="1920x1080x32"/>

I even tried this extradata:

<ExtraDataItem name="VBoxInternal2/EfiGopMode" value="60"/>

Which is supposed to affect the resolution too, but again, no luck.

I'm beginning to think that this has something to do with my EFI loader. I'm using EmpireEFI because it was the one provided by the installation tutorial I used, but maybe it is preventing the resolution change.

What loader are you guys using? Or do you even have to use one? If I try to boot OSX directly, it doesnt work, but maybe there is something I am missing.

As a side note, I was able to make it work usng vmware, because there are some "guest additions" available for OSX in vmware, but I would really like to have it working in virtalbox.

Any help would be greatly appreciated,

thanks!

Magimat, from what I understand is that you're not running this on a genuine Mac, but on a PC using some hacks. This is not supported by VB and considered illegal. Please see Important notice regarding Mac OS X as Guest.
