Are you running Snow Leopard on Intel or AMD Computers by any of the
desktop virtualization software VMware or VirtualBox? Then this post
will be helpful to increase screen resolution size of Snow Leopard
Virtual Machine to get full screen. Adjusting screen size including wide
screen on VMware is easy since VMware tools ( Not official, with VGA
driver) available, but setting up screen resolution in VirtualBox
is slightly different for each installation methods.
Updated on 21 Aug 2010
This post is updated with most of the working methods on VirtualBox to adjust screen size with user comments and my experience.
VMware users
If you are running latest Snow leopard on VMware by any of the following methods,
Install Mac Snow Leopard 10.6.4 in VMware Player with Pre Installed Mac VMware Image
Fresh Snow Leopard 10.6.4 installation on VMware with Original retail DVD
Then visit
Increase Screen Resolution with Wide Screen
support for Mac OS X on VMware
VirtualBox Users
If you are running latest snow leopard on VirtualBox with following any of the methods,
How Install Mac Snow Leopard on VirtualBox 3.2 in Non Apple, Intel PC
Mac OS X Guest Snow Leopard
10.6.4
on PC with VirtualBox 3.2.6
Then follow the steps,
Method -1
If
you installed Mac OS X by any of the hacked (hackintosh) ISO files,
then do this first. ( This works for original retail DVD installations
also)
You could see com.apple.Boot.plist file in /Extra
folder. Before continue the next steps, first edit this file under
/Extra with mentioned strings in step 3.
This may give the required resolution without editing the file under /Library/Preferences.
If this doesn’t work then modify c
om.apple.Boot.plist
under /Library/Preferences as shown below
Increase Mac OS X Snow Leopard Virtual Machine Screen Resolution in VirtualBox
1) Start the Virtual Machine.
2) Open /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
in Text editor.
3) Type
<key>Graphics Mode</key>
<string>1280x1024x32</string>
1280x1024x32
– is your option. Type the correct screen resolution which matches your monitor.
Here is the screenshot of my file.
4) Select Save As in Text editor file menu and save it on desktop or somewhere else.
Make sure to save with same .plist
file. ( Remove the tick as mention below)
5) Now, copy or drag com.apple.Boot.plist
file from desktop to /Library/Preferences/SystemConfiguration/
or /Extra
location where ever it needs to be replaced.
Enter Mac root (admin) password to authenticate replacing file.
6)
That’s it. Restart the Mac Virtual machine. By default Mac OS X will go
to the screen resolution you set up com.apple.Boot.plist. Check it by
going to ‘Display’ under ‘System preferences’.
I didn’t invent this; I just illustrated which mentioned here.
Method -2
Try this method if method 1 fails.
This method to modify VirtualBox settings for specific virtual machine.
Close VirtualBox completely and run following command,
VBoxManage setextradata “VM name” “CustomVideoMode1″ “1280×800×32”
“VM name” –
Excact virtual machine name of Mac OS X, execute this command with Quotes.
Make sure VBoxManage command added to Windows path or you are running it from VB working folder.
The above command will modify XML file of Virtual machine. Just boot and see whether its working.
If not, while booting at the EFI boot loader screen, type;
“Graphics Mode”=”1280x800x32”
and press Enter.
Always better to give the same screen resolution size mentioned in com.apple.Boot.plist file.
Method -3
This is similar to method 2, but slighlty different.
Execute this command in VirtualBox folder:
VBoxManage setextradata “VM name
” VBoxInternal2/EfiGopMode 3
“VM name” –
Excact virtual machine name of Mac OS X, execute this command with Quotes.
No 3 –
this is the number of video modes. Only 5 resolutions are supported:
0 – 640×480
1 – 800×600
2 – 1024×768
3 – 1280×1024
4 – 1440×900
Or you can add a string on Virtual machine’s XML file to execute this command every time while machine is coming up.
<ExtraDataItem name=”VBoxInternal2/EfiGopMode” value=”3″>
Warning –
If you are copying any of the commands from this post, make sure opening and closing quotes are correct!!
I’m
sure one of this will work with VirtualBox to increase Snow Leopard
screen resolution. Special thanks to Sysprobs readers who
left valuable comments.
Share your success and failure stories on this method.We will fix it together.
Have fun
