Virtualbox Drivers For Mac

Introduction to Guest Additions. As mentioned in Section 1.2, “Some Terminology”, the Guest. In this step by step video tutorial i will show you how to install graphic and all the other drivers on your virtual operating system from oracle vm virtualb. Technically, Oracle VM VirtualBox implements 3D acceleration by installing an additional hardware 3D driver inside the guest when the Guest Additions are installed. This driver acts as a hardware 3D driver and reports to the guest operating system that the virtual hardware is. For the various versions of Linux that are supported as host operating systems, see.

EDIT: Added installer package for easier installation.

Put this together after setting up an OS X guest in VirtualBox and thought i'd share with the community.
This driver supports both Leopard and Snow Leopard guests
(Please note this driver is for 32-bit mode only)High
To install, download and run package in guest, reboot and enjoy sound!

To Install manual way (Simplified for those who aren't familiar with kext loading):

You can use Kext Helper to install if you don't want to use the terminal: http://cheetha.nethttp://web.mac.com/v1.42ghz/Kext_Helper/Software_files/Kext%20Helper%20b7.zipFree
It's recommended to delete Extensions.mkext after still to ensure the new kext gets loaded.
Terminal method:
1.Extract the zip to your guest OS X desktop (not into a folder, literally to your desktop) this means there should be a file on your desktop called AppleAC97Audio.kext?
2. Open Terminal, (/applications/utilities/terminal.app)?
3. Type sudo -s in terminal then your admin password following this, now you should be root.?
4. Type sudo mv /users/(YOUR USERNAME)/desktop/AppleAC97Audio.kext /system/library/extensions ?
at this point the file AppleAC97Audio.kext should have disappeared from the desktop,?
Virtualbox5. Type sudo chmod -R 755 /System/Library/Extensions/AppleAC97Audio.kext
?6. Type sudo chown -R root:wheel /System/Library/Extensions/AppleAC97Audio.kext?
7. Now, CLOSE TERMINAL ?then go to /system/library/caches/com.apple.kext.caches/ and trash? Extensions.mkext
(This cache will regenerate automatically on boot with the current kext library)

8. Reboot and enjoy sound support!
Anyone looking to build these drivers see the source here: http://www.opensource.apple.com/source/AppleAC97Audio/AppleAC97Audio-5/
UPDATE: x86-64 source with VirtualBox tweaks here:
AppleAC97Audio-5-x86-64_sources.zip
AppleAC97Audio x86-64 source with VirtualBox tweaks, needs work for proper sound quality.

Note: This is just the source and requires XCode to compile, theres some issues with the audio quality that came with the 64-bit port that I haven't the time to track down so i'm putting it up to the community and the VirtualBox devs to take a crack at it, the important thing is this source is full 32/62-bit compliant.
