21216	Recovery Mode is not Accessible in Newer MacOS Guests	Mac OS X	VirtualBox-7.0.2	2022-10-29T17:34:03Z	2022-10-29T17:34:03Z	2022-10-29T17:34:03Z	"IF you install Monterey on VirtualBox, you're not able to boot into Recovery Mode via the VB BIOS (e.g. ""Boot from file"") because there's no boot.efi file shown under the GUID in the Recovery Mode partition.  This issue appears to have started with BIg Sur.  If you access the filesystem with the UEFI Shell, you'll see that there are a bunch of files names boot.efi.<some string> in that partition, but this new naming system is obviously not recognized by VirtualBox.

This problem reproduces with the latest VirtualBox, VB 7."	ThomasF

20543	macOS Guest Additions do not include mount.vboxsf	Mac OS X	VirtualBox 6.1.26	2021-09-11T17:47:16Z	2021-09-13T10:47:16Z	2021-09-13T10:47:16Z	"When successfully installing the Darwin guest additions, the mount.vboxsf tool is not included, while there is a source tree available and seemingly being built.

Steps to reproduce:
- Disable all security on macOS Catalina guest
- Insert the Guest Additions ISO
- Install Guest Additions
- `mount -t vboxsf VboxShared /Users/Shared/Host` result in a File Not Found error because /Library/Filesystems/vboxsf.fs does not exist

I also checked the contents of the .pkg and as far as I can tell, it does not contain any tools for mounting file systems. The source tree on the other hand does contain some kind of implementation in src/Vbox/Additions/darwin/VboxSF, which I unfortunately can't seem to manage to build because the build system does not seem to be compatible with Xcode 12.

As for some context:
I am trying to set up a macOS Catalina build system to build Unreal Engine games on a Big Sur (and Windows) host. The VM should have a minimally sized main disk and should share the actual build tree with the host. I already have all this set up, using SMBFS to share the build tree and it is working ok, but network performance is only about 30MB/s, so builds take forever.

Therefore I am trying to mount shared folders in the macOS 10.15 Catalina guest in hopes they will give me better performance, somewhere in the range of the 400MB/s, the virtual disk in the VM provides. I already installed the guest additions successfully, but as far as I can see, they are missing the mount.vboxsf tool to actually mount the shared folders. I also tried to unpack the VboxDarwinAdditions.pkg, contained on the additions iso of multiple VirtualBox version, but the tool simply isn't there and is not being created. As per the source tree, there should be a tool available to mount the shared folders though, so I am guessing this is a bug in the build environment.

17313	Feature: Keyboard scancode translation	other	VirtualBox 5.1.30	2017-11-26T06:16:09Z	2017-11-26T06:16:09Z	2017-11-26T06:16:09Z	"Most modern keyboards use IBM scancodes, and so VirtualBox users are likely to get fairly consistent behavior when sending these scancodes to just about every VM, via VBoxManage controlvm <vm> keyboardputscancode <hexpair>... However, macOS guest VM's use a different scancode set, one for Apple keyboards. This does not present a problem for most graphical VirtualBox users, however it does break some things for command line driven systems such as packer.io. In particular, systems like packer that are built on top of VirtualBox and want to send key codes to macOS VM's are faced with the nuisance of performing scancode translation. I propose that VirtualBox offer a VM configuration option like:

VBoxManage modifyvm <VM> --fromscancodes ibm --toscancodes apple

or similar flag syntax, that declares that VirtualBox should automatically remap scancodes sent via VBoxManage controlvm <VM> keyboardputscancode <hexpair>..., relieving packer and other tools from having to worry about such low level details (packer could then simply use IBM scancodes all the time).

I've also filed a ticket with packer to select more appropriate scancode sets for different kinds of VM's:

https://github.com/hashicorp/packer/issues/5635

As a mac user, I really don't care which of these is implemented, I just want to be able to use macOS guest VM's without having to hack around keyboard incompatibility issues!"	mcandre
16847	Incomplete DMG support	Mac OS X	VirtualBox 5.1.22	2017-06-19T08:56:04Z	2017-06-19T08:56:04Z	2017-06-19T08:56:04Z	"Some DMG cannot be mounted in a VM with a ""`VERR_VD_DMG_INVALID_HEADER`"" error.

* [http://adcdownload.apple.com/Developer_Tools/Xcode_7.3.1/Xcode_7.3.1.dmg Xcode 7.3.1], that's actually the weirdest. The VM (OSX) shows a ""`The disk you inserted was not readable by this computer. Ignore | Eject`"". If you copy the same exactly DMG in the VM, it is mounted and works as expected.

9390	Mac OS X guest video memory remains on 4MB. It does not use the video memory setting of the guest configuration.	Mac OS X	VirtualBox 4.1.0	2011-08-06T09:12:58Z	2015-09-10T02:57:35Z	2015-09-10T02:57:35Z	It does not matter what setting you choose for video memory (0 - 128 MB) for a Mac OS X server guest. The guest OS always reports that there is only 4MB screen memory available. Please see my attached screen shots for the guest Os report. This is evident when trying to use screen share to the guest OS. The screen share quality is in very low. This also could be the cause of the jerky graphics inside the guest OS normal operation eg. the menu navigation. 	Pieter
