VIRTUAL BOX 6.1 LINK PARALLEL DEKSTOP 15 FOR MAC

VirtualBox is a family of powerful x86 virtualization products for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software under the terms of the GNU General Public License (GPL). Presently, VirtualBox runs on Windows, Linux and Mac hosts and supports a large number of guest operating systems including but not limited to Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7, Windows 8, Windows 10), DOS/Windows 3.x, Linux (2.4, 2.6, 3.x and 4.x), Solaris and OpenSolaris, OS/2, and OpenBSD. VirtualBox is being actively developed with frequent releases and has an ever growing list of features, supported guest operating systems and platforms it runs on. VirtualBox is a community effort backed by a dedicated company: everyone is encouraged to contribute while innotek ensures the product always meets professional quality criteria.

Features of VirtualBox 6.1 for Mac

General:

Implemented support for importing a virtual machine from Oracle Cloud Infrastructure
Extended support for exporting a virtual machine to Oracle Cloud Infrastructure, allowing the creation of multiple virtual machines without re-uploading. Also added option to export a VM to the cloud using the more efficient variant "paravirtialized", and to specify free-form tags for cloud images
Virtualization core: Support for nested hardware-virtualization on Intel CPUs (starting with 5th generation Core i, codename Broadwell), so far tested only with guest running VirtualBox
Graphics: New style 3D support (with VBoxSVGA and VMSVGA) remains, old style 3D support (with VBoxVGA) has been completely removed
Shared Clipboard: Implemented experimental support for file transfers (Windows hosts/guests only at the moment). Needs to be enabled via VBoxManage (disabled by default). In addition, the following items were fixed and/or added:
Virtualization core: Drop recompiler, i.e. running VMs now needs a CPU supporting hardware virtualization
Runtime: Works now on hosts with many CPUs (limit now 1024)
Appliance and Cloud Import: Add field for defining firmware type (not part of OVF spec and thus manual in the Appliance case, for OCI it is automatically taken from the instance information)
Input: Added support for horizontal scrolling in the PS/2 mouse device using the IntelliMouse Explorer protocol. Note that this support is automatically used by Linux guests but not by Windows guests
PCnet-ISA: Added new network adapter type, currently CLI only
Audio: Allow changing the host audio backend while the VM is in saved state
ACPI: Report NVMe controller
VGA: Improve hardware and BIOS compatibility
VMSVGA 3D: Fixed OpenGL compressed textures
Guest Control/VBoxManage: Added support for specifying multiple sources when renaming guest files
API: Reduce the amount of leftovers from Move VM function
Shared Clipboard: Implemented experimental support for file transfers for Linux hosts on Windows guests (disabled by default)
VBoxSDL frontend: Fixed running on Windows hosts
Windows guest: DXVA implementation for WDDM driver
Documentation: Updated supported host operating systems, added few new manual pages (more to come later) macOS host: Fix VM crashes (most visible on macOS Catalina)
Loads of effects and themes for various photo industries

GUI:

Improved the VISO creation and file manager dialogs
Virtual machine list of VirtualBox Manager was improved. Machine groups are now more obvious visually and VM search functionality has been improved. Global Tools element can now be pinned in place, to avoid scrolling it with rest of machine list
Virtual machine details pane is now extended with embedded editors for selected VM attributes, allowing user to edit them on-the-fly byi clicking corresponding hyper-links without opening VM settings dialog
Details pane provides more complete information
Internal medium enumeration routines were optimized to reduce the load and optimize the performance in cases when user have lots of media registered. Also, we again allowed to add existing media (and create new) via Virtual Media Manager
More consistent medium selection (both showing known images and allowing to select using the file picker)
VM storage settings page was adjusted a bit in usability regard. User is now allowed to change controller bus type and can move attachments between the controllers by using drag and drop
Storage and Network settings pages bug-fixes and usability optimization
Added a new soft (virtual) keyboard enabling arbitrary keyboard input to guests, including multimedia keys
Fixed crash in cloud related wizards when accessibility functionality was enabled
Show VM CPU load as part of status bar CPU indicator
Improved and extended the Session Information dialog
Fixed/improved mouse pointer scaling
Some issues related to mouse integration cursor scaling were addressed (bug #14366), more to go
Fix and unify geometry save/restore in various dialogs
Added the missing restriction options for disabling new functionality such as the VISO creator
Popup messages mouse click fix
Loads of effects and themes for various photo industries

Graphics:

Remove 3D support for VBoxVGA (old one deprecated with 6.0)
Additional texture format support on Windows host
Improved fix for flickering on Windows host

vboximg-mount:

Experimental support for direct read-only access to NTFS, FAT and ext2/3/4 filesystems inside a disk image without the need for support on the host
Now also available on Linux host

Storage:

Experimental support for virtio-scsi, for both hard disks and optical drives (including boot support in BIOS)
For optical drive emulation fix empty host drive crash

USB:

Improvements for EHCI controller implementation
Filter can now specify port path, uniquely identifying a port in a system

NAT:

Fix TFTP OACK response, send only if request has options

NAT Network:

Use non-blocking sockets on Linux for accepted incoming connections (port forwarding)

VBoxSVGA/VMSVGA:

Support YUV2 and related texture formats with hosts using OpenGL (macOS and Linux), which accelerates video playback when 3D is enabled by delegating the color space conversion to the host GPU
Several drawing fixes for the 3D case

VBoxManage:

More cloud functionality coverage, e.g. starting a cloud instance
As part of the guest control feature support moving multiple source files/directories to a target directory
Show "unrestricted guest" and "nested HW virtualization" CPU features when listing the host information

SMBIOS:

Store system UUID in little endian format which is the default for new VMs, while existing VMs stick to the old VirtualBox behavior of storing them in big endian format for backwards compatibility to avoid breaking the activation status of Windows VMs

Windows Guest Additions:

Many fixes for drawing problems in the driver for VBoxSVGA
Fixes for legacy VBoxVGA adapter, restore previously working cases
Restore VHWA functionality for VBoxSVGA

EFI:

Switch to newer firmware code base and add NVRAM support, should improve compatibility with OSes significantly
Added support for booting from APFS
Added support for non-standard SATA and NVMe boot device paths created by OS X
Modified updated EFI code base to support older OS X guests again
