Virtualbox has the option for a MacOS virtual machine in it’s New VM dialog, but we will need to make further adjustments to make it truly Mac-ready. Pop open Virtualbox, and Create a new Virtual Machine. Name this MacOS Mojave, and set it to Mac OS X (64-bit). Os x 10.6 snow leopard. Locate the vdi file in your desktop file manager or from the command line, and relocate it to the new disk. Go back to the VirtualBox main window, select the virtual machine (in the case of my. Follow the steps below to create a new virtual machine for macOS Mojave using the ISO file. Open up your VirtualBox application and click New; Click Expert Mode and select the following options then click Create. Type a suitable Virtual Machine Name. Virtual Machine Location (a separate drive is recommended). Type (Mac OS X).

guest(s) are earlier versions of OSX (I use the Box installations for testing GCC toolchain builds across the OSX range).
Monitoring I see around 1Gb / hour kernel memory leakage (wired) which eventually results in spontaneous quits of GUI programs and a kernel panic. The panic is from some random process (whatever happens to make the request that exceeds the resource) - so there's nothing helpful in terms of a VB backtrace (nor is there anything useful in the visible allocations for the VB guests - those don't change after the initial ramp up).
Of course, this could be a virtualisation framework bug in 10.15 * the same setups work fine on 10.14 and 10.13. *
Any ideas / known issue / workaround?Host device : MacBook Pro 13inch 2017 model, 8Gb RAM, Core i5 CPU

I am getting very slow performance on this guest, when moving windows it stutters. When playing short MP4 videos in VLC, the app goes non-responsive and is incredibly slow to respond to input.
The relevant VM settings are :-
Video RAM : 128Mg

Virtualbox Mac Download

Acceleration > Virtualization : Default
Hardware virtualization : Enabled nested paging (no other option appears here)
As a point of comparison, my rather old Windows 10 PC (Core i5 3450 Ivy Bridge @ 3.10Ghz, 8Gb RAM) runs the same guest OS much better and faster.
The only difference I can see in the VM options it that my PC has the additional option of 'VT-x AMD-V' Hardware virtualization.
Can anyone advise?
Are MacBook Pros just not great for VirtualBox?
