How to increase screen resolution in VirtualBox?

Question

virtual box

I rolled my interest for the sake of Mac OS Sierra on a virtual machine. The only problem is that I can't change the screen resolution from ridiculous 1024x768. Googled commands

VBoxManage setextradata "MacOS" VBoxInternal2/EfiGopMode 4

and

VBoxManage setextradata "MacOS" VBoxInternal2/EfiHorizontalResolution 1440
VBoxManage setextradata "MacOS" VBoxInternal2/EfiVerticalResolution 900

didn't help. Another instruction advises editing the org.Chameleon.boot.plist file in the Extra directory, but I don't have such a directory. Save-help!

Answer 1

Close VirtualBox before running commands.
Open a command prompt and type
For windows:

cd "ваш/путь/к/virtualbox"
VBoxManage.exe setextradata "Your VM name" VBoxInternal2/EfiGraphicsResolution 1440x900 (или 1920x1080, и т.д.)

For Linux:

VBoxManage setextradata "Your VM name" VBoxInternal2/EfiGraphicsResolution 1440x900

Start your virtual machine.

Answer 2

Values ​​can be added to the config:
Where N is a number between 0 and 5, representing resolutions: 640x480, 800x600, 1024x768, 1280x1024, 1440x900, 1900*1200 respectively.

Answer 3

I tried everything too. I demolished virtual box twice and did this for the third time.
I went to the directory: C:\Users\tsyts.PC\.VirtualBox\
(pay attention, there is a folder .VirtualBox and VirtualBox , with and without a dot)
In the folder with a dot there were two files with the same name, but a different extension: VirtualBox. xml and VirtualBox.xml-prev
I opened both files with a text editor and in each, under all of them, I inserted that line:
I did this in both files. This should be done only with the virtual box closed, it's better to even restart the computer and immediately go to the folder and add a line to these files. Only then, as saved the changes, try to run.
Initially, I tried to put 5 and it didn’t work for me, the permission didn’t change, then I tried to google and THIS ARTICLE says that the numbers are from 0 to 4, and there are no more permissions, so try it. Good luck

I will write here so that it does not disappear - suddenly someone needs it.
After VB hung up, Windows suddenly began to display 1920x1200 instead of 1920x1200 in full screen, for no reason at all, 1920x1136 or something like that - black stripes of about five millimeters above and below. What only dances with a tambourine I did not perform! Rearranged VBoxGuestAdditions, rules for the properties of the machine, changed firewood for the display - nothing helped.
The following sequence of actions helped:
- Host-Home, View, disable full screen mode - the machine will be displayed in the window
- Host-Home, View, Virtual Screen 1, a menu will appear with the items "Request permission ..." (these items do not appear in the mode full screen!), select the desired resolution.
- Make sure inside the machine that the desired resolution has appeared, switch to it
- Host-F to go to full screen
UV. I thought that I would have to demolish the car and rebuild ...
