How to Enter Full-Screen Mode on macOS Catalina on VirtualBox on Windows PC? Let us know the result, It is worthy of sharing because knowledge is all about sharing and helping. As I said before I have not tested this method on Linux, Debian, Fedora, and other Linux Distribution, so, if anyone has tested. So, if anyone tests it on Kali Linux, please let us know the result. Also, keep in mind, it can work with Ubuntu too but I’m not pretty sure about the Linux itself. This Method works with macOS 10.15 Catalina, macOS 10.14 Mojave, and older versions until the Mac OS X Yosemite. What I mean by fixed aspect ratio, It means with HD, Full HD, 2K, 4K, 5K, and even the 8K. There is an alternative method which can be used to fix or enter Full-Screen Mode, but the truth is, it can only work with the fixed aspect Ratio version. They are also saying when the Virtual Machine is centered on the Desktop 3 Pixels remains from either site, and it shows black color. Users on Ubuntu have tested and applied different methods, they were able to bring the resolution to 1360 x 768 Pixels without installing additional modules. The truth is, VirtualBox cannot support the exact 1366 x 768-pixel resolution, I don’t know why but still users are complaining from it. The only downside to this is that lower end computers might have performance issues, but if you have enough RAM and CPU to go around this is quite the groovy setup.You may be encountered with the screen resolution problem on VirtualBox on Windows while using macOS 10.15 Catalina, Linux, Ubuntu, Debian, Fedora & Linux Distribution. Now you have your Ubuntu (VM) running on your second screen and the background of it should be transparent. From the menu Select View > Virtual Screen 1 > Use Host Screen 2. To fix this Hover over the bottom edge of the screen and a small menu should slide up.

Now most likely the virtual machine went full-screen and seamless, but on the wrong monitor. From the menu Select Switch to Seamless mode.Ī small info box will appear, Click Switch. In Virtualbox with the VM running, Click the Machine menu on the VM window. Let’s get the dual-screen setup going! Step 1

Note that this will work with other operating systems on a virtual machine as well, not just Ubuntu.
