Managed to solve it. Eject the VirtualBox image from: Finder > Devices Now allow the exception in: System Preferences > Security & Privacy Finally but not least click Allow button so that way the developer with the name "Oracle America, Inc" will be accepted and the installer using that certificate will run just fine (basically this installer is ...

Does not work on Mavericks and Yosemite There is no way to legitimately get the file without having access to a Mac, and a licensed copy of the OS via a purchase (unless you are a member of the Developer Program, for which you can expect to pay far more than the cost of the OS, what with it being free). But if you can blag some access time on a Mac, then you ...

It's not by default. If you have installed Guest Additions, then you can do this: Start the VM Go to Machine > Settings in the file menu. Go to the General tab, then Advanced. Set the Shared Clipboard setting to Disabled, Guest to Host, Host to Guest or Bidirectional.

To install and/or use virtualbox you may need to enable its kernel extension in: System Preferences → Security & Privacy → General For more information please refer the documentation or this Apple Technical Note: https://developer.apple.com/library/content/technotes/tn2459/_index.html

High Sierra comes with a new security feature: Secure Kernel Extension Loading, which blocks kernel extension loading. The implementation appears to be questionable. To allow the loading of some non-Apple kernel extension you have to either allow execution in Preferences > Security & Privacy > General: or disable the security feature with a Terminal ...

By default it's the right ⌘ (Command) Key. The left ⌘ (Command) Key does not work because it is set as the Host (Meta) Key in VirtualBox. And they can be swapped simply by replacing the Host Key with the right ⌘ (Command) Key, in Preferences > Input > Virtual Machine > Host Key Combination.

If your host system is OS X, you can follow the instructions on: http://ntk.me/2012/09/07/os-x-on-os-x/ Requirement: - Install OS X.app purchased in Mac App Store - iesd VirtualBox Settings: - Operating System Version: Mac OS X (64 bit) - Base Memory: 2048 MB (larger is better) - Enable EFI In the lastest VirtualBox, all the default settings work well. ...

I just had a similar issue and resolved it by: going to System Preferences > Security & Privacy > Privacy. Click the "lock" icon to make changes. Scroll down the list on the left-hand side and select "Full Disk Access" Click the "+" icon on the right and select the Terminal app (or in my case iTerm) You'll now be prompted to close the app if it's ...

I'll quote a previous answer of mine: From Virtualbox Manual : Chapter 14: 14.2. Known Issues Mac OS X guests: VirtualBox does not provide Guest Additions for Mac OS X at this time [snip] From the content of this, I wouldn't hold out for such support in VirtualBox any time soon. The situation really has not changed since then. There is some discussion of ...

The answer above by @stuffe won't work on Mavericks. Apparently Apple has changed the format of the ESD image and it's no longer bootable. Looking around I've found a couple of pointers on how to do the necessary conversions to get the result as something you can boot a VM off. Depending on what's the purpose of the ISO file, if it's to reinstall a ...

First, you need to buy Mountain Lion (if you haven't bought it already). Go to Apple's web store (not the App Store app), and search for "Mountain Lion", and pay $20 for it. Wait 3 days. Even though they're just emailing you a PDF with a license code, it's done manually (so I'm told), so it really does take 1-3 business days to get to you. In the App Store ...

You need to press "host key" which is written in right bottom corner of VirtualBox window. Looking at your screenshot its Right Ctrl. Its not default Mac Command ⌘ because you are running VirtualBox on Windows host, which you are accessing using TeamViewer. See virtualBox manual: link

I found the solution myself. All I need was to eject usb pen drive from mac's desktop. When the drive ejected, it became available in VirtualBox.

I also followed the guide at http://web.archive.org/web/20181103074214/http://danielphil.github.io/windows/virtualbox/osx/2015/08/25/virtualbox-boot-camp.html I will add what challenges I had following that guide, but I was able to run my BOOTCAMP partition using VirtualBox, which is free, so I'm happy. First, you should have installed: Windows 10 x64 ...

The dmg file (Install OS X El Capitan.app/Contents/SharedSupport/InstallESD.dmg) is no bootable image. To create a bootable file use the following script. You may have to modify some paths (i.e. the user name in the last line and the path to Install OS X El Capitan.app (and the inner InstallESD.dmg file) in the 6th line): #!/bin/bash # Create bootable ...

Guest Additions are available for macOS starting with VirtualBox 6.0 Per the change log, macOS/OSX Guest Additions are at "initial support" meaning features/functionality could be limited.

If you've used Migration Assistant I'd moved from an old machine running macOS Mojave to a new machine using macOS Catalina using Migration Assistant. This bypassed the normal installation process, so the Security & Privacy System Preference never displayed a prompt that would allow me to grant VirtualBox permission to run. The solution was to download ...

Yes, it's possible. First you need to create the virtual machine, after you completed the wizard don't start the VM but go to the menu Machine -> Show in Finder Copy the 3 files (VM Name.vbox, VM Name.vbox-prev, VM Name.vdi) to your external hard disk. After select the VM inside virtualbox and go to menu Machine -> Remove... and click the button Delete ...

There is no official way to run OS X on a virtual machine in Windows. The Apple EULA clearly states under section 2 B that you're allowed to: (iii) to install, use and run up to two (2) additional copies or instances of the Apple Software within virtual operating system environments on each Mac Computer you own or control that is already running the ...

Update 02/03/2020 Kinto - Type in Linux like it's a Mac. Kinto has now been rewritten in C for Ubuntu/Debian systems using x11. It also uses json config files, making it easier to manage and extend to other applications than just terminals. The app no longer maps to Super in the Terminal apps, it will now properly map to Ctrl+Shift to create the exact same ...

AFAIK the shared folder feature of VirtualBox only works with the VirtualBox guest additions. The additions can't be installed in a OS X/macOS guest. Thus you can't use this feature. Instead share a folder in the OS X/macOS guest system by enabling "File Sharing" in System Preferences > Sharing > File Sharing. If the default public user folder is not ...

Your final HighSierra.iso is missing the complete InstallESD content (AKA the real High Sierra installer). You just copy a probably defunct and thus non-bootable base macOS system to the image. I use the following shell script to create a working macOS installer iso file. Basically it's the same method as Apple's recommended way to create a bootable macOS ...

This was (or obviously still is in VirtualBox 5?) a known bug of VirtualBox 3 which should have been fixed in 4.0.0! The workaround is disabling the use of the new async I/O code... done by ticking "Use host I/O cache" for the SATA (and SCSI) controllers.

For those still struggling with this issue: IF YOU ARE CONNECTING VIA REMOTE DESKTOP OR SCREEN SHARING or have any other mouse emulation running: It is not possible to actually click the Allow button in this mode!!

Big Sur is a developer beta, not a public release beta. The difference being is that it's released to software developers so they have a relatively decent platform to begin work on getting their applications compatible with the new release of macOS. It's not meant for end users to gain access to the bleeding edge of macOS tech because you want the latest ...
