The following article describes how to set up your Mac to run Windows 8.1 and run Windows RT.

The following instructions assume you already have Windows 8 or 10 on your system.

For a list of operating systems and their features, refer to the respective Mac OS 10.9.1 or 10.10.1 article.

Note: If you are upgrading from a previous version of OS X, you may need to make a hard reboot to install the new OS.

You can get your OS X installation back up and running in the Mac OS Finder, as explained in the following article.

Mac OS 9.5.3, 10.7.4, 10, 10 and 10.11 are required to run on your Mac.

MacOS X 10 (High Sierra) and Mac OS 11 (Snow Leopard) are also required.

If you’re installing Windows, you can also use the installer from the Windows 8 site.

Windows 8 is the recommended version.

Download the installer here.

If the installer fails to install properly, you should try running the installer as Administrator and try again later.

If it still doesn’t install, check the installation options in the installer to make sure it’s installed properly.

Open a Terminal window.

Type cd /Applications and hit Enter.

In Terminal, run the following command to install Windows RT: wget tar xzf windows-rt.tar If you downloaded a zip file, the installer will create a folder in the directory you specify.

If that directory does not exist, type mkdir -p /Users/YOURUSERNAME/Library/Application Support/WindowsRT/ and hit enter.

Next, you’ll need to run the installer.

Type: cd /Users/.local/Applications && ./ And that’s it.

When you reboot, you will be asked to restart your Mac and to confirm that the install completed successfully.

You may have to repeat the installation process several times.

If your Mac doesn’t boot, check that you have a working copy of Windows RT installed and run: ls -l /Users/*/Library-Application-Support/Windows RT/ && ls -la /Users/(YourUserName)/Library-Item-WindowsRT-Installer-0.0.9-1.pkg-amd64.pkg/ && rm -rf / Now, open Terminal and type: ps -ef | grep ‘Mac OS X’ In Terminal window, type: ls The output should look something like this: /Users[[email protected]]:~/Library/*/Applications/Windows\RT-installers/Windows_RT_0.1.0-win32_64-msie.app_cache/Installer.pkg /Users{[email protected]@ip}:~/Applications/*/Windows-RT_installers-0_0_5.0_win32.deb /Users:[[email protected]@ip]:~# ls /Users /Users’ Installer installed.

Please reboot to continue.

Note that this command does not install the Windows RT application.

If this doesn’t work, check you have Windows RT correctly installed.

Open up your Terminal window again and type the following to install a version of Windows 10 from the Apple Store: wmic osx | find “Install name” | grep “Mac OS 10” and hit The output will look something similar to this: Install nameMac OS 11(Wily Werewolf)Install nameMac Windows RT(Windows 8.0 and 10)Install NameMac OS x(10.8 and 10).app_idInstall nameInstall nameInstallation nameInstall NameInstall nameIf you are getting this error message, it means your installation was failed.

Open Terminal window and type sudo update-alternatives –installer windows-10-10.10 –user yum Installer is about to install.
