Creating a Virtual Machine of Xcode 9 Beta

Creating a Virtual Machine of Xcode 9 Beta

Scenario: 
1. You have an Apple Developer subscription.
2. You currently have several apps that you need to maintain/update before Xcode 9 is officially released.
3. You don't want to install Xcode 9 beta on your Mac - but you still want to play with the Xcode 9 beta.

One Possible Solution:
Use Parallels to create a virtual machine of macOS then install Xcode 9 beta on it.  

Step 1: Get macOS Sierra (current Version)
a. Open the App Store application on your current version of macOS.  
b. Search for: macOS
c. You will see macOS Sierra listed in the results.  Assuming this is already installed, click download.  It's over 5GB so this will take a while.
d. Confirm the download by using Finder to view the Applications folder.  You'll see 'Install macOS Sierra'.

Step 2: Create a Virtual Machine of macOS Sierra using Parallels
a. Install Parallels (version 12 used for this gist).
b. Launch Parallels.  Choose 'Install Windows or anotehr OS from a DVD or image file'.
c. Select the macOS Sierra image file you downloaded from Step 1.  Choose 'Continue'.
d. Create a disk image (e.g. OS X image file.dmg)
e. Name the virtual machine (e.g. macOSSierra-Xcode9)
f. Choose 'Install macOS' and 'Continue'.  Go through the install workflow.

Step 3: Install Xcode on your virtual machine 
a. Sign into the Apple Developer program.  Navigate to the downloads page: https://developer.apple.com/download/
b. Download the Xcode 9 beta and install it.
