Step 1: Extract the macOS (11.0) VMware disk image file Browse to where you saved this file “macOS 11.0 Big Sur by MK.zip”, and extract it with the Windows Utility. It may take while, so you can proceed to the next step while it is running. Software size The first difference is the inflation on the size of the software. The System folder of macOS 11 Big Sur takes twice as much space as macOS 11.15.6 Catalina, 22 GB instead of 11 GB. Xcode 12 weights 28 GB against 18 GB for Xcode 11.

This article is intended for educational purposes only, to demonstrate that it’s possible to test out iOS applications with Xcode without having to buy a Mac. However, you should consider testing on a real MacOS device before publishing your application on the App Store.

All the Steps to Get Your First 'Mac'

OK, now let’s discover how a 'Mac' is made. How to speak sindarin elvish.

Requirements

You’ll need a computer running Windows or Linux (not tested) and an iOS device (iPad or iPhone). Also required:

VMWare or VirtualBox
USB 2.0, not 3.0
An Apple Developer account
Xcode 10.1 (no other versions)

VMWare or VirtualBox?

After having tested various MacOS versions on different virtual machine systems like VMWare and VirtualBox, I found that the quickest solution was VMWare Player 15 with High Sierra 10.13.

Newer versions of MacOS drastically reduce the performance of the system, probably due to newer graphic drivers that aren’t 100% compatible with VM software.

First steps

The first step is to install your VM:

Switch USB

After your VM is fully connected and active, you’ll want to try out the connection to a real-world iOS device.

On VMWare, you have to switch the USB mode from 3.0 to 2.0 to let the 'Mac' see your Apple device.

Once you have that handled, reboot the VM and connect the device while opening iTunes inside the VM. After a few seconds, you should see the device pairing to it.

Apple Developer account

Next you’ll need to prepare your Apple Developer account. Don’t worry, it’s free while you’re testing applications on your local device. You only have to pay to publish your app on the App Store.

Register at developer.apple.com
Login and proceed to developer.apple.com/download/more/
Search for Xcode 10.1 and download this XCode zip file, around 5.6GB
Unzip the file and move the App file to the Applications folder.

Xcode version must be 10.1

Install Xcode Macos

You should never download any version of Xcode except 10.1.

Macos Xcode Command Line Tools

This is because newer versions aren’t supported on High Sierra 10.13.6. Some people have been able to use the newest version, but it would require modifying some app files and would just make it harder.

If you get the 10.1 version, however, you’ll be ready to code in a few minutes instead of a few hours.

Get some support

There’s a downside to using Xcode 10.1.

New iOS versions, like iOS 12 or 13, aren’t supported on it. So if you try to run your app on an iPhone with iOS 13, you’ll get a warning that it can’t install on that device.

Luckily there is a really simple fix thanks to this awesome repository on Github. Open up your terminal and type these commands:

Easy!
