Select “Reinstall macOS”, then click Continue. You’ll need to select the proper language for the installation, and then the macOS Utilities window appears on your screen. If it is, just click Install and the Mojave installation begins. We need to create an up-to-date Mojave VM before we can update it to Catalina.ģ – Click the Apple icon next to the Install title, then click Continue.Ĥ – A screen appears telling you that your computer must be connected to the Internet. Once Parallels Desktop is ready to roll, follow these instructions:ġ – Launch Parallels Desktop, then select File > New from the menu bar.Ģ – In the Installation Assistant that appears, scroll Free Systems to the right until you find “Install macOS 10.14.5 Using the Recovery Partition”. If you don’t, you can pick up a copy from for $79.95 by clicking this link. I’m assuming that you already own a valid license for Parallels Desktop. Just be aware that this is not an optimum test of Catalina. Other than that, you can see what the new OS looks like, launch the new or revised Apple apps, or try out your apps to see how they work. Right now, you can indeed load Catalina, but it will run slowly, you might need to make settings changes to access the internet, and there are issues with moving windows and icons.

In the past, it has sometimes taken a month or two for Parallels Desktop to support new beta operating systems fully. So why am I saying you might want to wait? macOS Catalina is definitely beta software, and since Parallels Desktop mimics a Mac in software, it is integrated very tightly with the operating system. But for those of us who just have one Mac and don’t want to necessarily dedicate a spare disk drive to experimentation, Parallels Desktop is a very good way to test the new versions. Usually, macOS beta versions run quite well - although slower than you’d expect - on a Mac set aside for running the beta software or off of a boot drive set up with the new OS. For bloggers, it’s a chance to test out the new capabilities of the OS, while it’s critical for Mac developers to test their software on the new version. In this article, I’ll show you how to set up macOS 10.15 Catalina in Parallels Desktop, but first I’ll tell you why you might want to wait… Why Wait?Įvery time Apple comes out with a new version of macOS, the first thing bloggers and developers try to do is get the beta versions up and running. This is usually a good way to try out a new operating system without the need to create a new boot drive or use a second test Mac, and I’ve done it with previous macOS versions.

A vacation and some oral surgery delayed my experimentation, but I decided to give the new OS a try in a Parallels Desktop virtual machine. Like many developers and tech writers, I wanted to start working with macOS 10.15 Catalina as soon as I could.
