How to Install and Run macOS Beta Version Alongside Stable Version
Want to install the latest macOS beta version without risking your data or disrupting your workflow? There is a way to install the beta version on a partition and run it along with your trusted macOS stable version. Basically, you will have two operating systems on your Mac – one stable and one beta. This approach lets you explore the new features of the beta version without compromising your current setup. Here are the steps to create a partition on your Mac and install the macOS beta version. We will be installing macOS Sequoia for this guide.
Installing the macOS beta version on a different partition of your Mac involves these steps:

Step 3 – Access Both Stable and Beta macOS Versions
To access the installed macOS beta, start by shutting down your Mac. Hold down the power button until the startup options screen appears. From there, select the partition where you installed the beta version, and your Mac will boot into it.
To return to your regular macOS, simply power on your Mac as usual. The stable version will boot by default unless you change the settings.

If you want the beta version to be your default operating system, go toSystem Settings,thenGeneral, and selectStartup Disk. Choose the partition with the beta installation and click onRestart. Your Mac will boot into the beta version automatically every time you start it up
That’s it! Similarly, you may run three or even more macOS versions on your Mac. Simply create a partition, install the macOS version, and select the desired partition for installation. However, you will need much more storage and raw performance to pull it off. This process works not only for installing beta versions but also for setting up two different stable OSes if that’s what you prefer.
