Backup your Mac

I can’t stress how important this is. You must backup your Mac before you do anything else. You’re going to be erasing your startup drive completely, so you need a complete backup of everything. You can use Time Machine, another backup app, or a cloning tool. Just make sure you have a complete, preferably bootable, copy of your current installation.

You should also make notes of settings for apps you use regularly – screen grabbing them is a good way to do that. And you should make sure you have a copy of any licence codes that you’ll need when you reinstall applications. You can use Apple’s Notes app to make notes, as long as you sync them with iCloud.

Create a bootable installer of macOS Catalina

If you’re reading this after Catalina ships, you can download it from the Mac App Store and then choose Quit when the installation starts. If you’re clean installing the beta (and, by the way, that’s not something I would recommend. It’s much better to create a dual boot system when you run the beta.

  1. Grab a USB stick with a capacity of at least 16GB, or an external hard drive or USB.
  2. Go to Applications>Utilities and launch Disk Utility.
  3. Launch Disk Utilities and Erase the Drive or USB stick, formatting it as Mac OS Extended (Journaled) or APFS and selecting GUID partition map if a selection is available.
  4. The easiest method for creating a bootable installer is to use DiskMaker X. However, if you’re comfortable using Terminal, you can do it like this:
    1. Launch Terminal from Applications>Utilities
    2. Type: sudo /Applications/Install macOS Catalina Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install macOS Catalina Beta.app where ‘Untitled’ is the name of your USB stick or external hard drive
    3. Press Return and wait for the word Done to appear in Terminal.

Once you see ‘Done’ in Terminal you can quit it. Your USB stick or external hard drive is now a bootable Catalina installer, so keep it safe. Now, it’s time to clean install macOS Catalina.

  5. When Disk Utility launches, choose the Eras tab then select your startup volume (probably called Macintosh HD).

You can now restore files you backed up earlier from Time Machine or whichever backup tool you used. Remember to restore files and folders individually, don’t, for example, restore your entire user directory otherwise you’ll copy back all the junk files you just got rid of. Reinstall applications and go through them adding license details where necessary. Check that everything works as you expect it to and use the screen shots you made earlier to configure settings.

However, since Apple initiated a relatively new partition scheme (APFS) with macOS High Sierra, the process is slightly different than with older versions of macOS. This article shows you how to set up a new SSD with macOS Catalina that you can boot from.

Why Installing macOS Catalina on External SSD?

macOS can be installed on an external storage device by default, such as HDD, SSD or USB flash drive. And this priciple also applies to macOS Catalina.

After all, if you're upgrading to macOS Catalina, you want your Mac to boot to it all the time, don't you? Not necessarily. There are several reasons why you might not want to disturb your current installation, whether it's Catalina or an older version of macOS. Here are some possible reasons.

● You might want to try macOS Catalina without having to uninstall and roll back to Mojave or High Sierra if you change your mind. Uninstalling and rolling back to an older version of macOS is time-consuming and a tedious process that is prone to errors, so you may not want the hassles that come with it.

● Your Mac (Mostly Mac Mini or iMac) is built upon on a HDD and it runs slowly. You are looking for a way to boost the performance without untouching the internal drive.

● Since there are bound to be bugs in early versions of any new OS, you might want to avoid the hassle of having it as your default OS. This way, you can update it as new versions are released, then install it as your main OS when you're happy with the stability of the software.

● You may want to have the SSD run macOS Catalina on more than one machine. Since your SSD is essentially an external drive that is portable, you may want to switch it between one Mac and the other. Instead of installing Catalina on both, you have the flexibility of simply connecting the SSD to one of the Macs when you want to boot from it.

● It's also possible that you want to run a different set of apps and, therefore, need more memory. If you use a larger-capacity SSD, this will allow you to load a ton of heavy apps like Photoshop and so on, which might not be possible with your current hard drive because it is already full of data.
