Apple's next operating system, macOS 10.15 Catalina, has now been through a few beta revisions and had its public beta release. We thought this would be a good time to show you how to make a USB installer for the new OS, for test deployment to your Macs. Similar to Mojave, if you can get it to install and boot, sure, there is no reason you can't -run- Catalina from an external USB-C drive. Given the hiccups involved w/Mojave, however, I'd not bother. If you need to include an external, try parking your Home folder on it, instead, and use FUS to get in.

How to clean install the new software update

Upgrading to macOS 10.15 Catalina is pretty simple. Tap on the Apple icon in the top-left corner of the screen, then go to System Preferences > Software Update to download it. Alternatively, you can download it directly from the Mac App Store.

But sometimes upgrading macOS from the previous version to the latest one is not the best way. You might want to clean install macOS Catalina to give your Mac a fresh start without any issues from the previous installation. Here’s how to clean install macOS Catalina from USB drive:

Steps to install

• Take a full backup of all your important data. Save it to the cloud or an external drive
• You have to create a bootable USB drive. Here’s how you can create it. Make sure the USB drive is at least 8GB in size, and nothing else is stored on it
• Download the macOS Catalina installation file using this link
• Turn off the Mac and then insert the bootable USB drive
• Now turn the Mac back on while holding the Option key
• It will take you to the boot menu where you can select the USB drive. If your Mac has the T2 security chip, you have to first enable booting via external drives from macOS Recovery
• After a while, you’ll see the macOS Utilities menu on the screen. Select Disk Utility and then Continue
• Check to make sure you’ve selected the main drive of your Mac. Also ensure that the format is set as APFS or Mac OS Extended
• Now click Erase to wipe out the drive
• Once the drive has been erased, select Install macOS and then Continue. Just follow the on-screen prompts to clean install macOS Catalina
