One important advantage is getting rid of junk apps and files that have accumulated over time so that you can start over with a clean slate. But that doesn’t mean performing a clean installation doesn’t have its advantages because it does.

Performing a clean installation: One reason why users like macOS is that it doesn’t degrade over time, becoming slower and less reliable.

For example, you can regain access to a Mac that’s refusing to boot or recover files that seem to be lost.

Using built-in recovery tools: Bundled with the macOS installer are useful recovery tools that you can use to troubleshoot and fix all kinds of issues.

If you have multiple Macs, then it makes sense to install it on each machine from a single macOS USB installer, instead of downloading it separately every time.

Installing macOS without re-downloading it: macOS Monterey is around 12 GB large.

Still, there are some situations when having a bootable flash drive with macOS at hand comes in handy: When a new version of macOS is released, you simply go to System Preferences, click Software Update, and let the installer do its job. Mac users enjoy a hassle-free upgrade process that, for the most part, eliminates the need to fumble with installation media. Why It’s Useful to Know How to Make a Bootable USB on Mac?
