I Tried Installing macOS on a USB Drive!

I Tried Installing macOS on a USB Drive! Can you run a full desktop operating system from a USB drive? In this video, I try Installing macOS on an external USB drive to find out whether it can work as a portable Mac setup. The idea sounds simple, but Installing macOS outside the internal drive comes with a lot of unexpected challenges. The goal was to keep my main system untouched while Installing macOS on a separate USB drive. This way, I could test macOS without wiping my existing operating system or risking important files. But as soon as the process started, I realized Installing macOS on external storage is not always as smooth as it sounds. Throughout the video, I'll walk through the full process of Installing macOS, from preparing the USB drive and creating the installer to choosing the right target disk and fixing boot problems. I also explain what went wrong, what worked, and how long Installing macOS actually took on a USB drive. After Installing macOS successfully, I tested real-world performance to see if running from USB is practical. I checked boot time, app launch speed, responsiveness, storage performance, and everyday usability. The results were both surprising and frustrating. This experiment is perfect for anyone curious about Installing macOS without fully committing to it. Whether you're testing compatibility, experimenting with old hardware, or simply trying to create a portable setup, Installing macOS on a USB drive can be useful—but it definitely has limitations. Watch until the end to see whether Installing macOS on a USB drive is actually worth it.
