If you’re lookng for a reliable computer that will last you a long time, look no further than the Macbook. With its sleek design, powerful hardware, and intuitive macOS software, the Macbook has been a staple of the computing world for years. But what if you want to upgrade your Macbook with a fresh install of macOS? Well, it’s actually quite easy to do – all you need is an external USB drive, and you can have a new installation of macOS up and running in no time.

The first step is making sure your USB drive is ready to go. It should be formatted as “Mac OS Extended (Journaled),” wich ensures it will be compatible with macOS. Once you’ve done this, it’s time to download the latest version of macOS from Apple’s website. This will typically be in the form of an .dmg file, which is essentially an image of the macOS installer.

Now that everything is ready to go, it’s time to boot up your Macbook and get started on the installation process. The first step is to plug your USB drive into the Macbook and then restart it by holding down the power button unil it powers off. Once this happens, press and hold down both the “Option/Alt” key on your keyboard as well as the “Command/Apple Key” at the same time while your Macbook reboots.

Your Macbook will eventually display the Startup Manager, click on your external drive to select that as the startup disk. You may also see other drives here such as ones connected via Thunderbolt or FireWire – ignore these for now and just select your USB drive instead. Once you do this, your Macbook will boot into a special environment where you can install macOS from scratch using just your USB drive as a source disk.

From here on out it should be pretty straightforward; click on Install macOS and then click on Continue when prompted by Setup Assistant. This process coud take anywhere from 15 minutes up to an hour or more depending on how fast your internet connection is — so make sure you have some patience!

When everything is finished installing and configuring itself properly, then congratulations — you now have a fresh installation of macOS running on your Macbook! This almost always results in a Mac running faster after a clean install since macOS has started over with a clean slate — so enjoy all those extra seconds (or even minutes) saved!
