How to Do Fresh Install of Mac Os?

Performing a fresh install of macOS can help resolve various issues on your Mac, such as sluggish performance, frequent crashes, or software conflicts. It also allows you to start with a clean slate, ensuring a smoother and more stable operating system. In this tutorial, we will guide you through the steps to perform a fresh install of macOS.

– Select your USB flash drive from the sidebar.
– Click on the "Erase" button, choose "Mac OS Extended (Journaled)" as the format, and click "Erase."
– After the erasing process is complete, close the Disk Utility.

Now, you need to use Terminal to create a bootable installer. Open Terminal (located in "Applications" > "Utilities") and enter the following command:

"`
sudo /Applications/Install macOS [version].app/Contents/Resources/createinstallmedia –volume /Volumes/[USB Drive Name] –nointeraction
"`

Overall, the time required to install macOS Monterey from scratch can range from a few hours to half a day, depending on the factors mentioned earlier.
