How To Reinstall & Clean Install macOS Catalina With Bootable USB Drive

Advertisement

For weeks now I've been having two major issues with my MacBook. It tends to reboot at random while sleeping and iMovie just doesn't export my video creations at the exact quality level I set them to.

Over the weekend, I got tired of this and decided to do a clean reinstallation of macOS Catalina.

I feared I would crash my MacBook while doing this but it went well so I'm giving you guys a detailed guide of how I achieved it. I've made up my mind to always do a clean install each time a new macOS version is released. All the bugs I've been experiencing are gone....for now.

Less I forget I've got a Windows 10 bootcamp partition on my MacBook and fortunately this whole process didn't affect it in any way and for that I'm really grateful.

I'm also grateful for Globacom Weekend Data Plan of N500 for 3GB of data. It really made the process less tasking on my pocket as the downloads were quite heavy. Over 24GB of data went into restoring my MacBook.

Don't forget to create a time backup immediately you're done so you don't have to go through this process again.
