NOTE: This entire process requires that you have some type of drive you are able to allow to be erased first, typically a USB flash drive or hard drive. This is a command line tool, so you have to use it in Terminal, which is in your Utilities folder. You just need to go to the Resources folder, and look for something called "createinstallmedia". There will be 10 or so items and folders in there. Open it, and inside is where everything really resides. This will move you one folder deeper inside, but all you will see is a folder called "Contents". To do this, you have to right-click/control-click on the icon and select "Show Package Contents".

I followed mr Macintosh on YT to erase the mac and upgrade in safe mode. I went to the extreme and I regret it deeply. I kept getting failed to personalize the software update Error like 4 times, even when I decided to upgrade only to Big Sur, not Mont. I bought a m1 air a couple of days ago, first ever Apple device, and wanted to do all the upgrades before i start working on it. Plz consider helping me in this super busy time of year.
