After the clean install process, your MacBook will be like new. So it will work faster and better. For example, I had a lot of junk files, some useless apps, and games - now my computer is clean and fresh. Actually, I noticed that it works much faster now.

If you want to boot from a USB flash drive on intel Mac's you need to hold down the Option(alt) key while booting, not CMD+R as this will take you to the internal recovery partition if it has one.

Excellent instructions!
I ran into the following error: APFS disks may not be used as bootable install media. An error occurred erasing the disk. I was able to resolve using Disk Utilities by creating it as a full partition (since reformatting gave me no other choices but APFS choices) and selecting FAT. Seems the disk gets reformatted during the process anyway.

I’m guessing the Rest Mac command jn settings doesn’t clean the hard disk??

I followed the process. After I erased the internal disk. I shut down the computer. I then started the computer. The only option I was prompted with is choose network. I then had to choose my WiFi network and input the password. I never got the option to boot or install from mounted disk

Can we install if it was formatted without writing the above code in terminal?

What if I already erased my Mac and don't have a bootable USB. Can I create a bootable from other Mac and use in mine?

[GoodNewsD]

Please it says 128GB is not valid volume mount point

[BatuKhan-vtki]

In the bootable USB you have to enter the password or Apple ID?

In years past I used to clean install my Mac every time a new edition of macOS came out. But now I don't bother to do a clean install as it is a hasle to reinstall all the apps I use and set up my email accounts etc. I look forward to macOS Sonoma. I might to a clean install of macOS Sonoma if my Mac is having performance issues.

A software update is required to use this startup disk

Internet installer is choppy so I have to do it using bootable drive
