How to wipe clean our 2014 Macbook Pro and Install BigSur in one step

We bought New Macbooks and are wanting to give our old 2014 Macbook Pros to two of our children.

Is there a way to do a factory reset on these and Install BigSur in one step?

Thank you!

This method will WIPE ALL Data and there is No Recovery - Period.


>> Only works on Intel Based Apple Computer <<


To perform this action will require booting from a Bootable Installer


The Bootable Installer can Only be performed on an Apple Computer 


This will have to be performed from a Qualifying Computer to run the version of macOS to be made on the Bootable Installer. Example : Bootable Installer of Big Sur would have to be done on a computer that Qualifies to run Big Sur.


Notation: If the computer being used to perform this action is Too New or Too Old to qualify to run the version of macOS - this computer can not be used.


Alternative is, to gain access to a Qualifying Apple Computer from a family member, friend or associate.


1 - Shutdown computer and disconnect all external drive Except the newly created Bootable Installer.


2- Restart and immediately hold the OPTION key until the Startup Manager appears and choose the USB Drive. 


3 - It will present options >> Disk Utilities >> View >> View ALL attached Drives. 


4 - Choose the Upper Most Drive ( not the volumes indented and list below ).


5 - The drive normally is called Apple Media or Apple SSD - that is the drive to Erase and format as APFS with the GUID Partition Map. This applies to macOS 10.14 Mojave and above. 


6 - Once that is done >> backup out of Disk Utilities and choose install macOS. 


7 - Follow the prompts and it may automatically reboot several time. 


8 - Upon a final reboot - Setup Assist will present with the newer version of macOS.
