This post will explain how to build your own bootable Monterey USB disk!

 

istockphoto 481022634 170667aA bootable disk is a much more convenient procedure to use than the ‘recovery mode’ . Recovery will not always start with the latest build or version of Apple’s software as this also depends on your hardware used. ( production year ). You may startup with Mojave, Big Sur depending on your used system and then proceed  with some software updates which should end up in an equal system state as a straightforward installed bootable system disk . However I feel that any mayor software update will leave some traces of the upgraded software in your Mac’s system.

Why a clean install of macOS Big Sur is good

It gives you the opportunity to rid your Mac of unnecessary bloat. All of those apps you tried once but decided you don’t like? Gone. All of those downloads you never did anything with? Erased. Everything is clean and fresh and ready for a new start. This procedure will give you best performance of your system.

PROCEDURE

Insert a min 16Gb USB stick and open the disc utility from your apps. Now format the disc as
Mac OS Extended (journaled) **  , and open Terminal from your Mac’s utilities and type:

sudo (don’t Enter or whatever, leave the curser)

find your downloaded ‘Install macOS Monterey.app’ and right mouse-click  ‘show package contents‘, now open Resources and locate the ‘createinstallmedia

Monterey Install@2x

Now drag this file to your still open Terminal and paste it just after ‘sudo“, you should sendup with a command like stated below !

Next, type two and type volume (again leave your curser alone ), now go to your Finder menu and choose ‘GO‘, this will make you choose your USB disk! Now drag your disc into the still open Terminal and paste it after ‘volume‘. (see below)

Now you may enter, and the Terminal will ask you for your Password, and type ‘Y’, to continue

Get yourself a cup of Tea now and wait for the process to complete .
