If you want to install macOS on multiple computers, but don't want to download the installer every time, then the bootable installer will be very useful. Let's take a look at the tutorial of making a USB boot disk for Apple Computer.
1. Download MacOS from the App Store

2. Prepare a 16G or more U disk or mobile hard disk, open "Applications → Utilities → Disk Utility" to erase (format) the U disk
Name: MyVolume
Format: Mac OS X Extended (Journaled)
Scheme: GUID partition map
Note: The name of the U disk is "MyVolume". The name of the drive letter must be the same as the name in the following command. It needs to be carefully checked. Many beginners are prone to mistakes here)
3. After the U disk is erased, open "Applications → Others → Terminal", enter: sudo + space + App address + /Contents/Resources/createinstallmedia + space + --volume + space + U disk address
code show as below:
Ventura
sudo /Applications/Install\ macOS\ Ventura.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
Monterey
sudo /Applications/Install\ macOS\ Monterey.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
Big Sur
sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
Catalina
sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
Mojave
sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume
