Then follow these steps for Sonoma (14.8.7):
softwareupdate --fetch-full-installer --full-installer-version 14.8.7
hdiutil create -o /tmp/Sonoma -size 16000m -volname Sonoma -layout SPUD -fs HFS+J
hdiutil attach /tmp/Sonoma.dmg -mountpoint /Volumes/Sonoma
sudo /Applications/Install macOS Sonoma.app/Contents/Resources/createinstallmedia --volume /Volumes/Sonoma --nointeraction
hdiutil detach /Volumes/Install macOS Sonoma
hdiutil convert /tmp/Sonoma.dmg -format UDTO -o ~/Desktop/Sonoma.cdr
mv ~/Desktop/Sonoma.cdr ~/Desktop/Sonoma.iso
rm /tmp/Sonoma.dmg
Or for Monterey (12.7.6):

Back in the day it was possible to connect to a specific site on a specific ip, just by supplying the host header.
curl -v -H "Host: www.example.com" https://127.8.4.2
But with tls1.3 strict SNI checking, the host header isn’t enough.
It is, however, possible to override dns by using the –resolve override.
curl -v --resolve www.example.com:80:127.8.4.2 https://www.example.com
