Here's my fix for macOS Ventura
cd /System/Applications/Utilities
sudo cp -r Terminal.app/ /Applications/TerminalRosetta.app
Right-Click TerminalRosetta > Get Info > Check Open using Rosetta
Explanation: Applications/Utilities is actually stored on-disk under /System/Applications/Utilities, so when you ls /Applications/Utilities it will show nothing, as it's actually some sort of Finder-specific symbolic link. The /System folder is quite locked down, so we'll have to copy the Terminal app to a directory where we have more permissions before enabling Rosetta. It appears Apple has taken away such permission in Ventura for the entire Utilities folder.
