In macOS ventura I cannot duplicate my terminal app.

I want to do this as I have a M1 processor and I want to have one that opens using Rosetta2 and one that opens natively.

Any ideas how to get around this?

    It was never obvious (to me, anyway) how to start multiple instances of the same executable in macOS. Have they really disabled the ability to do that, or do you just need help finding out how to do that? (Either way, apple.stackexchange.com is probably a better site to ask at.) – chepner Oct 31 '22 at 20:45

An alternative is a workaround posted here (to save you some time, I'm transcribing it here):

In your ~/.zshrc file, add these two lines at the end:

alias arm="env /usr/bin/arch -arm64 /bin/zsh --login"

alias intel="env /usr/bin/arch -x86_64 /bin/zsh --login"

From now on, from any new terminal window, you can type in intel or arm whenever you want to switch between using Rosetta2 or not, respectively

I ran into the same issue, needing a Terminal in Intel/Rosetta-mode to work with Azure Functions.

A simple workaround is to install a Terminal alternative, e.g iTerm 2, and set either that or Terminal to run in Rosetta mode.

    Thank you, yes this is what I have been doing also. Any idea why there is not the option to duplicate certain apps in ventura? – ushham Oct 26 '22 at 15:31

    Utilities % sudo cp -R Terminal.app Terminal-Rosetta.app cp: Terminal-Rosetta.app: Operation not permitted cp: Terminal.app: unable to copy extended attributes to Terminal-Rosetta.app: Operation not permitted I get an error like this from terminal.. Here is an article explaining a bit about the error message and it suggests using rsync instead: https://www.quora.com/What-isnt-copied-when-Mac-OS-Xs-CP-complains-extended-attributes-not-copied Rsync however gives me similar error. – Waltari Nov 11 '22 at 09:31

I found the following solution the most helpful (Source)

Reason for failing: Apple disabled in OS Ventura the option to duplicate Terminal.App and rename it.

% env /usr/bin/arch -arm64 /bin/zsh --login
% arch
arm64 


% env /usr/bin/arch -x86_64 /bin/zsh --login
% arch
x86_64

Add the following to your .zshrc file:

alias arm="env /usr/bin/arch -arm64 /bin/zsh --login"

alias intel="env /usr/bin/arch -x86_64 /bin/zsh --login"

Now, when in Terminal app, you can switch arch by using the aliases.
