How to fix broken Apple Script in Numbers after latest update?

There does seem to be some issue with AppleScript in Numbers Creator Studio. From what I can tell it's related to having two copies of Numbers installed and it seems to have trouble targeting the different versions.

For now, though, there's nothing to stop you continuing to use Numbers 14.5. From what I can tell, scripts continue to target and work in the old version.

This thread lead me to a solution in a way, Thank you Camelot. For me no need for the older version of Numbers 14.5 with the newer version installed so I removed it. My only issue was that the script was not listed in the services menu in Numbers. It ran manually when I tested so I knew the script wasn't broken. I opened my script in Automator and Reselected the Numbers.app (15) and resaved the script. It is now listed in the services menu. Retargeting the Workflow receives [no input] and in [numbers.app] added both numbers and numbers core studio app). I did get a few permission errors when I first ran the script but subsequent execution worked as before. Hope this helps

This is a user-to-use forum so don't expect an answer from Apple. I share your frustration, though. It won't be the first time that scripting for Numbers got messed up.

You will have to provide a lot more information if you want help from the forum. Post your script and tell more about what the problem is. Right now all we know is you have an AppleScript that used to work but now does not. We may or may not be able to help but we need more info to even try. It probably won't be me helping because I am waiting on installing 15.1, so I won't be able to replicate the problem or test any solutions. I quit being an early adopter a while back, for reasons similar to yours. But if something stands out, I might chime in.

It would have helped if you'd mentioned that you were using Services, rather than AppleScript, directly. To be fair, though, I didn't ask, specifically.

Internally, Numbers 15.1 is called 'Numbers Creator Studio' vs. Numbers 14.x's simple "Numbers". Hence scripts that target just 'Numbers' wouldn't map to the new version.

It might have been nice for Apple to find a smoother way of handling this, especially since Numbers 15.x shows in the Finder as simply 'Numbers', meaning most people don't realize the different underlying names.

Either way, glad it's resolved for you.

Sort-of true that you can continue with the old version of numbers…. You will get the “out of date message” that will interupt the script… but anyway that’s not really the point. My experience is that it still works but but has slowed down… the same script runs maybe 10 times slower.
