As far as I can tell OpenAI doesn't have any Mac apps on the Apple App Store as of now. They have released a ChatGPT app for iOS and iPad but all GPT powered Mac App Store apps are from 3rd parties.

If OpenAI releases a Mac app that doesn't have anything to do with GPT, this still resolves to "yes."

This market will resolve on Jan 1st, 2025.

Please leave any requests for clarification in the comments!

Edit: note that it must be on the App Store specifically.
