I am using multiple macOS profiles and I’m switching between them quite often. I can use the ChatGPT macOS app just on one of them at the same time:
" You can’t open the application “ChatGPT.app” because someone else is using it.
Ask the other user to quit the application, and then try again."
Why is there such limitation?
mac: Apple M1 Max
system: macOS 14.5 (23F79)
chatGPT.app version: 1.2024.170 (1719338033)
Same issue here! Any news on this, OpenAI team? Thanks, G.
I’m wondering about this as well. Seems like a strange limitation, especially since you can still login with multiple users on a web browser.
Any official word? 
I ran into the same issue. Looks like the Obsidian team ran into the same issue and identified a fix:
Seems to be caused by the misleadingly named
LSMultipleInstancesProhibitedwhich sounds like it would make the app single instance, but actually prohibits it from running under multiple users.

Seems simple enough if it’s the same issue, which it likely is. Would be great if someone from the OpenAI dev team could look into this.

Still same issue and we’re in November…
