Total mess. Followed codex update advice for mac app. Codex then disappeared. Updated Chatgpt (as advised app), no ‘Work’ version available, just model updates from what I can see. So now I cant work in my codex projects unless I re-set them up in Codex cloud (if it even exists now?), and obviously my local mac projects/chats will not be synced, absolute nightmare. As an added bonus, when contacting support over this, supports not working so effectively ive already lost about 4 hrs of work. Im a $200 a month pro user.
Annoyed is an understatement!! OpenAI WTF were you thinking! I can’t find my chats, projects, everything is missing. Absolute shambles of a decision to do this.
All of Codex data is missing. Gemini helped me to make a backup of my Codex files, which ChatGPT support was unable or unwilling to do. I still don’t have access to the Codex app in the new ChatGPT app which I reinstalled. The system shows this issue as resolved which it is far from being resolved!
Same issue here, Codex disappeared suddenly. ChatGPT App for Mac shows that there was an update available but raises an error when updating. Then, after removing the ChatGPT App and downloading and installing the new ChatGPT App version, I got the new ChatGPT Codex version with all code, branches, etc worked previously in Codex! Hope that works for you as well.
July 10th, 3pm EST. This is a complete mess, never been so disappointed with an update. Actually, this update bug has been going on for a while, now, every time I send a prompt codex is freezing. I already have the version with the chat option. What a horrible update! Today I really needed to make progress, and this is really stoping it all!
Had the same issues - but chat (I call him Chuck) walked me through it, now Codex is loading now but no chats, and its not loading my profile - but its working on iPhone, iPad, and Chrome. Its provided an email to send to support.
Hello,
I’m experiencing an issue with the latest ChatGPT for Mac app.
System details
macOS Tahoe 26.5.2
ChatGPT for Mac version 1.2026.183
ChatGPT Plus subscriber
Issue
After installing the new unified ChatGPT/Codex app:
Codex loads and works correctly.
The Chat workspace does not function.
Clicking Chat only opens the side panel.
Sending a message returns “Request failed with status: 403”.
Earlier, the app also displayed “We’re having trouble loading your profile.”
The app does not appear as an authenticated desktop session under Security & Login.
What works
ChatGPT works normally in Chrome on the same Mac.
ChatGPT works normally on my iPhone.
ChatGPT works normally on my iPad.
What I’ve already tried
Reinstalled the Mac app from the OpenAI website.
Signed out and back in.
Verified macOS date/time settings.
Confirmed no VPN or firewall issue.
Confirmed my Plus subscription is active.
This appears to be specific to the Mac desktop app after the ChatGPT/Codex migration.
Could you please investigate whether this is a known issue or advise on a workaround?
I’m having this exact problem too! Very annoying, considering my Pro subscription. Kindly fix asap. The best way is to just have Codex app and ChatGPT app maybe?
No that didn’t work for me, as I believe i caught the issues as they were developing and caught the ongoing fixes and patches. Now I’ve got the Codex Icon for Chat and the default screen is Codex with only Chat opening in a pop-up. I am a Plus user though. ChatGPT classic would not even allow login.
This is the issue. It will install and let you believe you installed over the old but they are both there. Delete classic or not but open the other one.
