Really tired of this. How can a billion-dollar company still not fix these issues or get them right?

Research direction

No source files, tests, or concrete reproduction steps are identified. Start by reproducing the model-selection, scrolling/RAM, and post-update launch or chat-loss problems on macOS 26.715.61943, using feedback ID no-active-thread-019f84d0-131b-76f2-acc5-4a34028b8076. Done would require narrowing this report to one confirmed failure with a reproducible test and defined fix.

What issue are you seeing?

ChatGPT/Classic: I still can’t select the model. This started a long time ago and has never been fixed. 4 months ago: https://www.reddit.com/r/codex/comments/1s5hyso/bug_cant_select_model_or_reasoning/ Still happening: https://www.reddit.com/r/ChatGPT/comments/1uufqk9/unable_to_change_model_alway_stays_auto/
The ChatGPT Codex macOS app really lags on a simple scrolling in a lists and uses a lot of RAM. Killing it frees 5-8Gb of RAM.
MAJOR BUG: After today’s update (ChatGPT 26.715.61943, currently the latest version), I lost all my chats, and now the app just blinks on the intro screen.
Really. WTF?

Just build it as a clean native SwiftUI app for macOS.
Honestly, I believe that would solve most of these problems.
Right now it feels like it’s built with some custom UI framework, and the result is sluggish and unreliable.
