Description

I'm experiencing frequent hangs while using Codex Desktop for real development work.

The issue is intermittent but happens multiple times per day.

Instead of completing the task or returning an error, Codex simply stops making progress.

Typical scenarios

The hang usually happens while Codex is using tools, for example:

• apply_patch
• opening or reading files
• opening generated images
• browser interactions
• editing multiple files

Sometimes the last visible message is something like:

"Now I'm going to open the generated image..."

and then nothing happens for several minutes.

Other times it hangs during file edits.

Expected behavior

Either:

• complete the tool action,
• retry automatically,
• or return an error explaining what failed.

Actual behavior

Codex appears to stall indefinitely.

There is no visible error.

No additional output is produced.

The only option is to stop the task and start again.

Restarting the task usually works temporarily.

Frequency

Several times per day.

Mostly during larger or multi-step tasks.

Additional notes

This seems similar to other reports involving apply_patch and long-running tool execution on macOS.

The problem is not specific to one repository.

It has happened across multiple projects.
