Codex Desktop: “Open in…” takes 3–5 seconds to open file references in JetBrains IDEs on one Mac

What version of the Codex App are you using (From “About Codex” dialog)?

26.727.40816

What subscription do you have?

Plus

What platform is your computer?

macOS 26.5.2 (25F84), Darwin 25.5.0, arm64 MacBook Pro (Mac16,1) Apple M4 10-core CPU 10-core GPU 24 GB memory

What issue are you seeing?

When I open a local file reference from a Codex Desktop conversation by right-clicking it and selecting a JetBrains IDE from the “Open in…” menu, there is a consistent delay of approximately 3–5 seconds before the requested file opens or the IDE becomes focused.

The affected applications I tested are:

  • IntelliJ IDEA
  • PyCharm
  • GoLand

The file eventually opens correctly, and Codex does not display an error. However, the delay is noticeable and occurs repeatedly.

Opening the same file references through the following targets feels immediate or reasonably fast:

  • Antigravity
  • Finder
  • Terminal

The common factor among the slower targets is that they are all JetBrains products.

This report is not about the normal left-click behavior. A normal click opens the built-in file preview in the Codex side pane, which appears to be the intended product behavior even when an external editor is configured.

The issue specifically concerns the context-menu workflow:

  1. Right-click a file reference in a Codex conversation.
  2. Select a JetBrains IDE from the “Open in…” menu.
  3. Wait approximately 3–5 seconds before the file opens or the IDE receives focus.

What steps can reproduce the bug?

  1. Open a local project in Codex Desktop on the affected Mac.
  2. Open a conversation containing a reference to a local project file.
  3. Right-click the file reference.
  4. Select “Open in…” and choose IntelliJ IDEA, PyCharm, or GoLand.
  5. Observe the delay between selecting the application and the file being opened or focused.
  6. Repeat the same operation with Antigravity, Finder, or Terminal for comparison.

Actual result:

  • JetBrains IDEs usually take approximately 3–5 seconds to respond.
  • Antigravity, Finder, and Terminal respond almost immediately.
  • The requested file eventually opens correctly.
  • No error message is displayed.

The behavior is reproducible on one MacBook Pro, but not on two other Macs that I tested.

What is the expected behavior?

Selecting a running JetBrains IDE from the “Open in…” context menu should open or focus the requested file without a noticeable multi-second delay.

The response time should be comparable to other supported targets such as Antigravity, Finder, or Terminal.

When the target IDE is already running, the requested file should ideally open or receive focus within approximately one second.

Additional information

I tested the same workflow on three Macs:

| Device | macOS | Codex App | Result |
|---|---|---|---|
| Mac mini (Mac14,3), Apple M2, 24 GB | macOS 26.1 (25B78) | 26.715.21425 | No noticeable delay |
| MacBook Pro (Mac16,1), Apple M4, 24 GB | macOS 26.5.2 (25F84) | 26.727.40816 | Reproducible 3–5 second delay |
| MacBook Air (Mac17,3), Apple M5, 16 GB | macOS 26.5.2 (25F84) | 26.727.40816 | No noticeable delay |

The MacBook Pro and MacBook Air are running the same macOS and Codex App versions, but only the MacBook Pro reproduces the delay.

This suggests that the behavior is environment-specific and is not caused solely by the macOS version or Codex App version.

The issue was already present before I upgraded the affected Mac to Codex App version 26.727.40816. I do not know the exact first affected version, but I remember experiencing it while builds at or before approximately 26.715.21425 were current.

Additional observations:

  • The delay occurs with IntelliJ IDEA, PyCharm, and GoLand.
  • Non-JetBrains targets tested on the same machine are significantly faster.
  • The requested file eventually opens at the correct location.
  • No visible error is shown.
  • The normal left-click behavior that opens the Codex side-panel preview is not part of this report.
  • The exact environmental difference between the affected and unaffected Macs has not yet been identified.

JetBrains versions:

  • IntelliJ IDEA: 2025.3.6
  • PyCharm: 2025.3.6
  • GoLand: 2025.3.5

Test conditions:

  • JetBrains IDE already running: YES
