I'm investigating a bug report about Racket Mode's Emacs front end being unable to talk to its Racket back end. But it turns out Emacs isn't a necessary ingredient? It appears [there might be an issue with its Racket back end on macOS Sequoia](https://github.com/greghendershott/racket-mode/issues/722#issuecomment-2371215759). Almost as if it were some issue with Racket itself on Sequoia (as unlikely as that seems to me). I can't reproduce this on Monterrey -- and my older Macbook can't upgrade to Sequoia. I'd like to make some progress, if possible, before buying/receiving new Mac hardware. 👉 Do you have Racket 8.14 and macOS Sequoia? Are you willing to `git clone` the Racket Mode code in some temp directory, and [try that quick experiment in the command line](https://github.com/greghendershott/racket-mode/issues/722#issuecomment-2371215759)? (You needn't run or even have installed Emacs.) Thanks in advance if you have 5 minutes to try this! (And my sincere apologies in advance, if the real issue is I've found a fresh way to be an idiot.) ---

I posted my results from 8.14.0.2 (same problem) and 8.14.0.4 (works). Both using an Intel mac. ---

I tried with 8.8 and 8.18 on a M4 Sequoia. It fails. I should use 8.14 ? Thanks. ---

This was solved in [Back end hangs on macOS Sequoia with Racket before 8.14.04 snapshot 2024-09-24 · Issue #722 · greghendershott/racket-mode · GitHub](https://github.com/greghendershott/racket-mode/issues/722) The conclusion is to use 8.15 or greater. Are you seeing the same issue on 8.18? ---

My mistake. 8.18 doesn't show this issue. Thanks.
