[Message part 3 (text/plain, inline)]

Hi,

I am using the precompiled version from https://emacsformacosx.com/builds 

https://emacsformacosx.com/emacs-builds/Emacs-2024-09-11_00-09-10-69e1aca041c57ba425425d31471e1c8f86d3bf04-universal.dmg

I have chosen the latest Emacs 30 version. The min configuration is as follows:

(add-to-list 'treesit-extra-load-path (expand-file-name "tree-sitter/" user-emacs-directory))

(require 'clojure-ts-mode) 
 ;; debug 
(setq debug-on-quit t)

and I only use clojure-ts-mode package

cd ~/.emacs.d/site-lisp
git clone https://github.com/clojure-emacs/clojure-ts-mode.git
