### Environment Variable Synchronization (Essential for macOS users)
On macOS, GUI applications (launched from the Finder, Dock, or Spotlight) do not inherit the user's shell environment variables by default. This often causes errors where Emacs cannot find external tools like `git`, `grep`, `pip`, or language servers (LSP), even if they work perfectly in your terminal.
To fix this, add `exec-path-from-shell` to `~/.emacs.d/post-init.el`:
```elisp
(use-package exec-path-from-shell
:if (and (display-graphic-p)
(eq system-type 'darwin)) ; macOS only
:ensure t
:demand t
:functions exec-path-from-shell-initialize
:config
(dolist (var '("TMPDIR" "SSH_AUTH_SOCK" "SSH_AGENT_PID" "GPG_AGENT_INFO"
"LANG" "LC_CTYPE" "VIRTUAL_ENV"))
(add-to-list 'exec-path-from-shell-variables var))
(exec-path-from-shell-initialize))
```
