我有一台 mac mini M1，运行 macos 12.1、emacs（27.2 build 3），带有 auctex 13.0.14（elpa 包）和 Skim 1.6.6。
问题：emacs 中的 Cc Cc 可以编译，但无法将 Skim 作为查看器启动。正向搜索 Cc Cv 不起作用。Skim 上的反向搜索（command-Shift-right click）可以工作。
这是我的.emacs 文件：
(require 'tex-site)
(setq ns-pop-up-frames 'nil)
(set-face-attribute 'mode-line nil :height 187)
(setq TeX-auto-save t)
(setq TeX-parse-self t)
(setq-default TeX-master nil)
(add-hook 'LaTeX-mode-hook 'visual-line-mode)
;(add-hook 'LaTeX-mode-hook 'flyspell-mode)
(add-hook 'LaTeX-mode-hook 'LaTeX-math-mode)
(add-hook 'LaTeX-mode-hook 'turn-on-reftex)
(setq reftex-plug-into-AUCTeX t)
(setq TeX-PDF-mode t)
;; Use Skim as viewer, enable source <-> PDF sync
;; make latexmk available via C-c C-c
;; Note: SyncTeX is setup via ~/.latexmkrc (see below)
(add-hook 'LaTeX-mode-hook (lambda ()
(push
'("latexmk" "latexmk -pdf %s" TeX-run-TeX nil t
:help "Run latexmk on file")
TeX-command-list)))
(add-hook 'TeX-mode-hook '(lambda () (setq TeX-command-default "latexmk")))
;; use Skim as default pdf viewer
;; Skim's displayline is used for forward search (from .tex to .pdf)
;; option -b highlights the current line; option -g opens Skim in the background
(setq TeX-view-program-selection '((output-pdf "PDF Viewer")))
(setq TeX-view-program-list
'(("PDF Viewer" "/Applications/Skim.app/Contents/SharedSupport/displayline -b -g %n %o %b")))
(custom-set-variables

;; Your init file should contain only one such instance.

我刚刚将 macos 从 12.01 更新到 12.1。
知道哪里出了问题吗？
