Hi! We've received reports that git-gui is showing black windows upon upgrading to MacOS Monterey. It seems to be the same issue as [1], but somehow it's only appeared for our users on Monterey and not Mojave. TKFRAMEWORK = /Library/Frameworks/Tk.framework/Resources/Wish.app * Github Issue https://github.com/Homebrew/homebrew-core/issues/39987 * git-gui formula https://formulae.brew.sh/formula/git-gui $ brew install tcl-tk $ PATH=/usr/local/opt/tcl-tk/bin:$PATH # This contains wish $ cd /path/to/git/git-gui/ $ ./git-gui.sh [1] https://github.com/prati0100/git-gui/issues/48 That said, Homebrew seems to have worked around this problem altogether by including their own Tcl/Tk dependency. I dug a little deeper and I was able to fix the theming issues by using a different version of wish: Note that I had to call git-gui.sh because that's the only entrypoint that doesn't use the system Wish referenced in the Makefile. Is this a fix that we should make in the git-gui project?
