Eu pesquisei:
❯ brew search webkitgtk
webkitgtk was deleted from homebrew/core in commit cc9be4ac:
webkitgtk: migrate to boneyard
Repeatedly breaks/causes issues & consequently sits there stuck on
versions with publicly-known CVEs frequently.
Closes https://github.com/Homebrew/homebrew-core/issues/9053.
To show the formula before removal run:
git -C "$(brew --repo homebrew/core)" show cc9be4ac^:Formula/webkitgtk.rb
If you still use this formula consider creating your own tap:
