Request #25063 has been rejected by Alad [1]: x-arc-white is the maintainer's personal fork. This one has a dead upstream. Neither have been updated since 2018. A third package, osx- arc-white-git points to a 404 repo on github. As such I would argue to delete all three. I will file deletion requests accordingly. [1] https://aur.archlinux.org/account/Alad/
