I installed the latest version of xcode beta thinking that would fix it... Didn't seem to work.

As the new release of Homebrew is disabling SHA1-Use, I can't even call the remove-procedure for homebrew-quartz!

$ brew remove cairo-quartz

Error: Calling Formula.sha1 is disabled!
Use Formula.sha256 instead.
/usr/local/Homebrew/Library/Taps/acornejo/homebrew-quartz/cairo-quartz.rb:6:in `<class:CairoQuartz>'
Please report this to the acornejo/quartz tap!

That's very annoying, I will report this also to the brew developer team...
