Trouble with Unarchiving .xz file

I am running macOS Sierra 10.12.3 and I am having trouble downloading the most recent Nightly Build (fae1efa). I am attempting to download the file, but once it downloads as a .xv file, I try to Unarchive it and I get a “there was a problem reading the file” prompt from The Unarchiver application. I’m not too educated when it comes to fixing these problems, but I am great at following directions. Any help is appreciated. Thanks!
