Similarly if you're using MacPorts, make sure to sync and upgrade xz if you have it installed.

5.6.1 was available for a few days and just rolled back ~20 minutes ago: https://github.com/macports/macports-ports/commit/a1388aee09...

Thank you for this tip. `brew upgrade xz` worked.

I was going to uninstall but it's used by so many things…

     brew uninstall xz
    Error: Refusing to uninstall /opt/homebrew/Cellar/xz/5.6.1
    because it is required by aom, composer, curl, ffmpeg, gcc, gd, ghostscript, glib, google-cloud-sdk, grc, harfbuzz, httpie, img2pdf, jbig2enc, jpeg-xl, leptonica, libarchive, libavif, libheif, libraw, libtiff, libzip, little-cms2, numpy, ocrmypdf, openblas, openjpeg, openvino, php, pillow, pipx, pngquant, poppler, python@3.11, python@3.12, rsync, tesseract, tesseract-lang, unpaper, webp, wp-cli, yt-dlp and zstd, which are currently installed.

You're welcome!

It's been reverted now: https://github.com/Homebrew/homebrew-core/blob/9a0603b474804...

Yeah it was when I posted the comment too. That's why you could type brew upgrade xz and it went back to 5.4.6 I guess? But it might have been around that time, cutting it fine, not out for everybody. I don't know. Comment race condition haha! :)
