OCLP is excellent but it's all coming to an end for Intel Macs unfortunately. Even Homebrew just dropped the ball a few days ago (this is the final draw for me, I'll keep a Sequoia partition but my MBP2015 daily drives on NixOS + GNOME)

Yes. If anyone reads this in the future: you need to clone the brew repo and use v7.0.2 and install it manually.
