Quartz Debug. That’s a name I haven’t heard in a while.

  It's still being updated and included in the "Additional Tools for Xcode 15"[0] and is the only way to disable vsync/"Beam Sync" at the os level using Apple tooling, afaik. Beamoff[1]/beamsync.py[2] are good 3rd part solutions, though. I use my m1 mbp in clamshell mode connected to a 75hz 1920x1080 ips all day every day, so until I can buy a monitor that supports adaptive sync, the reduction in latency that disabling vsync brings is worth it to me.
