Warning: this hard locked my MBP. More detail after I’m back at my machine.Edit: System detailsRetina Mid-2015 15" - MJLT2LL/A - MacBookPro11,5 - A1398 - 2910Firefox 65.0.1 (64-bit)The hang occurred when running the benchmark with Texture Mode enabled. The spinning gear froze after a few seconds, then the display went black and the fan was maxed.It was a pain in the ass to recover: my only option seemed to be to power down and power back up again, at which point OSX helpfully remembered the state my machine was in and dropped me back into the blacked-out display and maxed fan. Some combination of NVRAM reset, SPC reset and safe mode was required to get back in.
