Seriously cannot believe the PWM frequency is 240Hz. I was shocked out of my mind when I first saw that. It needs to be on the order of kHz to avoid eyestrain for a very significant proportion of the population. Did Apple just forget about accessibility, or did they underestimate it?

I'd be fascinated to see how common this really is. Is it something that affects .0001% of users, more, less? At Apple scale an issue like that could hit millions of people. Given the newness and expense of the product one would assume not that many OLED Macbook Pros have shipped. So it's surprising that this issue didn't come up in testing if we're talking about more than a handful of people.

I'd love for more research to be made into PWM sensitivity, if only to find out roughly how many people experience problems with it.

I've never had issues with it other than when trying to film certain old displays, but then again, I've never had issues with PAL TV sets running at 50 hz interlaced, nor even old PC CRTs running at 60, which definitely was not 'flicker-free', so I'm probably on the far end of the spectrum compared to the PWM sensitive.

It's an easy thing to forget, as with many accessibility features. And it's going to suck to have the nominally best display be one you just can't use if want to not feel like gouging your eyes out.
