The real story is how late this news is coming. The bar exam is in 2 weeks. ExamSoft is just now notifying examinees?

Is it really possible they do no testing in-house with newer processors? I mean, yes, of course it's possible. But keep in mind this is a company that knows that students will be forced to use their software with every configuration under the sun.

My guess is that they do a lot of testing in the cloud, on anonymous virtual servers, just like everyone these days. Could/should this have been caught?

My experience over the last few years as a COVID-era law student is that personal computer exam software is universally terrible. Probably a business opportunity here.
