Short description of error
Glass shader makes object black in viewport. Happens with any distribution which is not Sharp.
Exact steps for others to reproduce the error

This #e0a1a2f49dab on an Apple MacBook Pro 13" from 2016 (running Big Sur 11.2.3 as well) with an Intel 540, not sure what you mean with Sharp though:
Sharp is the distribution in the Glass shader. The file is set up to use Beckmann.
Your viewport seems correct though. Could be something specific to Iris Plus 655 though =\
Can still confirm with the latest build from the buildbot. Both 2.93 and 3.0.0.
Just to clearly indicate what the issue is, here is a screenshot:

Running macOS with AMD graphics here. I am not seeing the issue, all good for me.

May be not a Mac related bug but more of Intel GPU.
Guess the report is similar to #88754 (Intel HD graphics: Changing Roughness Value to 0 causes mesh to be black)
Like others I am also attaching the system info :p

@Sergey: think this could be closed as duplicate of #88754 (Intel HD graphics: Changing Roughness Value to 0 causes mesh to be black) (seems so)?
@lichtwerk, Technically, we usually merge newer reports into older ones. It might be the same root cause, the newer report is about different GPU and different OS. So if you merge you need to make it clear in the report that it affects multiple hardware/OS configurations.
@Sergey Hi, can you still replicate this problem? Issue from the report #88754 has been fixed already.
Changed status from 'Needs Triage' to: 'Resolved'
It is indeed solved. Didn't realize the report is still open. Thanks for reminding.
