May I propose an advanced client option to disable and/or force on AVX_2, AVX and SSE processing? Such an option could be used to test if the M1 could emulate fast enough to be useful, and it might also be a good debugging option for those who are wondering if there's something wrong with the AVX processing.

I have a new M1 MacBook Air and the latest client 7.6.21 wouldn't launch but I tried using 7.6.13 as others have suggested and it has been running fine for about 10 minutes so far. PPD started at around 45000 but is now around 22000, likely due to the passive only cooling for the Air. A MacBook Pro or mac Mini will likely have better sustained PPD.

Since the M1 has four high-speed Cores and 4 low-power cores, how would that impact inter-process communications between the CPU Core threads? Would that cause time-outs in processing, or does Rosetta 2 hide those details from the program being run?

Well, running the Intel F@H on my new M1 Mac Mini, it runs through Rosetta 2 with 8 threads, and runs faster (in Estimated PPD) than the Core i9-9880H in my 2019 MacBook Pro using 16 threads.

Over the last week, I've been averaging 60,000-70,000 PPD on the M1. My Core i9 is averaging 30,000-50,000.

Because of the way Rosetta 2 "translates" code ahead of time to native code then runs the native code, rather than conventional run-time emulation, that should be pretty close to native performance. (Other benchmarks show a ~5% performance hit using Rosetta 2.)

It would be nice to have F@H aware of high-speed vs. low-power, and only run on the high-speed. And, of course, running on the GPU would be great, but that would be rather significantly more work.

Almost the same issue on some Boinc projects.
It seems to start the WU on the performance cores (in which the program works), but then tries to offload the WUs to the higher efficiency cores, at which it can't process the data.
On Boinc for Android, you can only select the amount of low performance cores. If your device has 2 or 4 high performance cores, they're only used to load the program, and cause projects that aren't written for Cortex A50 series cores to work, to freeze...
