Forgot to say that app_config was also required last year for Mac GPUs to skip the benchmark and invoke the correct transform (OLC or OLC2). Also no longer valid.

app_config was required last year to allow multi-threading for CPU apps on Macs. That code is obsolete now and will cause failures.
version 4.01 will run without any app_config help at all.
M1 and M2 Macs will run CPU apps via rosetta without resorting to anonomous platform.
Applications for native M1 and M2 Macs are still under development. Stay tuned, as the old-timers say.

cpuGFN21 for Mac?

I didn't know it was removed for mac. where did you see that>
On the applications page, it is no longer listed (for Mac). If you sign up for it in preferences anyway, the server will give you nothing.
I guess I'll try discord when I get some time.

I cannot find any discussion regarding the removal of cpuGFN21 for Macintosh when the application went to version 3.25 last August. Will there be a Mac version available any time? If so, will it be in time for the December challenge?

The programs using OpenCL would need to switch over to Metal. Fortunately that isn't too terribly difficult.
I, for one, would like to see that. Is anyone working on it?

OK, but the second main task is still unsent a week later. I'm guessing it is stuck in some kind of limbo.

GFN-21 failing on M1 Mac
(Message 152599)
Posted 536 days ago by JH30895
This is profoundly embarrassing. My mt-3 task also failed, with messages similar to yours.
I went back to my benchmark results from Sep 27 and discovered that those successful runs were, in fact, single threaded. They ran in ~558,000 seconds, running four tasks simultaneously. (Between then and now I lost sight of that, and prepared the M1 for multitasking along with all the other machines, that are Intel.)
I apologize for leading this discussion astray, but it looks like multi-threading is not emulating well on the M1 processor.
"Using SSE4 transform (3 threads)"
"atos cannot load symbols for the file genefer_macintel64_3.3.4 for architecture x86_64.

I'm running an M1, but without the problem you describe. If I were, I would reset the project and re-install BOINC, and try again.
I have run GFN-21 tasks with 4 threads several times. They took over 5 days, but they ran successfully. For the current challenge, I am running with 3 threads in order to keep temperatures down and still finish in time. So far, so good.
If you run single threaded, be prepared to wait nearly three weeks for results.
