I'm on High Sierra (10.13.6) on a Mac Pro 5,1 with a dual Hexacore 2,66GHz Xeon... meaning 24 threads, plus a RX580.

I've noticed recently that my hashrate on the CPU is pretty low. When I first tried XMR STAK, one year before, I had 300 / 350 H/S on the CPU. Now I barely got 100/130 H/S ... with xmrr stak 10.0.4 ... what do I miss ? I first thought it was because of the hard forks, but I tried on some iMac (i5 form 2011 to 2013) and they got the same rate now than they had before (100 to 160 H/S) .. meaning some dual core i5 are doing better now than my Mac Pro with 24 GB of ram and 24 Threads ?! I've noticed that, now, XMR Stak is only using 50% of the CPU power... before it was 100% ... But it may have been months, as I was too busy to notice that.

My cpu.txt file is the one generated by XMR Stak...

`"cpu_threads_conf" :
[
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 0 },
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 2 },
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 4 },
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 6 },
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 8 },
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 10 },
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 12 },
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 14 },
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 16 },
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 18 },
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 20 },
{ "low_power_mode" : false, "no_prefetch" : true, "asm" : "auto", "affine_to_cpu" : 22 },

],
`

I've tried to change prefetch and affine to cpu, that doesn't change anything. I've tried to add more threads... which only make the hashrate lower.

I've tried some video encoding, to check if my CPU got a pb... and they don't.

So, I guess there's something here in the settings, but I don't know what... can someone helps ?? Thanks you...

Weird: just to check, I've download the minergate cli... and I'm back to 320/370 H/S with the same parameters ... I don't get it.

Is there something wrong in XMR STAK with these Xeon X5650 ? Is it because of macOS ? ... I have no idea !!

as you can see, CPU mine at -/+100 H/s ... with the minergate miner, I easily got 330... and sometimes 400 H/s ... on the same machine (but no GPU on MG, of course). I tried to laucnh MG on the CPU and xmr stak on the GPU, and bingo .. 250/270 H/S on GPU plus 330 to 400 h/s on CPU. But, of course, I'm not fine with MG, I'd rather like to use XMR all the way.

doing it rite now.

aaaaaaaand that's it !!! back to 300+ H/s on CPU with xmr stak !!! nice !

would it be because it's Xeon CPU ? and no i5/i7 ... as AVX was introduced in 2008, the first mac pro can't have it, that's right but the 2010/2012 edition, they have it for sure... and it explains why I had so little success with MP1,1 to 3,1 with mining when I did some tests two years ago.

well, I can spare some time to test stuff if you want ? I got MacPro 1,1 and 5,1 ... iMac from 2010 to 2015... Retina 2012 and 2013.. some Mac minis ...
