Hi

on one machine I use to run Hatari on Linux, the cpu is an "old" 
athlon64 from 8 years or so, and I have no problem running in stf/ste 
mode with no sound degradation and cycle exact mode.

So, I don't think it's a cpu performance issue, more an OSX SDL2 / 32 
bit issue ; maybe Troed will be able to send a different version next 
week end if he has time and it will work better under 32 bit.

Let's say we just provide an OSX 32 bit version "as is" with no 
guarantee, we can add to the readme inside the osx archive that problem 
has been encountered under 32 bit + SDL2 and that result might vary.

If it works for some people, why not ; but if there's really only 
outdated mac in 32 bit, then as you say we could stop bothering with it 
and only provide a 64 bit binary.
