hello.im coming from gnu/linux world, where MCE interrupts can be seen with mcelog and mce related tools. MCEs are usefull to check for bad hardware, to check overclock fails, test bad memorys, ... they are logged in /var/log/... like an usual log. very useful, because most of those fails are not noticeable, till things became more unstable. its a way to see internal hardware problems. obviously the worst mce mean system panic. but before this happen, mcelog is here to tell you that something is wrong.

i was wondering about how OSX treats MCE interrupts: if they are handled, if it just shows a kernel panic (like a windows bsod), if they are just loggeg.
thanks in advance.

It shows like a regular kernel panic. If you forum search "machine check" you can find several examples.

If you want to get hardcore you could look into something like this from Hackintosh godfather David Elliott:

Not what you want but I thought it was a pretty cool idea:
