Yes and no... the relevant bit is "<font size="2"><span style="font-size:11pt">Kernel trap at 0xffffff80195e7090, type 6=invalid opcode</span></font>". So probably an unsupported instruction. But unfortunately Apple does not log the opcode bytes at the faulting
location, so it's anyone's guess what the instruction might be.</div>

The simulator probably needs some instruction set extension but your guess is as good as mine as to which of the more of a dozen of the recent ones it might be.</div>

<div class="PlainText">Hi,<br>
<br>
Is anyone able to decode this crash dump from MacOS?<br>
<br>
It is 100% reproducable and happens when I start the IPAD simulator as <br>
part of the freely available XCODE package.<br>
<br>
I would be so happy to virtualize may MacOS APP development and if <br>
someone has any advice about this one, I'll happily try out stuff:<br>
