Hi, and thanks for the fast reply!
I have read your tutorial, which is great and very understandable, but I can not get hold off the HexMiner. It is absent at App Store in Sweden. And I can't seem to get it on the Net either. So I downloaded iHex and payed 5 dollars. But it does not look as the fine image you provided. I am a Oral and Maxillofacial Surgeon with a great interest in computers but this leaves me with a big uncertainty, when the screen does not correspond. I do read and can follow instructions. Sorry!! This might not be for me. And by the way. I read that the file should be 128K (which it is in Windows 10) but when I drag it over to the Mac it turns out to be 131K.
But still, thanks h9826790!
Best regards
