Hi all

I have also recognised on my AMD machine this issue, however not on my Intel machine. After several hours of searching the internet I suppose it should have something to do with Code Signing! If there is not a recognised Intel processor mail.app won't be code signed and key chain ignore this application as an trusted one. Therefore it don't grant access to the key within the key chain.

I'm not an expert, so I also would be grateful, if someone could go further on my hint. Here are some links, I've found:

I hope, it is allowed to post links. Otherwise, mod delete and sorry!

Thanks, Televisor
