mmm, I think this is just a release configuration issue, supported archs option here must be set to x86_64

[dalexsoto]

mmm never mind, I double-checked the configuration and seems to be this way already

[GouriKumari]

I did check that supported architecture is already set to x86_64, https://github.com/olegoid/SubmissionSamples/blob/master/MacCoolApp/MacCoolApp/MacCoolApp.csproj#L53

[dalexsoto]

I cannot seem to repro with current master let me test with d-15

[dalexsoto]

Ahh it seems it is not the main executable, sorry I should have reviewed the error message more carefully, the culprit is libMonoPosixHelper.dylib

[dalexsoto]

It seems we need to remove any other 32 bits from helper libs too, not just the main executable.

/cc @chamons

We might have to strip libMonoPosixHelper.dylib in release configurations...
