Mosaico email images not showing up on Apple Mail

[viccenteno]

I have been dumbfounded on why I only get the "question mark in a blue box" placeholder for my images in Apple Mail when I use Mosaico. If I open it in say, Gmail, it is fine, but not in Apple Mail. Also, if I use the traditional CiviMail message template, I don't get this problem.

Does it happens if you send yourself a test using mosaico.io live demo?
