Hello,
         First off i'm using a Macbook Pro 13-inch 2017.  The specs are on the image.
I was having problems with Tails 3.16, and your support suggested that I try the 4.0 beta.  Downloaded and installed through a VM, and Mac can see the USB, either through rEFInd or boot menu, same as 3.16.  But can't get anything to show up - no Tails boot menu, just a black screen, same as 3.16.  I can't add anything to the boot options because it hasn't appeared.  The Tails boots fine on another PC so it's a problem with the Mac.
Just wondered if there will be a fix for this by October 22nd, when 4.0 is released? Or any current workarounds for this problem.  If not, thought it'd be useful for you to know, so hopefully I can get it working.
Thanks, Clement.
