Based on what you wrote above I thought you had binary memory dumps.
Those are a pain to work with. I must have missed the you mentioned the
XML output.

I'll ask Jef to do that - it's his baby :-)
And frankly I have never tried to use it on a Mac.

UDDF you should be able to import into Subsurface.
So please try that. If it fails, send a test file to the mailing list
(so that Miika can look at it)

Interesting. I'll have to try it (as I have a supported Mares computer
as my backup computer...)
