I have quite a few of my old Absynth presets from my old Mac and I downloaded Absynth again on my Mac Studio, it plays and works fine. I tried to import the old presets but they don't show whatsoever.
I went too Absynth 5 File>Options>Browser>select the relevant folder Add> Rebuild DB
I also tried copying them to the User>Documents>Native Instruments>Absynth 5>and pasting them into the Sounds folder there as well (this worked with Massive).
Thanks
