Can´t Sync BPM over Ableton Link to Mac

[HEKKTIK.music]

Hello!
I can't synchronise my BPM from ShowControl with Daslight on the Mac.

When I try to synchronise my BPM with Daslight via Ableton Link, it only works if Daslight is running on a Windows client.
It does not work on the Mac.... I don't know why....

I'm reading the CDJ's with Show Control on an Apple MAC. The switch from the players goes to a network adapter that receives an ARPA IP from the player.
From the MAC, a second network adapter goes to my Lighting Network Switch (no DHCP, manual IP only). And from there to my Daslight client.
