atvclient at 100% cpu on mac mini

I have finally got Embedded 1.8 to boot on a very old mac mini (2006) upgraded to a Core 2 Duo CPU, 32 bit EFI but 64 bit kernel.
I always had OpenPHT running in OSX but I am now unable to upgrade OpenPHT as I am stuck on OSX 10.6, so I decided to try to install the embedded version.

I am running as “live” (not installed) for testing purposes, my remote is not working, even with a standard FLIR remote. Not only that but atvclient is also stuck on 100% cpu. I am monitoring plexhometheater.log but nothing is shown when I press remote buttons.

Any idea? Tx
