I recently upgraded my iMac OS to Big Sur (11.2). Since then, the wake on LAN does not seem to work for Roon. The core is running on the iMac (3.6 GHz 10-Core Intel Core i9). I use an iPad mini, iPad Pro and an iPhone to play back on Sonos hardware or on a DCS Bartok. Nothing else changed. It used to work fine before the OS upgrade. Network is switched Gig Ethernet and a ERO Pro6 mesh wifi network.
