I get receiving errors on the network adapter (checked with Network Utility) on my new iMac on startup/wakeup, not many, 1-15. I have pushed my Internet-conncetion to the max (100 Mbit) and the maxed my internal connections to my NAS with 400 Mbit without any errors so I guess it´s ok. Anyone else who noticed this? With my old Mac Pro I never got this errors, same cable, same router.
