Hey guys, having this problem with my new headless server, is bought the mac mini last week and installed it while hooked on to the tv via HDMI, activated the built in remote desktop feature and disconnected all the cables. Moved the mini to its final destination and plugged only the power and network cable back in. I then tried to access it by vnc wich works perfectly but when i move my mouse around i get artifacts all over the place... Have no idea what is causing this but when a screen is attached to it the problem seems to go away... I embedded an attachment with a screenshot of the problem. Anyone knows how i solve this problem?
