All right, and yes. I just had to get past the MacOS security but that wasn't hard. Since updating the EAF, I have had some other problems, though, so far, not a runaway focusing situation. Now though, nearly every time auto focus is initiated by the AIR for a 2 degree temp change, the EAF freezes, disconnects and I have to restart the AIR to even get beyond this. I have restored the AIR firmware and brought back up to latest release, and it may be all right now, but now my 2600MC has had to be sent in for a problem, so my options to test are limited to my planetary cam. Thank you for your assistance in the firmware issue!
