We've received new iMacs and MacBook Pros (which have not undergone a hardware refresh and can still run OS 10.6) and are unable to Netboot them using our existing 10.6-based NetBoot or a new 10.7-based NetBoot image created using that hardware.
The computers download the Netboot image from the server and complete the boot process (verbose boot completes) but then the system just sits there with the background image showing (10.6 shows the Casper Suite background, 10.7 shows Apple startup white screen) and a movable mouse cursor. The computers have an IP address at that point and respond to pings, but cannot be connected to via SSH.
Older hardware models in our environment boot both NetBoot images without any problem. Our NetBoot server is running 10.6.8 Server.
Anybody have any suggestions or even seen this before?
