Running 10.4.11 on QS powermac. I was using this as a file server but noticed that it would disappear from my MBP10.11.6's finder. I noticed that when my Cinema display turns off or the powermac's screen saver turns on - this is when sharing stops and it disappears from my MBP finder window. Anyone know how to fix this aside from never allowing the SS to start or the display from going to sleep? Thanks!
