I am using the IOGear GCS634U KVM with a Mac Mini and a PC. Whenever I go from Mac to PC and stay on the PC for a bit and then go back to the Mac, I will notice that the Mac has rebooted during this time and is now in 640x480 huge resolution. I want to resolve this problem because if the Mac keeps shutting down like this it will eventually ruin my hard drive. I use a usb keyboard and mouse that are working just fine with the KVM (Cyborg Keyboard and Logitech Wireless Mouse) and have for a couple years. This issue has been going for a year or more now. I have changed to different ports on the KVM and still get the same issue. Any help is appreciated.
