Problem using external screen and KVM switch since OSX 10.6.4 update
I've just returned from a trip during which I installed the OSX SL 10.6.4 update on my 13" MacBook Unibody Aluminium (late 2008).
It's been working fine but when I came home and plugged it into my KVM setup my mac could not find the external display. I tried rebooting and reconnecting without any success. The KVM is a Aten CS62DU USB and DVI model. It works great for my PC which is connected to the second input.
Furthermore I've connected the display using only the minidisplay->DVI adapter and a standard DVI cable. This works but not as rigid as it used to. It takes a few connects and disconnects before OSX is able to find the external screen. It seems that the timelimit for handshaking with extrenal screens have been decreased with the 10.6.4 display driver update. Perhaps this is the cause of my problem.
Have anyone experienced something simular since the 10.6.4 update? I really need to get my mac working with my KVM again.
