(I just downloaded beta3 and then 10 minutes later I see beta4 announced!) Anyway, it seems that sound is still broken on an iMac G5 for the beta3 release. The install goes through easily enough, but I learnt from last time that I needed to deselect sound in the hardware config towards the end so I tried that again. This time the machine locks up when I try to deselect sound so I'm stuck. If I leave sound enabled the machine will be useless after the install and when I try to disable sound the machine locks up! (It locks up when I select the drop down list box (in the hardware configuration screen) intending to deselect sound) I think I read on the linux ppc64 list that sound on G5 might be fixed recently so maybe a newer kernel for the install disks might do the trick? regards, Chris
