This is my report on 10.2.4 and the coma problem. Prior to my 800mhz upgrade I had no cube sleep or coma problems. I used OS X up to 10.2.2 After I upgraded to the 800Mhz board I immediately experienced the coma(lights and fan start up but no wake at all). With 10.2.3 and even yesterday with 10.2.4 same deal - coma. 10.2.2 10.2.3 10.2.4 w. 450Mhz OK ? ? w. 800 Mhz Coma Coma No Coma * *Out of desperation (and jealousy!), I did a total reformat and partition of my Seagate 80mb drive and started from scratch. To my surprise - I now have no coma problems (OS 10.2.4). I am completely without explanation as to why? So there is my 0.02€ worth Simon
