Dell 9400 both cores working
krille in InsanlyMac forum discovered that both cores of a T7200 in a Dell 9400 are working if you go to sleep after boot. After the resume both cores are working !!!
I have tried and it is really working.
So far I have really no explanation what is the cause for this strange behaviour.
My OS is 10.4.9 updated with JaS ComboUpdate (thanks for the great work !!)
Kernel Netcas 15.3. (installed by the update)
So it would be important to find out the cause, hopefully it will work sometimes without going to sleep before work :-)
