Resetting the SMC every time the machine is turned off is the only way to turn it back on and when it is on the fans run at max speed etc. etc. (SMC issues).
- Have tried to swap out HDD and RAM. Software is current at Mavericks will all updates installed.
- Have tried to manually reinstall the SMC firmware but the system says that is not needed or something to that effect.
Anyone have any ideas what this could be or how I can install the SMC file anyways (bypassing the error that it isn't needed)?
