My MBP late 2008 now thinks it is a MBA! It took a MBA firmware update by mistake. Now ML will not boot but SL works but with a twist. Only works with external monitor and fans works on Max. My SMC version is 1.66f4 which does not exist in Apple's releases. Now you hear it first here, how to update smc version to the 1.33f4 ? The SSD has to come off as it is ML only, hdd is still SL. Annoying and shows the weakness of the firmware update process.
