Firmware problems for the latest MacBook Pro

All the users that recently bought a MacBook Pro might have noticed that every now and then, the process elaboration icon appears for 20 seconds up to a minute, without any apparent reason. In those seconds, the processor temperature rises abruptly and it’s impossible to use the computer.

THe problem seems to be with the EFI 1.7 firmware, and although Apple hasn’t yet announced any fixes, it’s likely that the problem will be solved with an update soon. In the meantime, a thread in the official Apple forums teaches how to downgrade the firmware, going from the 1.7 version to the 1.6, although the procedure could permanently damage the computer, so it’s not recommended.

It might be best to wait for Apple to release an update.
