Hello everybody. [br]
I have tried to update my Macbook to Sierra as it was running a bit slot lately (the laptop is used mainly for movies, nothing too serious). After I got the error saying that it wasn’t possible to install the software, I tried to reinstall the OS from recovery mode. After a couple of times I got the PPM002 Error. Besides this, it only starts if I press and hold the power button until the Start Sound finishes. I know that this error has to do with the build in memory but is there anything that can solve it or do I have to replace the logicboard? [br]
thank yoou.
