(CPU)s failed to load


My Mac fails to load OS-X just gets stuck at the apple logo, after a lot of off/on cycles it will maybe start OS-X.

Some times during startup it will show a error log on the apple logo saying (CPU)s failed to load.

Please Help, thank you in advance!

I haven't seen this error before and I don't find anything on it anywhere are you sure the error is: (CPU)s failed to load ? Thats a very strange error call.

I would recommend seeing if you can find a friend with a Mac that you can connect to yours using Target Disk Mode to first backup anything important and also run Disk Utilities to see if your systems drive is healthy. Is this the original drive or a replacement? That maybe a factor here as well.

It maybe your logic board has a problem which would mean you need to replace it, if the problem is not the SSD drive.

I've never seen that error either. Possible virus, do you have a Windows partition on this machine?


Went to the apple store, he was saying that most likely the logic board needs replacement. Hope of coarse its something simple


Yes I head a boot-camp partition on it but after i wiped the system clean got rid of the partition and reinstalled to factory, still the same issue. Ran Health aid and pressed "D" on start up to get to diagnose screen. Every time i did that there where never any issues.


You really need to try to access from an external source like Dan mentioned or an external USB drive. I get really sick of hearing other techs or computer stores telling people they need a new logic board. 90% of the time, the logic board is not the issue. But your message has never been seen by two very experienced pros (I've been at it for 36 years and never seen this message Try starting in Safe Mode by holding down the Shift key on boot and tell (better to take picture) us your results.


Tried different methods like holding down shift, tried to reset the SVMC(i think that's what its called) hold down option, command, P & R. Tried to reset else not sure what its called when the screen is not turning on after holding down 4 buttons for 10 seconds. Another one where you have to hear the chime 2x to enter some kind of mode. Also the middle part right in front of the keyboard is getting pretty hot, didn't know that the MBP starts boot-camp in default after my battery ran out of juice and went into windows 7 sleep mode, was sitting like that for a long time till i noticed and the mac was very hot, just wondering if i fried it. The pre-owner told me that this model doesn't have a cooling fan. Sorry for the terrible description but i'm 2 months in to the mac world and still learning all the tricks.
