Hello, 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. Use target disk mode to share files between two Mac computersUsing Disk Utility to verify or repair disks It maybe your logic board has a problem which would mean you need to replace it, if the problem is not the SSD drive.
