System wont boot and SMC wont reset

System boots erratically. Most of the time when pressing power button sleep lite comes on and fans spin. Display stays dark. In this condition I have tried SMC reset - with no success.

When it does boot ( usually after sitting off overnight) it crashes to the picture shown below.

.

Is this a hardware issue?

Is this a logic board issue?

Why wont the smc reset?

Thanks

I don’t have another mac product. However using transmac I loaded High Sierra on a known good SSD. Transmac shows that the drive has a 7.3GB HSF+ partition. Thats the partition Transmac extracted High Sierra into. Does this sound right?

That doesn't make sense! That sounds like the OS image file.which won't be large enough to run the installer.

Let's see if you have an alternative. Do you have a TimeMachine backup of your system?

I do not have a TimeMachine backup. Fortunately, there are no files on the macbook that are irreplaceable. I am completely frustrated by the machines seeming inability to respond to SMC resets. It did for a time yesterday, but today no matter what reset is attempted (SMC, NVRAM, Recovery) all that happens is the sleep light comes on and the fans spin. Some I have consulted with thing this points to an logic board issue.

I have a good SSD available, what steps are necessary to image OSX on it from a Windows 10 machine. I do not have another mac.

Do you have a friend with a Mac?

The three times I tried to use TransMac I was never able to get it to work properly.

Resetting SMC won’t alter things here.

Panic crashes are hardware related either RAM or drive. Drive is the more likely issue as RAM is tested during POST, but the drives virtual RAM space is likely suspect.

I would try booting up on an external bootable drive to see if that worked. With the drive plugged in (FireWire, USB or Thunderbolt) reboot the system and press the Option (⌥) key to start up to Startup Manager, which allows you to choose other available startup disks.

Reference: Mac startup key combinations

There is likely an elephant in the room as well ;-{ Thats your drives SATA cable is likely having problems which could also be a factor here besides the drive its self. Your Hard Drive Cable Is A Ticking Time Bomb. But, before we worry able it are you able to boot up on the external drive?
