Question

My macbook has had a kernel attack and is stuck at the apple loafing screen with the loading bar half way

Yesterday evening i was browsing as always when suddenly my macbook shut down. When restarted it showed the kernel panic screen: "your computer has a problem and it restarted itself". Online troubleshooting is for macs able to restarted themselves after a kernel panic but mine is stuck at the loading screen. I did not install new programs and I did not do anything unusual with it before the panic.

MacBook Pro, OS X Yosemite (10.10.2), Not Sure about software version

Boot into the recovery partition.

from the 4 option menu select Disk Utility.

Run Disk Utility>First Aid, Verify and Repair.

If the disk cannot be repaired, it will have to be replaced.

Ok, I accessed disk utility and after my macbook collected the disk info i looked for first aid. Didnt find it and clicked on verify. It now asks which image I want to verify. Is this correct? Sorry for being pushy but right now I feel like a monkey driving a space ship.

Read the directions in the link I provided.

Or you can start the MBP with the OPTION key held down. That should result in a display showing two HDD icons. Select the one on the right, the RECOVERY partition.

Check to see if there is a kernel panic report available. If so post it:

Run an Apple Hardware Test:

Note that an error free AHT is not definitive.

What is the EXACT model/year MBP that you have? If you do not know for certain, on the bottom of the MBP is the serial number. Enter it here:

See if OPTION + D keys will start the Apple Hardware Test.

I have a 13 inch mid 2009 macbook pro. I tried both D and Option+D, they both get ignored and the mac starts up as usual, only to get blocked on the loading screen. By the way, at this point my macbook has stopped incurring in a kernel problem i think, since it hasnt given me anymore the kernel page, it just fails to load to start.

Knowing now that you have an older MBP, the Apple Hardware test can be run from the original install disk that came with the MBP. It will have the AHT instructions on it.

Try these steps:

Reset the SMC and the NVRAM:

Then try a safe boot:

Ant success?

Did what you say and resetted SMC and NVRAM. Now tho it doesnt restart in safe mode, again it gets blocked in loading screen. I am pressing at the right time because NVRAM did have the mac restart twice as it is supposed to, so why doesnt my mac enter safe mode while I press shift? At this point Im going to wait for the battery to completely discharge and them try it again

That will have no positive affect on your MBPs performance.

Were you able to run the Apple Hardware Test using the appropriate original installation disk?

If you cannot get the MBP to safe boot, that suggests a hardware problem.
