Now the following comments only pertain to my mid-2011 21.5 inch i5 2.5ghz iMac which I purchased. It had an OEM hard drive failure that had occurred and I put a Samsung 850 pro SSD inside the iMac with a OWC thermal cable bypass to keep the fans from blaring at 6500 RPM. The previous owner was trying to update the old hard drive to 10.7.5 and the installation failed so he erased the hard drive try to reinstall 10.7.5 as a raw install not knowing that it need a 10.6.7. So I have been troubleshooting this iMac since and I will list the steps below.
-
-I ended up ordering a gray OEM Apple iMac mid 2011 OS X 10.6.7 bootable installer disc off eBay for 10.00$. Awaiting the arrival of this disk (4-19) to wipe the hard drive with zero pass and reinstall the OS X via the SuperDrive. I believe the issue is in the Systems/library/Cache ktext startup files/folder and/or the SMC. There is no way to reinstall or hard force a EFI Update to version 1.9 (Apple support website) for the mid 2011 IMAC, so all the drivers and SMC extensions it originally came installed with are on a model/year specific OEM apple disk. I will post a link from the buyer are used on eBay. Thanks Apple, once I have this issue resolved I will come back and update to let you know whether or not this process or last resort worked.
Now I have done the FSCHK disk dev0s2 in single-user mode three pass. I have also done all verify disc and repair permissions. I have reinstalled and ran OS X update for OS X 10.6/10.6.6/10.6.7/10.6.8 and 10.7.5 and none of the OS X installers carry the correct boot.efi, smc, or startup cache file extensions. I have remove the hard drive internally and installed it externally and via FireWire (target-disk mode) on two other MacBooks (white OS X 10.6.8 installed natively)(2013 MB Pro i7) I own and was able to do a start up boot on the white MacBook due to the close proximity of the Operating systems.
I have done multiple NVRAM and SMC resets, to no availabity “nothing changes”, I also went into terminal to via target disk mode on the iMac SSD and changed commands to cause the iMac hard drive to only startup via verbose mode every time, but that didn’t work either, not without holding command-V.
