Hi there, well I tried all these things down below here and double checked my movements within the inside of the MBP and nothing disturbed I could see or looked like it shouldn’t from anything I touched. I tried booting with no RAM cards, then inserted previously used and operational RAM cards and still no change, no chime from it.
So on Thursday, with fully a fully prepared written history of the recent events with it I dropped it to a local computer repair shop one I’ve used before and they’ve advised they could not resuscitate it. Likely Mother Board fault which would be expensive they say. It is a 2011 MBP after all but I’m disappointed as it was working fine prior to my son installing this third party software. I have no proof this was the cause of the fail but it is the most likely suspect. OSX is very reliable when left to itself. In my final attempts to resurrect it, i thought I’d remove the fan altogether, very delicately. In doing that, which was very easy, i noticed the small air entry grille was quite plugged with fluff. I suspect this was causing the processor to run hot despite the fan running flat out, which in turn set Tim about trying to turn it down using his “special” third party software” as the fan noise annoyed him. So the root cause was probably the restricted air flow into the fan from fluff! Oh well, now my challenge is to locate another machine and determine how I will migrate Tim’s backup without bringing back the SMC Fan Controller software in the process. My choices, once I have a replacement machine (with High Sierra in place), are to plug the old HDD via SATA and retrieve using Migration Assistant (where I already deleted the SMC Fan Controller) and select the data to be retrieved. Important things are Photos library, iTunes and other data but not OSX related files. Is this level of selectivity something that MA allows? Any other tips in this process? Thanks for all those who chipped in with help for me in this, I really appreciate it folks.
