OK the history with this is that a few years ago I first tried to install OSX on this mobo (H87N-WIFI) using integrated graphics. I couldn't get it to work no matter what I tried. Then I bought and installed the NVIDIA Geforce GTX650 and things abruptly went pretty smoothly and have been very good for years running Mavericks then Yosemite. My recent attempts to install first ElCapitan and more recently Sierra have been dismal failures despite many many hours of reading and trial and error. Then I thought, well I never did get the integrated graphics to work so I'll have another stab at that. Success - using new versions of Clover and playing around for a while it works perfectly in Yosemite. I even got cocky and began to plan using the GFX card in another build - after I'd finally got Sierra installed that is.
So banging my head against a brick wall, multiple Clover config.plist permutations and multiple guides followed with various different UEFI-64 drivers tried, I finally realised that some people seem to be suggesting that making the BIOS "load optimised defaults" prior to resetting them to those recommended was a standard part of their installation procedure. Now whether it really is or whether they are just making sure that the BIOS is good to go, I've no idea. What I do know is that an hour ago I had a perfectly working Yosemite install (and cloned back up) and that since I reset the BIOS to "load optimised settings" (its F8 btw) and then went on to disable things like:
BIOS Settings (Sanity Check)
Importantly of course I have my Initial Display Output set to Intel GFX. (The PCIe slot has the recommended TPLink WIFI card now) and then 64M and Max unlike the above. But otherwise I have checked and triple checked the BIOS settings and I'm totally confused. If anyone can make any suggestions? For e.g.
1) Is it worth trying to update the BIOS to F9? Would that be likely to make updating the OS to Sierra any easier?
2) Do BIOS become corrupted? I understand this MOBO has some sort of dual BIOS but I really don't know what that means to me in this situation?
3) Should I just give in and stick the GTX650 back in?
Thanks for reading all this. I will post again regarding installation difficulties in the relevant forum, I just want to get back to where I started an hour ago for the time being.
