<< Solved >> Problems booting High Sierra after system modification

[spacebwoy]

Hi folks,

So I've been running a hack for years now, all was well until...

I'd been trying to get my 560Ti (using an 8800GTS while not trying this) to work with 10.13 for a while with no success, spotted someone who advised to disable metal by:

sudo defaults write /Library/Preferences/com.apple.CoreDisplay useMetal -boolean no
sudo defaults write /Library/Preferences/com.apple.CoreDisplay useIOP -boolean no

then use the ngfxgl=1 in clover.

I did this and whereas the machine would previously give me the spinner and mouse pointer, it now reboots as the progress bar hits the end.
So I swapped back to my trusty 8800GTS but still the same problem.

Booted in verbose mode, there's a panic before the reboot that is too fast for me to catch on video, and if I disable reboot on panic, the useful info is already off the screen.

So it will boot in safe mode, (with 8800) but not with NV_DISABLE.
I tried rebuilding and deleting the cache, but to no avail.

Tried booting without nvinject, without injected kexts...

Any Ideas?
