Read all of the posts on here before downloading the Combo update, done a full carbon copy cloner backup to another drive, updated clover, rebooted to ensure that was working ok. and then did a time machine backup, removed the osxaptiodrvfix-64 from sufi drivers in clover folder, and replaced it with the osxaptiodrv2fix-64, repaired disk permissions and rebuilt kext cache.
I removed the Nvidia Drivers and rebooted to see if all was ok before installing the Combo update. after it installs and reboots i cannot get past first second or so off boot, I've ensured i use nv_disable=1 in clover arguments, I've tried verbose, verbose and single user mode, tied disabling caches and kexts.. and even booting from my osx/clover install usb. nothing works.
I am getting similar results to a few others on here, it seems to be about the osxaptiodrvfix (i already have replaced v1 with v2) as i get a error message about error allocating 0x11d31 pages at 0x0XXXX alloc type 2, couldn't allocate runtime area.
Hardware wise its a pair of samsung evo 850s, 2 x GTX 970, Skylake i5 6600k and Gigabyte GA170X-UD5 TH. Latest version of non beta bios and latest clover.
I really don't want to be re-installing this all from scratch again. anybody got any ideas? none I've read thus far other that the replace v1 with v2 usbaptiodrvfix seem that relevant. and I've already done this with no luck.
