Hi folks, I'm having some frustrating issues following a shutdown a few days back and haven't been able to boot since then.
I was up and running, successfully installed El Capitan plus nvidia web drivers, my DAW software, plugins etc etc and was a very happy user. I'd even managed a few successful reboots without issue. Then I shut down the machine a few nights ago and haven't been able to boot since. I've been scouring forums ever since trying various actions I've found to try and resurrect the beast.
The error I get when booting in verbose mode is "Cannot allocate runtime error" and I haven't been able to get past it.
I've downloaded and installed a new boot USB using Unibeast 6.2.0 and while Clover boots fine, I can't get any further, no matter which boot disk I choose. I've tried 3 different version of Clover and am now using the latest from their site.
I have tried the three various SIP settings in config on the boot USB (none, 0x3, 0x67) to no avail.
I have tried both versions (and none) of OsxAptioFix2Drv and OsxAptioFixDrv. When I try to boot from OsxAptioFix2Drv it gets slightly further than the older version, but still no go.
I have tried booting from every USB port on my board and case. Also tried various HFS drivers.
I'm guessing it's something to do with my UEFI settings but I'm tried so many combinations now I've almost lost track of where I'm at.
I'm running an Asus Z170 Sabertooth Mark 1 mobo, Skylake i7 6700K 4.0GHz, Gigabyte N960OC GTX960 graphics, 64GB of Crucial Ballistic Sport RAM, Samsung m.2 950 Pro SSD in PCIe mode, Corsair RM650i, Noctua NH-U12S cooling and I have the Asus thunderbolt card installed.
Removing the GPU and thunderbolt cards make no difference to the boot error. I have multiple boot disks installed, but even with everything unplugged except the m.2 SSD I can't get anywhere.
I usually set my UEFI settings as follows (which worked originally):
Load optimised defaults, make sure vt-d is disabled, choose PCIe as default video device, USB legacy mode off,
XHCI Hand-Off Enabled, Keyboard and Mouse Simulator Disabled, point thunderbolt card at correct PCIe slot.
I make sure secure boot type is "other OS", secure boot state is disabled and keys are unloaded.
I have tried both CSM on and off, and the only difference I've noticed so far is that the resolution is better with it off.
When I disable CSM, it warns that I need the microsoft signed UEFI driver on each drive I wish to boot from. I'm not sure I have that...
I have tried many, many boot flags - but when I copy the boot backup EFI to my USB which was working previously, it gets no further. That's why I'm suspecting UEFI settings.
I have found that some settings are tending to revert themselves occasionally which I manually reset back, but there must be one elusive one I'm missing...
I'm pretty sure I've worked through everything listed in the http://www.tonymacx86.com/threads/big-list-of-solutions-for-el-capitan-install-problems.173991/
However, I'm not sure how to clear the kernel cache without being able to boot into anything except Clover.
I haven't found a DSDT.aml or SSDT.aml for my board yet. I also haven't tried a USB2 stick as Unibeast continually failed when trying to create it.
Any help or further pointers would be greatly appreciated!
Many thanks.
