MacbookPro2018 13inch.
I have installed the latest macOS 10.15 beta8. but I failed to install driver(HighPointNVMe.kext) for my NVMe controller.
The HighPointNVMe.kext is not loaded after reboot.
I'm sure the HighPointNVMe.kext is installed correctly.
And this driver works fine in 10.14.6.
After I reboot, kextstat command shows only apple IONVMeFamily is loaded,
HighPointNVMe.kext is not loaded.
I tried kextutil command, please check the output:
sh-3.2# kextutil -ntv 4 /Library/Extensions/HighPointNVMe.kext/
Kext library architecture set to x86_64.
Defaulting to kernel file '/System/Library/Kernels/kernel'
Kext library recording diagnostics for: validation authentication dependencies warnings.
Reading loaded kext info from kernel.
/Library/Extensions/HighPointNVMe.kext appears to be loadable (including linkage for on-disk libraries).
(Seems the driver is loadable)
I also tried following cmds to update kext cache.
kextcache -system-prelinked-kernel
kextcache -invalidate /
Kextcache --clear-stage
sudo kextcache -update-volume / -Installer
and these command didn't work.
any advice and suggestions will be greatly appreciate.
