Driver failed to load , 10.15 Beta (19A558d)

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.
