I want to delete HighPointNVMe.kext. (driver for my NVMe Controller)

so I delete /Library/Extensions/HighPointNVMe.kext.

clear the cache.

kextcache -i /

and reboot.

but the kext is still loaded.

sh-3.2# kextstat |grep NVMe

sh-3.2#

the HighPointNVMe.kext is deleted from /Library/Extension and /Library/StagedExtensions/Library/Extensions/

in the "about this Mac" --> "System Report" --> "Extensions" dialog. the HighPointNVMe is not listed.

the kext is loaded, but you can't find where it is.

did I miss something?

I am having this problem with Soundflower and an old Blackmagic Framebuffer kext in Big Sur:

Code Block $ sudo kextstat | grep -i soundfl
  168    0 0xffffff7fa0271000 0x3000     0x3000     com.Cycling74.driver.Soundflower (2) 2D779840-7439-31E5-8A66-D786C3F47B75 <94 6 5 3>
$ sudo kextstat | grep -i blackmag
  167    0 0xffffff7f9ff1f000 0x2000     0x2000     com.blackmagic-design.desktopvideo.iokit.framebufferdriver (10.5.2) C260C085-A85B-363A-A9B6-74336D16BC49 <115 6 5 3>

I think they are in a cache, but kmutil won't update the boot cache:

Code Block $ sudo kmutil install --update-all --force --volume-root /Volumes/Macintosh\ HD
