[Solved] How to remove the SoftRAID kext from the extension folder?

After uninstalling SoftRAID 6.1 from the menu option in the SoftRAID app, and rebooting.  I notice that the kext and the application folder is still around.  I was able to delete the SoftRaid folder from the /Applications folder

% ls -l /Library/StagedExtensions/Library/Extensions/
total 0
drwxr-xr-x@ 3 root  wheel  96 Oct 20 20:48 SoftRAID.kext

The extension doesn't appear to be loaded

% kextstat -l  | grep -i "softraid"
Executing: /usr/bin/kmutil showloaded --list-only
No variant specified, falling back to release

Removing it doesn't seem to be allowed:

% sudo kextunload /Library/StagedExtensions/Library/Extensions/SoftRAID.kext
Executing: /usr/bin/kmutil unload -p /Library/StagedExtensions/Library/Extensions/SoftRAID.kext
Error Domain=KMErrorDomain Code=3 "Error occurred unloading extensions: Missing extension with identifier com.softraid.driver.SoftRAID : Could not find: Extension with identifier 'com.softraid.driver.SoftRAID' not found" UserInfo={NSLocalizedDescription=Error occurred unloading extensions: Missing extension with identifier com.softraid.driver.SoftRAID : Could not find: Extension with identifier 'com.softraid.driver.SoftRAID' not found}
% sudo rm -rf /Library/StagedExtensions/Library/Extensions/SoftRAID.kext
rm: /Library/StagedExtensions/Library/Extensions/SoftRAID.kext/Contents/_CodeSignature/CodeResources: Operation not permitted
rm: /Library/StagedExtensions/Library/Extensions/SoftRAID.kext/Contents/_CodeSignature: Operation not permitted
rm: /Library/StagedExtensions/Library/Extensions/SoftRAID.kext/Contents/MacOS/softraidd: Operation not permitted
...
...

 

Manual removal seems quite involved: https://grafxflow.co.uk/blog/mac-os-x/delete-ioplatformpluginfamilykext-macos-big-sur

Via this: https://stackoverflow.com/questions/46535279/what-is-library-stagedextensions-for-and-how-to-remove-extensions

This did the trick:

sudo kextcache -prune-staging

I use:

sudo kmutil clear-staging
sudo kextcache -i /

and restart

 

But if you install all components in the utility menu, it should accomplish this. You should not have to go through manual removal of components, however (unless there is a problem doing it with SoftRAID)

I assume you are doing this to investigate your kernel panic bugs?
