This is a different issue comparing to https://github.com/RogueAmoeba/Soundflower-Original/issues/96

I migrated my macOS 10.15.4 Catalina from Mac Pro 2013 to a new Mac mini 2018. All kexts are auto-disabled. Soundflower kext driver doesn't come to the System Security Preferences to allow me to allow it. I tried re-running the installer, installation fails; tried uninstall it completely and then install it again, the installer still fails during the installation step, saying that I need to ask the software vendor for assistance.

P.S.: I am fully aware that Soundflower is a driver-only installation.

I encountered the same problem today -- at the end of installation after "Validating packages" it says "The installation failed". I also tried running the installer on the command line to see if I could get a more detailer error, and it gave me:

% sudo installer -pkg Soundflower.pkg -target /
Password:
installer: Package name is Soundflower
installer: Installing at base path /
installer: The install failed. (The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance. An error occurred while running scripts from the package “Soundflower.pkg”.)

hitting with the same error

Update: I hacked mattin's latest pkg package and found the latest content of the post-installation script as follows:

Let me test whether "not touching /Library/Extensions" will work with this case.

Ladies and Gentlemen, this is the error output during post-installation when executing kextload:

Last login: Sun Jun 14 09:52:40 on ttys000
> /Library/Extensions ||||| sudo kextload /Library/Extensions/Soundflower.kext

/Library/Extensions/Soundflower.kext failed to load - (libkern/kext) system policy prevents loading; check the system/kernel logs for errors or try kextutil(8).

system.log:

ShikiSuen commented 4 years ago

At this point, the issue is related to how the kext will be written to handle the Service exited with abnormal code: 1 error. This is far from my ability range.

Calling @mattingalls for help.

Temporary workaround (steps): (Notice to Japanese users: 解決方法でなく、一時的の応対方法です。)

1) Logging into macOS Recovery mode (and log in your macOS admin account if prompted). 2) Open terminal and run spctl kext-consent add 3G47DU9NXM and reboot your machine. 3) Reboot back to the macOS and run the Installer again. -- If prompts for kernel extension permission, approve it. -- If not (or failed), go to System Preferences and manually approve all kexts from @mattingalls, and then run installer again if necessary. // Previously, his kexts are not shown in the approvable list. However, the terminal command executed in the Recovery OS made his kexts approvable now.

This should be good for all T2-equipped mac computer models.

Note that the 3G47DU9NXM indicates the development team certificate used in the kext file.

Before going through Recovery Mode, after failed install it's worth trying System Preferences -> Security & Privacy -> tab General, and "Allow software from developer XXXXX" More: http://kb.mit.edu/confluence/display/istcontrib/Approving+Kernel+Extensions+for+macOS
