The installation failed. I' am facing an issue while installing SoundFlower.

[hardeep-singh]

Mac version is 10.13.4. The error message is:- The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.

Same problem. Console shows: default 22:22:37.780358 +0200 kextd Kext rejected due to system policy: <OSKext 0x7fd3e43168e0 [0x7fff9a194af0]> { URL = "file:///Library/StagedExtensions/Library/Extensions/Soundflower.kext/", ID = "com.Cycling74.driver.Soundflower" } default 22:22:37.780457 +0200 kextd com.Cycling74.driver.Soundflower failed security checks; failing.

Probably a bug in the installer: https://developer.apple.com/library/content/technotes/tn2459/_index.html#//apple_ref/doc/uid/DTS40017658-CH1-TNTAG3

If you're using High Sierra, I read somewhere in a description somewhere that it will fail the first time, and then you need to go to your system preferences and allow an extension to be installed manually from the security and privacy pane, and then it should work.

"IF INSTALLING ON HIGH SIERRA The first attempt to install will display a security alert, then fail. Afterwards, you need to go into System Preferences "Security & Privacy - General" pane and give permission to allow the install signed by the developer "MATT INGALLS". After giving permission, you will be able to run the installer successfully." https://github.com/mattingalls/Soundflower/releases/tag/2.0b2

I have a similar problem, though. For me, I have to manually allow my mac to open the package that opens the installer, and then the installer failed, but it didn't show another thing for me to allow permissions to open or install on my mac. I restarted my computer, and it still didn't help!

[wAuner]

Still having the problem. Any update on this?

[mattingalls]

@wAuner email me matt@sonomatics.com with exact details of what you are doing and i can try to help

[eclab]

The problem occurs on High Sierra regardless of whether you've given security permission.

Step 1. Run the installer. Step 2. Go to System Preferences Security & Privacy and give permission. Step 3. Continue to run the installer (or quit it and run it again). Step 4. "The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance." Step 5. Grumble a lot and run the uninstallation script.

[ahaverdings]

For me the problem was that I could now "Allow" the application. https://apple.stackexchange.com/questions/323668/allow-button-not-working-in-system-preferences this thread showed me (not the accepted answer) in the log that Garageband was not shut down and making external connection with my ipad preventing the "Allow". Once I broke the connection I could press allow and the installation was successful.

"For anyone struggling with a failed installation of soundflower 2, what you need to do is attempt the install, and when it says that it has failed, DO NOT CLOSE THE WINDOW. At that point make sure you quit system preferences, re-open system preferences, and under Security & Privacy, click allow where it says Matt Ingals has been blocked from opening. After that, close the window with the failed installation, and attempt the installation again. It should work properly."

I found the solution in the comments section from Maximus De on Youtube to this video: https://www.youtube.com/watch?v=kxx0gNyfXV8 The method in the video itself did not work for me, but the comment from Maximus did.

[eclab]

That video has the feel of voodoo rather than solution.

However, I have been able to get Soundflower installed by bypassing the graphical installer entirely and using the "install" terminal command. Hopefully this repeatable positive example should be enough to help the developers nail down the problem with their installer package. It looks like something (perhaps a timeout?) is causing the graphical installer to fail prematurely.

1. Unpack the Soundflower-2.0b2.dmg disk image.
2. In the terminal, type: cd /Volumes/Soundflower-2.0b2
3. Then: sudo installer -pkg Soundflower.pkg -target / [type in your password if prompted]
4. When you’re told that this has failed, go to “Security and Privacy” in System Preferences, and permit the software to load. You may need to click ”Allow...”, then select “MATT INGALLS”. Then do steps 2 and 3 again.
5. Wait a long time. It takes quite a while to install for no good reason. [I suspect the problem with the package is here]
6. At this point, SoundFlower2ch and 64ch will appear as audio devices.

@eclab Spent the last 3 Hours messing with Xcode project settings to no avail but this works beautifully!

[Shaolo]

eclabs instructions worked for me.

[rahatlukumich]

I had the same problem as ahaverdings, but in my case it was iMovie that was preventing the "Allow".

Thanks so much, It worked perfectly.

[julianknowles01]

On High Sierra - make sure you quit all applications before running the installer. I was having the same errors and then I quit everything and followed the Terminal installation instructions above and it finally worked. YMMV

[eyexx]

@eclab it worked for me! thanks

The problem occurs on Mojave with no option to give security permission.

Step 1. Run the installer Step 2. it fails "The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance." Step 3. Tried installing from terminal sudo installer -pkg Soundflower.pkg -target / and brew cask install soundflower, same error Step 4. Go to System Preferences Security & Privacy and do not see option to give permission. Step 5. Continue to run the installer (or quit it and run it again), and restart System Preferences Security, same error, no prompt for permission

Hello, ther's a new app named BlackHole instead of SoundFlower. I've installed and it's works great!

[gdudek]

The solution from moduloapparent worked well for me (as for others). It's not "voodoo". It's because the signing authority required isn't remembered for non-apps after the program exits (which is super annoying). You could also turnoff integrity protection, I guess.

I am still having a failure after granting permission.

[Jahnzilla]

Unfortunately I'm unable to get this installed on Macbook Pro 2021 with Big Sur. I get to the stage where I open Security & Privacy upon the failed installation but no option to say a blocked application from Matt Ingals shows. Has anyone else had success with Big Sur?

[mechanicalpencilwitheraser]

I have the same issue with Jahnzilla, I even restarted and went to startup security utility and cicked it to be from full security to reduced security and when i restarted it was the same situation. there is no option to allow anything else in security and privacy. and all this, because i am trying to cast sound from my desktop (VLC) to my chromecast. I would greatly appreciate a solution
