So, why do we get Soundflower Installation Failed error?
After a bit of research, I found the answer on StackExchange, according to the author alecail, this is due to System Integrity Protection. El Capitan and higher versions require kext to be signed in order to load them. This one gets its kext installed in /Library/Extensions/ and not in /System/Library/Extensions as previous versions were
However, his solution didn’t work for me. Thankfully after a bit of research, I was able to dig in the kext signed version from the developer. Follow the steps.

Fixing Soundflower Installation Failed

1. Download the signed version of Soundflower using this link. Download the file that says “Soundflower-2.0b2.dmg” and install the dmg on your Mac like you install any other app. Simply, run the Soundflower package installer by double-clicking on the pkg file. Depending on your macOS setting, you might see an error from GateKeeper.
2. To bypass it, you need to temporarily disable GateKeeper. Go to System Preferences choose Security & Privacy and then click the General, next, to make any changes you have to click the Padlock icon in the bottom left corner to unlock the settings. Next, click on Open Anyway, next to Soundflower.pkg was blocked.
3. Accept the security warning and go back and click on the Soundflower package, once done, you’ll be able to install the signed version with no problem
4. Now, open System Preferences on your Mac, select Sounds, switch to the Output tab and set Soundflower (2ch) as the device for sound output. A quick way to test if Soundflower is working or not is by start playing any audio file, while Soundflower is ch2 is select for output. You shouldn’t be able to hear anything.
5. Now, open Quicktime or any audio recording software. QuickTime allows the Mac user to play movie files, but it can also be used to record screencast and audio. Since it’s free and built-in, we’ll use it for this instance. However, if you want more control, you can use a free app like Simple Recorder. We use it and it works fine.
6. Go to File and choose Audio Recording, a new window will pop-up. Click on the drop-down arrow next to the recording icon and set the audio source select Soundflower ch2 and start audio recording. you won’t hear anything but your Mac’s internal audio will record in the background.

The only downside is, you can’t hear want’s being recorded, so make sure you place close attention to the timestamps of the audio you want to record. Once you are done, simply click on the stop icon on QuickTime icon to stop the recording. It’ll show you a preview your recorded file.
Again, remember, you won’t be able to hear anything since you have set the output source to Soundflower in the Sound setting of your Mac. So, you need to reverse the changes you did there (set the Sound output to speaker or headphones) and listen to your recording. If you are satisfied with your recording, save it on your desktop or something. And that’s it.

How To Use Soundflower

Free Inter-application Audio Routing Utility for macOS

Soundflower presents itself as one of two audio devices (2ch / 16ch). The 2-channel device is sufficient for most situations.
To send the output of one application to another, select Soundflower as the output device in the first application and Soundflower as the input device within the second application.
Download
If an application does not allow you to specify audio devices, you can make Soundflower the default input or output device inside the Sound panel in the System Preferences, or with the Audio MIDI Setup utility application.
The 16-channel device is provided for more complex routing situations, and can be used with more than two applications simultaneously if the applications support audio routing to any channel, as Max/MSP does.
Note that Soundflower’s audio channels represent a global audio space. If more than one application is sending its output to the same channel, the audio will be mixed. If you want an application to send and receive audio through Soundflower, (for instance using Max/MSP to manipulate and return another application’s audio) you must send and receive the audio on different audio channels or a feedback loop will be created.
If you are hearing clicks or breakups, try increasing the buffer size of both applications (set within each application).
