macOS Releases Notes
Included here as easy reference and reminder to currently more common releases of macOS, as reminder of which codename is which release.
When get into low-level things like virtual drivers, increasingly strict security measures by Apple in each release of macOS or security patches can easily break – or make installation/use significantly more tricky. To keep in mind when considering any upgrading.
| macOS | Codename | CPU support | App supp. | Comments |
| 10.13 | High Sierra | 64-bit Intel | 32/64-bit Intel | IM2713, 1o?, 11? |
| 10.14 | Mojave | 64-bit Intel | 32/64-bit Intel | Last macOS that can run Office 2011, Adobe non-subscr. SW, .. |
| 10.15 | Catalina | 64-bit Intel | 64-bit Intel | IM2720 Looks like (google searches) Soundflower is NOT compatible, look at using BlackHole. |
| 11.0 | Big Sur | 64-bit Intel and ARM | 64-bit Intel and ARM | none yet |

Link to Soundflower software in that article – cycling74.com/soundflower-landing-page – is broken.
From rogueamoeba.com/freebies/soundflower/:
Soundflower is an open source kernel extension for MacOS, designed to create a virtual audio output device that can also act as an input.
Initial development and maintenance of Soundflower was done by Cycling ’74. In 2014, Cycling ’74 passed stewardship of Soundflower to Rogue Amoeba, but we ultimately didn’t have the time or resources to improve the product.
Thankfully, at the end of 2015, Soundflower’s original author Matt Ingalls picked up the baton. The project can now be found via this GitHub link. If you’re looking to use Soundflower, that’s the link to visit.
If you’ve previously used Soundflower, or are simply looking for a reliable tool to route audio between applications on your Mac, you may be interested in Loopback. (More below on this page)

Someone finally came up with a Soundflower replacement, and it’s free for Mac users
By James Russell 28 October 2019
Those using newer versions of macOS can now get custom audio routing with Blackhole
Ex Soundflower users may have a new solution for audio routing on Mac, thanks to a free solution posted recently to GitHub by Existential Audio.
