SPL TwinTube 1.16.0 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The actual developer of this software for Mac is Sound Performance Lab.
The following version: 1.2 is the most frequently downloaded one by the program users. The common filename for the program's installer is spl_twintube_native_mac_1_.dmg. The application lies within Audio & Video Tools, more precisely Editors & Converters. We recommend checking the downloaded files with any free antivirus.
From the developer:
As with all Analog Code plug-ins, the TwinTube plug-in is modeled after an SPL analog hardware processor. In this case the TwinTube processor of SPL's RackPack modular system has been the paragon. The TwinTube combines the two main artifacts that can be produced with tubes: harmonics and saturation effects.
Our programmers did a great job in creating a very good sounding tube simulation.
You may want to check out more software for Mac, such as Super Player Lite or RoomEQWizard, which might be similar to SPL TwinTube.
